4 Five Characteristics of Teamwork

5 Training

Definition of TeamA team is a small number of people with complementary

skills who are committed to a common purpose performance goals and approach for which

they are mutually accountable )Katzenbach and Smith 1993(A team differs from a group in that it is united by a common

function and set of goals

Best Teams

1 A team functions best if there is a shared vision a shared problem statement a goal that all team members can support in other words a pre-determined

objective that everyone agrees upon2 A champion will greatly improve the chance of team success A champion is an individual so committed to the project that they will make sure that nothing

falls through the crackshellip3 A successful team must have

bullcompetence -- skills appropriate to the project or ready access to those skillsbulltrust -- trust develops from team members getting to know what they can expect

of one anotherbullvelocity -- jargon for the ability to make decisions and take action quickly

4 All projects have three kinds of risk which must be assessed and dealt withtechnical -- is the project technically doableorganizational -- do the relevant managers support the projectpersonal -- is your heart in it

Team RolesThere are nine team roles defined to help the team function more effectively

Organizer ndash a person who visualizes and plans for the whole design process

Motivator ndash a person who takes care of the schedule and goals of the teamPusher ndash an active person who makes team work fasterSolver ndash an imaginative person who deals mainly with problem resolutionGatherer ndash a person who is good at collecting information and

communicating with other teamsListener ndash a perceptive person who can listen and combine the ideas and

statements of othersCompleter ndash a careful person who specializes in eliminating design defectsSpecialist ndash a dedicated person who is extremely skilled and has a lot of

knowledge in a specific areaEvaluator ndash a person who has good strategic skills keeps the balance

between immediate needs and long-term goals and weighs consequences

Five Characteristics of TeamworkThere are five characteristics that are the keys to a winning team The following characteristics are arranged in order of importance from highest to lowest1 Shared ValuesTeam members establish shared values and common goals and make the commitment to succeed2 Mutual TrustTeam members trust each other to get the job done They understand their role on the team is important and to put forth maximum effort to fulfill their promisesEveryone should express their opinions feelings and doubts Share information with your team This will help everyone to understand the project in greater detailTeam members should be enthusiastic with each other This will help produce the best performance as a team3 Inspiring VisionProvides direction and motivates the teamTeam members understand what needs to be done and how it can be doneThe focus should be on exceeding customer satisfaction The team should be inspired to work hard so that the products performance quality and cost are all rated excellent4 Skill TalentA team is stronger when team members are skilled in their discipline In addition when people are from different backgrounds they can work as a team to solve complex problemsA skilled individual is important however it is not as important as an individual who is a better team member A good team member prioritizes the values of the team trust on the team and the vision of the team5 Rewards Team members should be rewarded for their hard work and determination Rewards include going

out to eat a bonus or a promotionAs a manager it is your job to give positive reinforcement to your team members People feel good when

people show their appreciation for their contributions

Human Factors

As is well known Engineering Design is concerned with the satisfaction of human needs With this in mind it is quite obvious that there are many areas in which human factors must be taken into account in the design analysis The basic consideration in determining whether or not human factors are important is the possibility of a direct man-machine relationship Having determined the possibility and extent of involvement it is then necessary to consider the form of this relationship be it Anthropometric Ergonomic

Physiological Psychological

Human Factors35

Engineering Design is concerned with the satisfaction of human needs

In many applications human

factors must be taken into account in the design process

Man-machine interface )MMI( is very important to be considered in the design process

Human Factors in Engineering Design

Human factors in man-machine relationship have the following formsbull Anthropometric

)Human interaction in static sense dimensions of body)

bull Ergonomic)Human interaction in dynamic sense repeated tasks)

bull Physiological)Human interaction with body characteristics)

bull Psychological)Human interaction with mental activities)

37Human Factors

Man-Machine Interface

38Human Factors

Man-Machine Interface

The Design Engineer can determine the relative importance of human factors in his design

Anthropometric human factors are related to the physical size of humans it is man-machine interaction in static sense

One of the most common problems is that of driver accommodation in automobiles

Some may have experienced difficulties in either getting in or out reaching the controls or adequate visibility

These may have been due to inadequate attention to the nature of the physical dimensions of humans

40Human Factors

Anthropometric Factors

Human Factors41

Ergonomic Factors

Importance when the human operator is involved with the machine in a dynamic sense

A human is required to exert a force or perhaps supply work to the machine

It should be obvious that the effective operation of a machine over long periods of time will depend upon the matching of requirements to human capability

42Human Factors

Ergonomic Factors

Human Factors43

Ergonomic Factors

One simple example is that when the brake operating force is higher than can be normally tolerated The driver will cope with the situation at first but if the brake operation is frequent muscle fatigue will eventually occur and a dangerous situation will develop

The capability for performing mechanical tasks of this type depends upon

The physical ability of the operator The range of movement required The speed of movement The duration of the activity The position of the operator The environmental condition

44Human Factors

Ergonomic Factors

Human Factors45

Physiological Factors

Physiological factors are of concern when the physicochemical characteristics of the body are significant

As far as body functions are concerned these involve the neurological muscular respiratory vascular and sensory systems

The exterior manifestations can be grouped according to the response to various inputs such as

Visual Auditory Tactile kinesthetic and taste senses Environment

Color discrimination is impaired when illumination levels are low and this can lead to unexpected difficulties in comprehension

An associated problem of illumination which has a critical effect on contrast is that of glare and shadow formation These can be controlled by careful design of lighting systems and selection of materials and colors

46Human Factors

Physiological Factors

An excessive level of noise pollution is in fact undesirable for a number of reasons

Leads to degradation of speech intelligibility Will lead to physical damage to the human auditory system Hinders mental activity due to distracting influences Can lead to psychological and mental disorders if sustained

47Human Factors

Physiological Factors

The speech interference level )SIL( is a measure of the destructiveness of noise It is determined by the level of noise in certain frequency bands

High levels of sound intensity cause pain and even physical damage

The usually accepted threshold of pain is at about 05 Wm2

48Human Factors

Physiological Factors

Human Factors49

Psychological Factors

Psychological considerations in human factors analysis are concerned with the mental activity relationship between man and the machine This involves

bull Interpretation of informationbull Motivation and fatiguebull Decision makingbull Aesthetics

Human Factors50

Psychological Factors

These factors are concerned with the manner of presentation to minimize the error of interpretation

The design of visual displays such as control panels instrument panels and other informative displays is a typical example of psychological factors at work

There are a number of principles which have been developed Some of these include 1 Retain the usual method of operation )eg a power switch is ON when the operating lever is DOWN

2 Use digital indicators for precise numerical values with no need for interpretation That is satisfactory only when values are constant or not changing rapidly

3 For time variable readings not requiring high accuracy use moving pointers over a fixed linear or circular scale

51Human Factors

Psychological Factors

Human Factors52

Psychological Factors

4 Arrange control movement to coincide with required direction of instrument pointer movement

5 Color coding on dials are useful in helping to recognize conditions quickly eg green-normal yellow-caution red-danger

The mechanism of the control device should be designed so that )i( Movements are easy )ii( Slackness is eliminated )iii( The operator is aware of a feedback response )iv( The system response is rapid

If this cannot be achieved the controller should incorporate some restriction so that over reaction and instability does not develop

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

4 Five Characteristics of Teamwork

5 Training

Definition of TeamA team is a small number of people with complementary

skills who are committed to a common purpose performance goals and approach for which

they are mutually accountable )Katzenbach and Smith 1993(A team differs from a group in that it is united by a common

function and set of goals

Best Teams

1 A team functions best if there is a shared vision a shared problem statement a goal that all team members can support in other words a pre-determined

objective that everyone agrees upon2 A champion will greatly improve the chance of team success A champion is an individual so committed to the project that they will make sure that nothing

falls through the crackshellip3 A successful team must have

bullcompetence -- skills appropriate to the project or ready access to those skillsbulltrust -- trust develops from team members getting to know what they can expect

of one anotherbullvelocity -- jargon for the ability to make decisions and take action quickly

4 All projects have three kinds of risk which must be assessed and dealt withtechnical -- is the project technically doableorganizational -- do the relevant managers support the projectpersonal -- is your heart in it

Team RolesThere are nine team roles defined to help the team function more effectively

Organizer ndash a person who visualizes and plans for the whole design process

Motivator ndash a person who takes care of the schedule and goals of the teamPusher ndash an active person who makes team work fasterSolver ndash an imaginative person who deals mainly with problem resolutionGatherer ndash a person who is good at collecting information and

communicating with other teamsListener ndash a perceptive person who can listen and combine the ideas and

statements of othersCompleter ndash a careful person who specializes in eliminating design defectsSpecialist ndash a dedicated person who is extremely skilled and has a lot of

knowledge in a specific areaEvaluator ndash a person who has good strategic skills keeps the balance

between immediate needs and long-term goals and weighs consequences

Five Characteristics of TeamworkThere are five characteristics that are the keys to a winning team The following characteristics are arranged in order of importance from highest to lowest1 Shared ValuesTeam members establish shared values and common goals and make the commitment to succeed2 Mutual TrustTeam members trust each other to get the job done They understand their role on the team is important and to put forth maximum effort to fulfill their promisesEveryone should express their opinions feelings and doubts Share information with your team This will help everyone to understand the project in greater detailTeam members should be enthusiastic with each other This will help produce the best performance as a team3 Inspiring VisionProvides direction and motivates the teamTeam members understand what needs to be done and how it can be doneThe focus should be on exceeding customer satisfaction The team should be inspired to work hard so that the products performance quality and cost are all rated excellent4 Skill TalentA team is stronger when team members are skilled in their discipline In addition when people are from different backgrounds they can work as a team to solve complex problemsA skilled individual is important however it is not as important as an individual who is a better team member A good team member prioritizes the values of the team trust on the team and the vision of the team5 Rewards Team members should be rewarded for their hard work and determination Rewards include going

out to eat a bonus or a promotionAs a manager it is your job to give positive reinforcement to your team members People feel good when

people show their appreciation for their contributions

Human Factors

As is well known Engineering Design is concerned with the satisfaction of human needs With this in mind it is quite obvious that there are many areas in which human factors must be taken into account in the design analysis The basic consideration in determining whether or not human factors are important is the possibility of a direct man-machine relationship Having determined the possibility and extent of involvement it is then necessary to consider the form of this relationship be it Anthropometric Ergonomic

Physiological Psychological

Engineering Design is concerned with the satisfaction of human needs

In many applications human

factors must be taken into account in the design process

Man-machine interface )MMI( is very important to be considered in the design process

Human Factors in Engineering Design

Human factors in man-machine relationship have the following formsbull Anthropometric

)Human interaction in static sense dimensions of body)

bull Ergonomic)Human interaction in dynamic sense repeated tasks)

bull Physiological)Human interaction with body characteristics)

bull Psychological)Human interaction with mental activities)

37Human Factors

Man-Machine Interface

38Human Factors

Man-Machine Interface

The Design Engineer can determine the relative importance of human factors in his design

Anthropometric human factors are related to the physical size of humans it is man-machine interaction in static sense

One of the most common problems is that of driver accommodation in automobiles

Some may have experienced difficulties in either getting in or out reaching the controls or adequate visibility

These may have been due to inadequate attention to the nature of the physical dimensions of humans

40Human Factors

Anthropometric Factors

Human Factors41

Ergonomic Factors

Importance when the human operator is involved with the machine in a dynamic sense

A human is required to exert a force or perhaps supply work to the machine

It should be obvious that the effective operation of a machine over long periods of time will depend upon the matching of requirements to human capability

42Human Factors

Ergonomic Factors

Human Factors43

Ergonomic Factors

One simple example is that when the brake operating force is higher than can be normally tolerated The driver will cope with the situation at first but if the brake operation is frequent muscle fatigue will eventually occur and a dangerous situation will develop

The capability for performing mechanical tasks of this type depends upon

The physical ability of the operator The range of movement required The speed of movement The duration of the activity The position of the operator The environmental condition

44Human Factors

Ergonomic Factors

Human Factors45

Physiological Factors

Physiological factors are of concern when the physicochemical characteristics of the body are significant

As far as body functions are concerned these involve the neurological muscular respiratory vascular and sensory systems

The exterior manifestations can be grouped according to the response to various inputs such as

Visual Auditory Tactile kinesthetic and taste senses Environment

Color discrimination is impaired when illumination levels are low and this can lead to unexpected difficulties in comprehension

An associated problem of illumination which has a critical effect on contrast is that of glare and shadow formation These can be controlled by careful design of lighting systems and selection of materials and colors

46Human Factors

Physiological Factors

An excessive level of noise pollution is in fact undesirable for a number of reasons

Leads to degradation of speech intelligibility Will lead to physical damage to the human auditory system Hinders mental activity due to distracting influences Can lead to psychological and mental disorders if sustained

47Human Factors

Physiological Factors

The speech interference level )SIL( is a measure of the destructiveness of noise It is determined by the level of noise in certain frequency bands

High levels of sound intensity cause pain and even physical damage

The usually accepted threshold of pain is at about 05 Wm2

48Human Factors

Physiological Factors

Human Factors49

Psychological Factors

Psychological considerations in human factors analysis are concerned with the mental activity relationship between man and the machine This involves

bull Interpretation of informationbull Motivation and fatiguebull Decision makingbull Aesthetics

Human Factors50

Psychological Factors

These factors are concerned with the manner of presentation to minimize the error of interpretation

The design of visual displays such as control panels instrument panels and other informative displays is a typical example of psychological factors at work

There are a number of principles which have been developed Some of these include 1 Retain the usual method of operation )eg a power switch is ON when the operating lever is DOWN

2 Use digital indicators for precise numerical values with no need for interpretation That is satisfactory only when values are constant or not changing rapidly

3 For time variable readings not requiring high accuracy use moving pointers over a fixed linear or circular scale

51Human Factors

Psychological Factors

Human Factors52

Psychological Factors

4 Arrange control movement to coincide with required direction of instrument pointer movement

5 Color coding on dials are useful in helping to recognize conditions quickly eg green-normal yellow-caution red-danger

The mechanism of the control device should be designed so that )i( Movements are easy )ii( Slackness is eliminated )iii( The operator is aware of a feedback response )iv( The system response is rapid

If this cannot be achieved the controller should incorporate some restriction so that over reaction and instability does not develop

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

5 Training

Definition of TeamA team is a small number of people with complementary

skills who are committed to a common purpose performance goals and approach for which

they are mutually accountable )Katzenbach and Smith 1993(A team differs from a group in that it is united by a common

function and set of goals

Best Teams

1 A team functions best if there is a shared vision a shared problem statement a goal that all team members can support in other words a pre-determined

objective that everyone agrees upon2 A champion will greatly improve the chance of team success A champion is an individual so committed to the project that they will make sure that nothing

falls through the crackshellip3 A successful team must have

bullcompetence -- skills appropriate to the project or ready access to those skillsbulltrust -- trust develops from team members getting to know what they can expect

of one anotherbullvelocity -- jargon for the ability to make decisions and take action quickly

4 All projects have three kinds of risk which must be assessed and dealt withtechnical -- is the project technically doableorganizational -- do the relevant managers support the projectpersonal -- is your heart in it

Team RolesThere are nine team roles defined to help the team function more effectively

Organizer ndash a person who visualizes and plans for the whole design process

Motivator ndash a person who takes care of the schedule and goals of the teamPusher ndash an active person who makes team work fasterSolver ndash an imaginative person who deals mainly with problem resolutionGatherer ndash a person who is good at collecting information and

communicating with other teamsListener ndash a perceptive person who can listen and combine the ideas and

statements of othersCompleter ndash a careful person who specializes in eliminating design defectsSpecialist ndash a dedicated person who is extremely skilled and has a lot of

knowledge in a specific areaEvaluator ndash a person who has good strategic skills keeps the balance

between immediate needs and long-term goals and weighs consequences

Five Characteristics of TeamworkThere are five characteristics that are the keys to a winning team The following characteristics are arranged in order of importance from highest to lowest1 Shared ValuesTeam members establish shared values and common goals and make the commitment to succeed2 Mutual TrustTeam members trust each other to get the job done They understand their role on the team is important and to put forth maximum effort to fulfill their promisesEveryone should express their opinions feelings and doubts Share information with your team This will help everyone to understand the project in greater detailTeam members should be enthusiastic with each other This will help produce the best performance as a team3 Inspiring VisionProvides direction and motivates the teamTeam members understand what needs to be done and how it can be doneThe focus should be on exceeding customer satisfaction The team should be inspired to work hard so that the products performance quality and cost are all rated excellent4 Skill TalentA team is stronger when team members are skilled in their discipline In addition when people are from different backgrounds they can work as a team to solve complex problemsA skilled individual is important however it is not as important as an individual who is a better team member A good team member prioritizes the values of the team trust on the team and the vision of the team5 Rewards Team members should be rewarded for their hard work and determination Rewards include going

out to eat a bonus or a promotionAs a manager it is your job to give positive reinforcement to your team members People feel good when

people show their appreciation for their contributions

Human Factors

As is well known Engineering Design is concerned with the satisfaction of human needs With this in mind it is quite obvious that there are many areas in which human factors must be taken into account in the design analysis The basic consideration in determining whether or not human factors are important is the possibility of a direct man-machine relationship Having determined the possibility and extent of involvement it is then necessary to consider the form of this relationship be it Anthropometric Ergonomic

Physiological Psychological

Engineering Design is concerned with the satisfaction of human needs

In many applications human

factors must be taken into account in the design process

Man-machine interface )MMI( is very important to be considered in the design process

Human Factors in Engineering Design

Human factors in man-machine relationship have the following formsbull Anthropometric

)Human interaction in static sense dimensions of body)

bull Ergonomic)Human interaction in dynamic sense repeated tasks)

bull Physiological)Human interaction with body characteristics)

bull Psychological)Human interaction with mental activities)

37Human Factors

Man-Machine Interface

38Human Factors

Man-Machine Interface

The Design Engineer can determine the relative importance of human factors in his design

Anthropometric human factors are related to the physical size of humans it is man-machine interaction in static sense

One of the most common problems is that of driver accommodation in automobiles

Some may have experienced difficulties in either getting in or out reaching the controls or adequate visibility

These may have been due to inadequate attention to the nature of the physical dimensions of humans

40Human Factors

Anthropometric Factors

Human Factors41

Ergonomic Factors

Importance when the human operator is involved with the machine in a dynamic sense

A human is required to exert a force or perhaps supply work to the machine

It should be obvious that the effective operation of a machine over long periods of time will depend upon the matching of requirements to human capability

42Human Factors

Ergonomic Factors

Human Factors43

Ergonomic Factors

One simple example is that when the brake operating force is higher than can be normally tolerated The driver will cope with the situation at first but if the brake operation is frequent muscle fatigue will eventually occur and a dangerous situation will develop

The capability for performing mechanical tasks of this type depends upon

The physical ability of the operator The range of movement required The speed of movement The duration of the activity The position of the operator The environmental condition

44Human Factors

Ergonomic Factors

Human Factors45

Physiological Factors

Physiological factors are of concern when the physicochemical characteristics of the body are significant

As far as body functions are concerned these involve the neurological muscular respiratory vascular and sensory systems

The exterior manifestations can be grouped according to the response to various inputs such as

Visual Auditory Tactile kinesthetic and taste senses Environment

Color discrimination is impaired when illumination levels are low and this can lead to unexpected difficulties in comprehension

An associated problem of illumination which has a critical effect on contrast is that of glare and shadow formation These can be controlled by careful design of lighting systems and selection of materials and colors

46Human Factors

Physiological Factors

An excessive level of noise pollution is in fact undesirable for a number of reasons

Leads to degradation of speech intelligibility Will lead to physical damage to the human auditory system Hinders mental activity due to distracting influences Can lead to psychological and mental disorders if sustained

47Human Factors

Physiological Factors

The speech interference level )SIL( is a measure of the destructiveness of noise It is determined by the level of noise in certain frequency bands

High levels of sound intensity cause pain and even physical damage

The usually accepted threshold of pain is at about 05 Wm2

48Human Factors

Physiological Factors

Human Factors49

Psychological Factors

Psychological considerations in human factors analysis are concerned with the mental activity relationship between man and the machine This involves

bull Interpretation of informationbull Motivation and fatiguebull Decision makingbull Aesthetics

Human Factors50

Psychological Factors

These factors are concerned with the manner of presentation to minimize the error of interpretation

The design of visual displays such as control panels instrument panels and other informative displays is a typical example of psychological factors at work

There are a number of principles which have been developed Some of these include 1 Retain the usual method of operation )eg a power switch is ON when the operating lever is DOWN

2 Use digital indicators for precise numerical values with no need for interpretation That is satisfactory only when values are constant or not changing rapidly

3 For time variable readings not requiring high accuracy use moving pointers over a fixed linear or circular scale

51Human Factors

Psychological Factors

Human Factors52

Psychological Factors

4 Arrange control movement to coincide with required direction of instrument pointer movement

5 Color coding on dials are useful in helping to recognize conditions quickly eg green-normal yellow-caution red-danger

The mechanism of the control device should be designed so that )i( Movements are easy )ii( Slackness is eliminated )iii( The operator is aware of a feedback response )iv( The system response is rapid

If this cannot be achieved the controller should incorporate some restriction so that over reaction and instability does not develop

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

4 Five Characteristics of Teamwork

5 Training

Definition of TeamA team is a small number of people with complementary

skills who are committed to a common purpose performance goals and approach for which

they are mutually accountable )Katzenbach and Smith 1993(A team differs from a group in that it is united by a common

function and set of goals

Best Teams

1 A team functions best if there is a shared vision a shared problem statement a goal that all team members can support in other words a pre-determined

objective that everyone agrees upon2 A champion will greatly improve the chance of team success A champion is an individual so committed to the project that they will make sure that nothing

falls through the crackshellip3 A successful team must have

bullcompetence -- skills appropriate to the project or ready access to those skillsbulltrust -- trust develops from team members getting to know what they can expect

of one anotherbullvelocity -- jargon for the ability to make decisions and take action quickly

4 All projects have three kinds of risk which must be assessed and dealt withtechnical -- is the project technically doableorganizational -- do the relevant managers support the projectpersonal -- is your heart in it

Team RolesThere are nine team roles defined to help the team function more effectively

Organizer ndash a person who visualizes and plans for the whole design process

Motivator ndash a person who takes care of the schedule and goals of the teamPusher ndash an active person who makes team work fasterSolver ndash an imaginative person who deals mainly with problem resolutionGatherer ndash a person who is good at collecting information and

communicating with other teamsListener ndash a perceptive person who can listen and combine the ideas and

statements of othersCompleter ndash a careful person who specializes in eliminating design defectsSpecialist ndash a dedicated person who is extremely skilled and has a lot of

knowledge in a specific areaEvaluator ndash a person who has good strategic skills keeps the balance

between immediate needs and long-term goals and weighs consequences

Five Characteristics of TeamworkThere are five characteristics that are the keys to a winning team The following characteristics are arranged in order of importance from highest to lowest1 Shared ValuesTeam members establish shared values and common goals and make the commitment to succeed2 Mutual TrustTeam members trust each other to get the job done They understand their role on the team is important and to put forth maximum effort to fulfill their promisesEveryone should express their opinions feelings and doubts Share information with your team This will help everyone to understand the project in greater detailTeam members should be enthusiastic with each other This will help produce the best performance as a team3 Inspiring VisionProvides direction and motivates the teamTeam members understand what needs to be done and how it can be doneThe focus should be on exceeding customer satisfaction The team should be inspired to work hard so that the products performance quality and cost are all rated excellent4 Skill TalentA team is stronger when team members are skilled in their discipline In addition when people are from different backgrounds they can work as a team to solve complex problemsA skilled individual is important however it is not as important as an individual who is a better team member A good team member prioritizes the values of the team trust on the team and the vision of the team5 Rewards Team members should be rewarded for their hard work and determination Rewards include going

out to eat a bonus or a promotionAs a manager it is your job to give positive reinforcement to your team members People feel good when

people show their appreciation for their contributions

Human Factors

As is well known Engineering Design is concerned with the satisfaction of human needs With this in mind it is quite obvious that there are many areas in which human factors must be taken into account in the design analysis The basic consideration in determining whether or not human factors are important is the possibility of a direct man-machine relationship Having determined the possibility and extent of involvement it is then necessary to consider the form of this relationship be it Anthropometric Ergonomic

Engineering Design is concerned with the satisfaction of human needs

In many applications human

factors must be taken into account in the design process

Man-machine interface )MMI( is very important to be considered in the design process

Human Factors in Engineering Design

Human factors in man-machine relationship have the following formsbull Anthropometric

)Human interaction in static sense dimensions of body)

bull Ergonomic)Human interaction in dynamic sense repeated tasks)

bull Physiological)Human interaction with body characteristics)

bull Psychological)Human interaction with mental activities)

37Human Factors

Man-Machine Interface

38Human Factors

Man-Machine Interface

The Design Engineer can determine the relative importance of human factors in his design

Anthropometric human factors are related to the physical size of humans it is man-machine interaction in static sense

One of the most common problems is that of driver accommodation in automobiles

Some may have experienced difficulties in either getting in or out reaching the controls or adequate visibility

These may have been due to inadequate attention to the nature of the physical dimensions of humans

40Human Factors

Anthropometric Factors

Human Factors41

Ergonomic Factors

Importance when the human operator is involved with the machine in a dynamic sense

A human is required to exert a force or perhaps supply work to the machine

It should be obvious that the effective operation of a machine over long periods of time will depend upon the matching of requirements to human capability

42Human Factors

Ergonomic Factors

Human Factors43

Ergonomic Factors

One simple example is that when the brake operating force is higher than can be normally tolerated The driver will cope with the situation at first but if the brake operation is frequent muscle fatigue will eventually occur and a dangerous situation will develop

The capability for performing mechanical tasks of this type depends upon

The physical ability of the operator The range of movement required The speed of movement The duration of the activity The position of the operator The environmental condition

44Human Factors

Ergonomic Factors

Human Factors45

Physiological Factors

Physiological factors are of concern when the physicochemical characteristics of the body are significant

As far as body functions are concerned these involve the neurological muscular respiratory vascular and sensory systems

The exterior manifestations can be grouped according to the response to various inputs such as

Visual Auditory Tactile kinesthetic and taste senses Environment

Color discrimination is impaired when illumination levels are low and this can lead to unexpected difficulties in comprehension

An associated problem of illumination which has a critical effect on contrast is that of glare and shadow formation These can be controlled by careful design of lighting systems and selection of materials and colors

46Human Factors

Physiological Factors

An excessive level of noise pollution is in fact undesirable for a number of reasons

Leads to degradation of speech intelligibility Will lead to physical damage to the human auditory system Hinders mental activity due to distracting influences Can lead to psychological and mental disorders if sustained

47Human Factors

Physiological Factors

The speech interference level )SIL( is a measure of the destructiveness of noise It is determined by the level of noise in certain frequency bands

High levels of sound intensity cause pain and even physical damage

The usually accepted threshold of pain is at about 05 Wm2

48Human Factors

Physiological Factors

Human Factors49

Psychological Factors

Psychological considerations in human factors analysis are concerned with the mental activity relationship between man and the machine This involves

bull Interpretation of informationbull Motivation and fatiguebull Decision makingbull Aesthetics

Human Factors50

Psychological Factors

These factors are concerned with the manner of presentation to minimize the error of interpretation

The design of visual displays such as control panels instrument panels and other informative displays is a typical example of psychological factors at work

There are a number of principles which have been developed Some of these include 1 Retain the usual method of operation )eg a power switch is ON when the operating lever is DOWN

2 Use digital indicators for precise numerical values with no need for interpretation That is satisfactory only when values are constant or not changing rapidly

3 For time variable readings not requiring high accuracy use moving pointers over a fixed linear or circular scale

51Human Factors

Psychological Factors

Human Factors52

Psychological Factors

4 Arrange control movement to coincide with required direction of instrument pointer movement

5 Color coding on dials are useful in helping to recognize conditions quickly eg green-normal yellow-caution red-danger

The mechanism of the control device should be designed so that )i( Movements are easy )ii( Slackness is eliminated )iii( The operator is aware of a feedback response )iv( The system response is rapid

If this cannot be achieved the controller should incorporate some restriction so that over reaction and instability does not develop

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

5 Training

Definition of TeamA team is a small number of people with complementary

skills who are committed to a common purpose performance goals and approach for which

they are mutually accountable )Katzenbach and Smith 1993(A team differs from a group in that it is united by a common

function and set of goals

Best Teams

1 A team functions best if there is a shared vision a shared problem statement a goal that all team members can support in other words a pre-determined

objective that everyone agrees upon2 A champion will greatly improve the chance of team success A champion is an individual so committed to the project that they will make sure that nothing

falls through the crackshellip3 A successful team must have

bullcompetence -- skills appropriate to the project or ready access to those skillsbulltrust -- trust develops from team members getting to know what they can expect

of one anotherbullvelocity -- jargon for the ability to make decisions and take action quickly

4 All projects have three kinds of risk which must be assessed and dealt withtechnical -- is the project technically doableorganizational -- do the relevant managers support the projectpersonal -- is your heart in it

Team RolesThere are nine team roles defined to help the team function more effectively

Organizer ndash a person who visualizes and plans for the whole design process

Motivator ndash a person who takes care of the schedule and goals of the teamPusher ndash an active person who makes team work fasterSolver ndash an imaginative person who deals mainly with problem resolutionGatherer ndash a person who is good at collecting information and

communicating with other teamsListener ndash a perceptive person who can listen and combine the ideas and

statements of othersCompleter ndash a careful person who specializes in eliminating design defectsSpecialist ndash a dedicated person who is extremely skilled and has a lot of

knowledge in a specific areaEvaluator ndash a person who has good strategic skills keeps the balance

between immediate needs and long-term goals and weighs consequences

Five Characteristics of TeamworkThere are five characteristics that are the keys to a winning team The following characteristics are arranged in order of importance from highest to lowest1 Shared ValuesTeam members establish shared values and common goals and make the commitment to succeed2 Mutual TrustTeam members trust each other to get the job done They understand their role on the team is important and to put forth maximum effort to fulfill their promisesEveryone should express their opinions feelings and doubts Share information with your team This will help everyone to understand the project in greater detailTeam members should be enthusiastic with each other This will help produce the best performance as a team3 Inspiring VisionProvides direction and motivates the teamTeam members understand what needs to be done and how it can be doneThe focus should be on exceeding customer satisfaction The team should be inspired to work hard so that the products performance quality and cost are all rated excellent4 Skill TalentA team is stronger when team members are skilled in their discipline In addition when people are from different backgrounds they can work as a team to solve complex problemsA skilled individual is important however it is not as important as an individual who is a better team member A good team member prioritizes the values of the team trust on the team and the vision of the team5 Rewards Team members should be rewarded for their hard work and determination Rewards include going

out to eat a bonus or a promotionAs a manager it is your job to give positive reinforcement to your team members People feel good when

people show their appreciation for their contributions

Human Factors

As is well known Engineering Design is concerned with the satisfaction of human needs With this in mind it is quite obvious that there are many areas in which human factors must be taken into account in the design analysis The basic consideration in determining whether or not human factors are important is the possibility of a direct man-machine relationship Having determined the possibility and extent of involvement it is then necessary to consider the form of this relationship be it Anthropometric Ergonomic

Engineering Design is concerned with the satisfaction of human needs

In many applications human

factors must be taken into account in the design process

Man-machine interface )MMI( is very important to be considered in the design process

Human Factors in Engineering Design

Human factors in man-machine relationship have the following formsbull Anthropometric

)Human interaction in static sense dimensions of body)

bull Ergonomic)Human interaction in dynamic sense repeated tasks)

bull Physiological)Human interaction with body characteristics)

bull Psychological)Human interaction with mental activities)

37Human Factors

Man-Machine Interface

38Human Factors

Man-Machine Interface

The Design Engineer can determine the relative importance of human factors in his design

Anthropometric human factors are related to the physical size of humans it is man-machine interaction in static sense

One of the most common problems is that of driver accommodation in automobiles

Some may have experienced difficulties in either getting in or out reaching the controls or adequate visibility

These may have been due to inadequate attention to the nature of the physical dimensions of humans

40Human Factors

Anthropometric Factors

Human Factors41

Ergonomic Factors

Importance when the human operator is involved with the machine in a dynamic sense

A human is required to exert a force or perhaps supply work to the machine

It should be obvious that the effective operation of a machine over long periods of time will depend upon the matching of requirements to human capability

42Human Factors

Ergonomic Factors

Human Factors43

Ergonomic Factors

One simple example is that when the brake operating force is higher than can be normally tolerated The driver will cope with the situation at first but if the brake operation is frequent muscle fatigue will eventually occur and a dangerous situation will develop

The capability for performing mechanical tasks of this type depends upon

The physical ability of the operator The range of movement required The speed of movement The duration of the activity The position of the operator The environmental condition

44Human Factors

Ergonomic Factors

Human Factors45

Physiological Factors

Physiological factors are of concern when the physicochemical characteristics of the body are significant

As far as body functions are concerned these involve the neurological muscular respiratory vascular and sensory systems

The exterior manifestations can be grouped according to the response to various inputs such as

Visual Auditory Tactile kinesthetic and taste senses Environment

Color discrimination is impaired when illumination levels are low and this can lead to unexpected difficulties in comprehension

An associated problem of illumination which has a critical effect on contrast is that of glare and shadow formation These can be controlled by careful design of lighting systems and selection of materials and colors

46Human Factors

Physiological Factors

An excessive level of noise pollution is in fact undesirable for a number of reasons

Leads to degradation of speech intelligibility Will lead to physical damage to the human auditory system Hinders mental activity due to distracting influences Can lead to psychological and mental disorders if sustained

47Human Factors

Physiological Factors

The speech interference level )SIL( is a measure of the destructiveness of noise It is determined by the level of noise in certain frequency bands

High levels of sound intensity cause pain and even physical damage

The usually accepted threshold of pain is at about 05 Wm2

48Human Factors

Physiological Factors

Human Factors49

Psychological Factors

Psychological considerations in human factors analysis are concerned with the mental activity relationship between man and the machine This involves

bull Interpretation of informationbull Motivation and fatiguebull Decision makingbull Aesthetics

Human Factors50

Psychological Factors

These factors are concerned with the manner of presentation to minimize the error of interpretation

The design of visual displays such as control panels instrument panels and other informative displays is a typical example of psychological factors at work

There are a number of principles which have been developed Some of these include 1 Retain the usual method of operation )eg a power switch is ON when the operating lever is DOWN

2 Use digital indicators for precise numerical values with no need for interpretation That is satisfactory only when values are constant or not changing rapidly

3 For time variable readings not requiring high accuracy use moving pointers over a fixed linear or circular scale

51Human Factors

Psychological Factors

Human Factors52

Psychological Factors

4 Arrange control movement to coincide with required direction of instrument pointer movement

5 Color coding on dials are useful in helping to recognize conditions quickly eg green-normal yellow-caution red-danger

The mechanism of the control device should be designed so that )i( Movements are easy )ii( Slackness is eliminated )iii( The operator is aware of a feedback response )iv( The system response is rapid

If this cannot be achieved the controller should incorporate some restriction so that over reaction and instability does not develop

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

5 Training

Definition of TeamA team is a small number of people with complementary

skills who are committed to a common purpose performance goals and approach for which

they are mutually accountable )Katzenbach and Smith 1993(A team differs from a group in that it is united by a common

function and set of goals

Best Teams

1 A team functions best if there is a shared vision a shared problem statement a goal that all team members can support in other words a pre-determined

objective that everyone agrees upon2 A champion will greatly improve the chance of team success A champion is an individual so committed to the project that they will make sure that nothing

falls through the crackshellip3 A successful team must have

bullcompetence -- skills appropriate to the project or ready access to those skillsbulltrust -- trust develops from team members getting to know what they can expect

of one anotherbullvelocity -- jargon for the ability to make decisions and take action quickly

4 All projects have three kinds of risk which must be assessed and dealt withtechnical -- is the project technically doableorganizational -- do the relevant managers support the projectpersonal -- is your heart in it

Team RolesThere are nine team roles defined to help the team function more effectively

Organizer ndash a person who visualizes and plans for the whole design process

Motivator ndash a person who takes care of the schedule and goals of the teamPusher ndash an active person who makes team work fasterSolver ndash an imaginative person who deals mainly with problem resolutionGatherer ndash a person who is good at collecting information and

communicating with other teamsListener ndash a perceptive person who can listen and combine the ideas and

statements of othersCompleter ndash a careful person who specializes in eliminating design defectsSpecialist ndash a dedicated person who is extremely skilled and has a lot of

knowledge in a specific areaEvaluator ndash a person who has good strategic skills keeps the balance

between immediate needs and long-term goals and weighs consequences

Five Characteristics of TeamworkThere are five characteristics that are the keys to a winning team The following characteristics are arranged in order of importance from highest to lowest1 Shared ValuesTeam members establish shared values and common goals and make the commitment to succeed2 Mutual TrustTeam members trust each other to get the job done They understand their role on the team is important and to put forth maximum effort to fulfill their promisesEveryone should express their opinions feelings and doubts Share information with your team This will help everyone to understand the project in greater detailTeam members should be enthusiastic with each other This will help produce the best performance as a team3 Inspiring VisionProvides direction and motivates the teamTeam members understand what needs to be done and how it can be doneThe focus should be on exceeding customer satisfaction The team should be inspired to work hard so that the products performance quality and cost are all rated excellent4 Skill TalentA team is stronger when team members are skilled in their discipline In addition when people are from different backgrounds they can work as a team to solve complex problemsA skilled individual is important however it is not as important as an individual who is a better team member A good team member prioritizes the values of the team trust on the team and the vision of the team5 Rewards Team members should be rewarded for their hard work and determination Rewards include going

out to eat a bonus or a promotionAs a manager it is your job to give positive reinforcement to your team members People feel good when

people show their appreciation for their contributions

Human Factors

As is well known Engineering Design is concerned with the satisfaction of human needs With this in mind it is quite obvious that there are many areas in which human factors must be taken into account in the design analysis The basic consideration in determining whether or not human factors are important is the possibility of a direct man-machine relationship Having determined the possibility and extent of involvement it is then necessary to consider the form of this relationship be it Anthropometric Ergonomic

Engineering Design is concerned with the satisfaction of human needs

In many applications human

factors must be taken into account in the design process

Man-machine interface )MMI( is very important to be considered in the design process

Human Factors in Engineering Design

Human factors in man-machine relationship have the following formsbull Anthropometric

)Human interaction in static sense dimensions of body)

bull Ergonomic)Human interaction in dynamic sense repeated tasks)

bull Physiological)Human interaction with body characteristics)

bull Psychological)Human interaction with mental activities)

37Human Factors

Man-Machine Interface

38Human Factors

Man-Machine Interface

The Design Engineer can determine the relative importance of human factors in his design

Anthropometric human factors are related to the physical size of humans it is man-machine interaction in static sense

One of the most common problems is that of driver accommodation in automobiles

Some may have experienced difficulties in either getting in or out reaching the controls or adequate visibility

These may have been due to inadequate attention to the nature of the physical dimensions of humans

40Human Factors

Anthropometric Factors

Human Factors41

Ergonomic Factors

Importance when the human operator is involved with the machine in a dynamic sense

A human is required to exert a force or perhaps supply work to the machine

It should be obvious that the effective operation of a machine over long periods of time will depend upon the matching of requirements to human capability

42Human Factors

Ergonomic Factors

Human Factors43

Ergonomic Factors

One simple example is that when the brake operating force is higher than can be normally tolerated The driver will cope with the situation at first but if the brake operation is frequent muscle fatigue will eventually occur and a dangerous situation will develop

The capability for performing mechanical tasks of this type depends upon

The physical ability of the operator The range of movement required The speed of movement The duration of the activity The position of the operator The environmental condition

44Human Factors

Ergonomic Factors

Human Factors45

Physiological Factors

Physiological factors are of concern when the physicochemical characteristics of the body are significant

As far as body functions are concerned these involve the neurological muscular respiratory vascular and sensory systems

The exterior manifestations can be grouped according to the response to various inputs such as

Visual Auditory Tactile kinesthetic and taste senses Environment

Color discrimination is impaired when illumination levels are low and this can lead to unexpected difficulties in comprehension

An associated problem of illumination which has a critical effect on contrast is that of glare and shadow formation These can be controlled by careful design of lighting systems and selection of materials and colors

46Human Factors

Physiological Factors

An excessive level of noise pollution is in fact undesirable for a number of reasons

Leads to degradation of speech intelligibility Will lead to physical damage to the human auditory system Hinders mental activity due to distracting influences Can lead to psychological and mental disorders if sustained

47Human Factors

Physiological Factors

The speech interference level )SIL( is a measure of the destructiveness of noise It is determined by the level of noise in certain frequency bands

High levels of sound intensity cause pain and even physical damage

The usually accepted threshold of pain is at about 05 Wm2

48Human Factors

Physiological Factors

Human Factors49

Psychological Factors

Psychological considerations in human factors analysis are concerned with the mental activity relationship between man and the machine This involves

bull Interpretation of informationbull Motivation and fatiguebull Decision makingbull Aesthetics

Human Factors50

Psychological Factors

These factors are concerned with the manner of presentation to minimize the error of interpretation

The design of visual displays such as control panels instrument panels and other informative displays is a typical example of psychological factors at work

There are a number of principles which have been developed Some of these include 1 Retain the usual method of operation )eg a power switch is ON when the operating lever is DOWN

2 Use digital indicators for precise numerical values with no need for interpretation That is satisfactory only when values are constant or not changing rapidly

3 For time variable readings not requiring high accuracy use moving pointers over a fixed linear or circular scale

51Human Factors

Psychological Factors

Human Factors52

Psychological Factors

4 Arrange control movement to coincide with required direction of instrument pointer movement

5 Color coding on dials are useful in helping to recognize conditions quickly eg green-normal yellow-caution red-danger

The mechanism of the control device should be designed so that )i( Movements are easy )ii( Slackness is eliminated )iii( The operator is aware of a feedback response )iv( The system response is rapid

If this cannot be achieved the controller should incorporate some restriction so that over reaction and instability does not develop

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

5 Training

Definition of TeamA team is a small number of people with complementary

skills who are committed to a common purpose performance goals and approach for which

they are mutually accountable )Katzenbach and Smith 1993(A team differs from a group in that it is united by a common

function and set of goals

Best Teams

1 A team functions best if there is a shared vision a shared problem statement a goal that all team members can support in other words a pre-determined

objective that everyone agrees upon2 A champion will greatly improve the chance of team success A champion is an individual so committed to the project that they will make sure that nothing

falls through the crackshellip3 A successful team must have

bullcompetence -- skills appropriate to the project or ready access to those skillsbulltrust -- trust develops from team members getting to know what they can expect

of one anotherbullvelocity -- jargon for the ability to make decisions and take action quickly

4 All projects have three kinds of risk which must be assessed and dealt withtechnical -- is the project technically doableorganizational -- do the relevant managers support the projectpersonal -- is your heart in it

Team RolesThere are nine team roles defined to help the team function more effectively

Organizer ndash a person who visualizes and plans for the whole design process

Motivator ndash a person who takes care of the schedule and goals of the teamPusher ndash an active person who makes team work fasterSolver ndash an imaginative person who deals mainly with problem resolutionGatherer ndash a person who is good at collecting information and

communicating with other teamsListener ndash a perceptive person who can listen and combine the ideas and

statements of othersCompleter ndash a careful person who specializes in eliminating design defectsSpecialist ndash a dedicated person who is extremely skilled and has a lot of

knowledge in a specific areaEvaluator ndash a person who has good strategic skills keeps the balance

between immediate needs and long-term goals and weighs consequences

Five Characteristics of TeamworkThere are five characteristics that are the keys to a winning team The following characteristics are arranged in order of importance from highest to lowest1 Shared ValuesTeam members establish shared values and common goals and make the commitment to succeed2 Mutual TrustTeam members trust each other to get the job done They understand their role on the team is important and to put forth maximum effort to fulfill their promisesEveryone should express their opinions feelings and doubts Share information with your team This will help everyone to understand the project in greater detailTeam members should be enthusiastic with each other This will help produce the best performance as a team3 Inspiring VisionProvides direction and motivates the teamTeam members understand what needs to be done and how it can be doneThe focus should be on exceeding customer satisfaction The team should be inspired to work hard so that the products performance quality and cost are all rated excellent4 Skill TalentA team is stronger when team members are skilled in their discipline In addition when people are from different backgrounds they can work as a team to solve complex problemsA skilled individual is important however it is not as important as an individual who is a better team member A good team member prioritizes the values of the team trust on the team and the vision of the team5 Rewards Team members should be rewarded for their hard work and determination Rewards include going

out to eat a bonus or a promotionAs a manager it is your job to give positive reinforcement to your team members People feel good when

people show their appreciation for their contributions

Human Factors

As is well known Engineering Design is concerned with the satisfaction of human needs With this in mind it is quite obvious that there are many areas in which human factors must be taken into account in the design analysis The basic consideration in determining whether or not human factors are important is the possibility of a direct man-machine relationship Having determined the possibility and extent of involvement it is then necessary to consider the form of this relationship be it Anthropometric Ergonomic

Engineering Design is concerned with the satisfaction of human needs

In many applications human

factors must be taken into account in the design process

Man-machine interface )MMI( is very important to be considered in the design process

Human Factors in Engineering Design

Human factors in man-machine relationship have the following formsbull Anthropometric

)Human interaction in static sense dimensions of body)

bull Ergonomic)Human interaction in dynamic sense repeated tasks)

bull Physiological)Human interaction with body characteristics)

bull Psychological)Human interaction with mental activities)

37Human Factors

Man-Machine Interface

38Human Factors

Man-Machine Interface

The Design Engineer can determine the relative importance of human factors in his design

Anthropometric human factors are related to the physical size of humans it is man-machine interaction in static sense

One of the most common problems is that of driver accommodation in automobiles

Some may have experienced difficulties in either getting in or out reaching the controls or adequate visibility

These may have been due to inadequate attention to the nature of the physical dimensions of humans

40Human Factors

Anthropometric Factors

Human Factors41

Ergonomic Factors

Importance when the human operator is involved with the machine in a dynamic sense

A human is required to exert a force or perhaps supply work to the machine

It should be obvious that the effective operation of a machine over long periods of time will depend upon the matching of requirements to human capability

42Human Factors

Ergonomic Factors

Human Factors43

Ergonomic Factors

One simple example is that when the brake operating force is higher than can be normally tolerated The driver will cope with the situation at first but if the brake operation is frequent muscle fatigue will eventually occur and a dangerous situation will develop

The capability for performing mechanical tasks of this type depends upon

The physical ability of the operator The range of movement required The speed of movement The duration of the activity The position of the operator The environmental condition

44Human Factors

Ergonomic Factors

Human Factors45

Physiological Factors

Physiological factors are of concern when the physicochemical characteristics of the body are significant

As far as body functions are concerned these involve the neurological muscular respiratory vascular and sensory systems

The exterior manifestations can be grouped according to the response to various inputs such as

Visual Auditory Tactile kinesthetic and taste senses Environment

Color discrimination is impaired when illumination levels are low and this can lead to unexpected difficulties in comprehension

An associated problem of illumination which has a critical effect on contrast is that of glare and shadow formation These can be controlled by careful design of lighting systems and selection of materials and colors

46Human Factors

Physiological Factors

An excessive level of noise pollution is in fact undesirable for a number of reasons

Leads to degradation of speech intelligibility Will lead to physical damage to the human auditory system Hinders mental activity due to distracting influences Can lead to psychological and mental disorders if sustained

47Human Factors

Physiological Factors

The speech interference level )SIL( is a measure of the destructiveness of noise It is determined by the level of noise in certain frequency bands

High levels of sound intensity cause pain and even physical damage

The usually accepted threshold of pain is at about 05 Wm2

48Human Factors

Physiological Factors

Human Factors49

Psychological Factors

Psychological considerations in human factors analysis are concerned with the mental activity relationship between man and the machine This involves

bull Interpretation of informationbull Motivation and fatiguebull Decision makingbull Aesthetics

Human Factors50

Psychological Factors

These factors are concerned with the manner of presentation to minimize the error of interpretation

The design of visual displays such as control panels instrument panels and other informative displays is a typical example of psychological factors at work

There are a number of principles which have been developed Some of these include 1 Retain the usual method of operation )eg a power switch is ON when the operating lever is DOWN

2 Use digital indicators for precise numerical values with no need for interpretation That is satisfactory only when values are constant or not changing rapidly

3 For time variable readings not requiring high accuracy use moving pointers over a fixed linear or circular scale

51Human Factors

Psychological Factors

Human Factors52

Psychological Factors

4 Arrange control movement to coincide with required direction of instrument pointer movement

5 Color coding on dials are useful in helping to recognize conditions quickly eg green-normal yellow-caution red-danger

The mechanism of the control device should be designed so that )i( Movements are easy )ii( Slackness is eliminated )iii( The operator is aware of a feedback response )iv( The system response is rapid

If this cannot be achieved the controller should incorporate some restriction so that over reaction and instability does not develop

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

Definition of TeamA team is a small number of people with complementary

skills who are committed to a common purpose performance goals and approach for which

they are mutually accountable )Katzenbach and Smith 1993(A team differs from a group in that it is united by a common

function and set of goals

Best Teams

1 A team functions best if there is a shared vision a shared problem statement a goal that all team members can support in other words a pre-determined

objective that everyone agrees upon2 A champion will greatly improve the chance of team success A champion is an individual so committed to the project that they will make sure that nothing

falls through the crackshellip3 A successful team must have

bullcompetence -- skills appropriate to the project or ready access to those skillsbulltrust -- trust develops from team members getting to know what they can expect

of one anotherbullvelocity -- jargon for the ability to make decisions and take action quickly

4 All projects have three kinds of risk which must be assessed and dealt withtechnical -- is the project technically doableorganizational -- do the relevant managers support the projectpersonal -- is your heart in it

Team RolesThere are nine team roles defined to help the team function more effectively

Organizer ndash a person who visualizes and plans for the whole design process

Motivator ndash a person who takes care of the schedule and goals of the teamPusher ndash an active person who makes team work fasterSolver ndash an imaginative person who deals mainly with problem resolutionGatherer ndash a person who is good at collecting information and

communicating with other teamsListener ndash a perceptive person who can listen and combine the ideas and

statements of othersCompleter ndash a careful person who specializes in eliminating design defectsSpecialist ndash a dedicated person who is extremely skilled and has a lot of

knowledge in a specific areaEvaluator ndash a person who has good strategic skills keeps the balance

between immediate needs and long-term goals and weighs consequences

Five Characteristics of TeamworkThere are five characteristics that are the keys to a winning team The following characteristics are arranged in order of importance from highest to lowest1 Shared ValuesTeam members establish shared values and common goals and make the commitment to succeed2 Mutual TrustTeam members trust each other to get the job done They understand their role on the team is important and to put forth maximum effort to fulfill their promisesEveryone should express their opinions feelings and doubts Share information with your team This will help everyone to understand the project in greater detailTeam members should be enthusiastic with each other This will help produce the best performance as a team3 Inspiring VisionProvides direction and motivates the teamTeam members understand what needs to be done and how it can be doneThe focus should be on exceeding customer satisfaction The team should be inspired to work hard so that the products performance quality and cost are all rated excellent4 Skill TalentA team is stronger when team members are skilled in their discipline In addition when people are from different backgrounds they can work as a team to solve complex problemsA skilled individual is important however it is not as important as an individual who is a better team member A good team member prioritizes the values of the team trust on the team and the vision of the team5 Rewards Team members should be rewarded for their hard work and determination Rewards include going

out to eat a bonus or a promotionAs a manager it is your job to give positive reinforcement to your team members People feel good when

people show their appreciation for their contributions

Human Factors

As is well known Engineering Design is concerned with the satisfaction of human needs With this in mind it is quite obvious that there are many areas in which human factors must be taken into account in the design analysis The basic consideration in determining whether or not human factors are important is the possibility of a direct man-machine relationship Having determined the possibility and extent of involvement it is then necessary to consider the form of this relationship be it Anthropometric Ergonomic

Engineering Design is concerned with the satisfaction of human needs

In many applications human

factors must be taken into account in the design process

Man-machine interface )MMI( is very important to be considered in the design process

Human Factors in Engineering Design

Human factors in man-machine relationship have the following formsbull Anthropometric

)Human interaction in static sense dimensions of body)

bull Ergonomic)Human interaction in dynamic sense repeated tasks)

bull Physiological)Human interaction with body characteristics)

bull Psychological)Human interaction with mental activities)

37Human Factors

Man-Machine Interface

38Human Factors

Man-Machine Interface

The Design Engineer can determine the relative importance of human factors in his design

Anthropometric human factors are related to the physical size of humans it is man-machine interaction in static sense

One of the most common problems is that of driver accommodation in automobiles

Some may have experienced difficulties in either getting in or out reaching the controls or adequate visibility

These may have been due to inadequate attention to the nature of the physical dimensions of humans

40Human Factors

Anthropometric Factors

Human Factors41

Ergonomic Factors

Importance when the human operator is involved with the machine in a dynamic sense

A human is required to exert a force or perhaps supply work to the machine

It should be obvious that the effective operation of a machine over long periods of time will depend upon the matching of requirements to human capability

42Human Factors

Ergonomic Factors

Human Factors43

Ergonomic Factors

One simple example is that when the brake operating force is higher than can be normally tolerated The driver will cope with the situation at first but if the brake operation is frequent muscle fatigue will eventually occur and a dangerous situation will develop

The capability for performing mechanical tasks of this type depends upon

The physical ability of the operator The range of movement required The speed of movement The duration of the activity The position of the operator The environmental condition

44Human Factors

Ergonomic Factors

Human Factors45

Physiological Factors

Physiological factors are of concern when the physicochemical characteristics of the body are significant

As far as body functions are concerned these involve the neurological muscular respiratory vascular and sensory systems

The exterior manifestations can be grouped according to the response to various inputs such as

Visual Auditory Tactile kinesthetic and taste senses Environment

Color discrimination is impaired when illumination levels are low and this can lead to unexpected difficulties in comprehension

An associated problem of illumination which has a critical effect on contrast is that of glare and shadow formation These can be controlled by careful design of lighting systems and selection of materials and colors

46Human Factors

Physiological Factors

An excessive level of noise pollution is in fact undesirable for a number of reasons

Leads to degradation of speech intelligibility Will lead to physical damage to the human auditory system Hinders mental activity due to distracting influences Can lead to psychological and mental disorders if sustained

47Human Factors

Physiological Factors

The speech interference level )SIL( is a measure of the destructiveness of noise It is determined by the level of noise in certain frequency bands

High levels of sound intensity cause pain and even physical damage

The usually accepted threshold of pain is at about 05 Wm2

48Human Factors

Physiological Factors

Human Factors49

Psychological Factors

Psychological considerations in human factors analysis are concerned with the mental activity relationship between man and the machine This involves

bull Interpretation of informationbull Motivation and fatiguebull Decision makingbull Aesthetics

Human Factors50

Psychological Factors

These factors are concerned with the manner of presentation to minimize the error of interpretation

The design of visual displays such as control panels instrument panels and other informative displays is a typical example of psychological factors at work

There are a number of principles which have been developed Some of these include 1 Retain the usual method of operation )eg a power switch is ON when the operating lever is DOWN

2 Use digital indicators for precise numerical values with no need for interpretation That is satisfactory only when values are constant or not changing rapidly

3 For time variable readings not requiring high accuracy use moving pointers over a fixed linear or circular scale

51Human Factors

Psychological Factors

Human Factors52

Psychological Factors

4 Arrange control movement to coincide with required direction of instrument pointer movement

5 Color coding on dials are useful in helping to recognize conditions quickly eg green-normal yellow-caution red-danger

The mechanism of the control device should be designed so that )i( Movements are easy )ii( Slackness is eliminated )iii( The operator is aware of a feedback response )iv( The system response is rapid

If this cannot be achieved the controller should incorporate some restriction so that over reaction and instability does not develop

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

Definition of TeamA team is a small number of people with complementary

skills who are committed to a common purpose performance goals and approach for which

they are mutually accountable )Katzenbach and Smith 1993(A team differs from a group in that it is united by a common

function and set of goals

Best Teams

1 A team functions best if there is a shared vision a shared problem statement a goal that all team members can support in other words a pre-determined

objective that everyone agrees upon2 A champion will greatly improve the chance of team success A champion is an individual so committed to the project that they will make sure that nothing

falls through the crackshellip3 A successful team must have

bullcompetence -- skills appropriate to the project or ready access to those skillsbulltrust -- trust develops from team members getting to know what they can expect

of one anotherbullvelocity -- jargon for the ability to make decisions and take action quickly

4 All projects have three kinds of risk which must be assessed and dealt withtechnical -- is the project technically doableorganizational -- do the relevant managers support the projectpersonal -- is your heart in it

Team RolesThere are nine team roles defined to help the team function more effectively

Organizer ndash a person who visualizes and plans for the whole design process

Motivator ndash a person who takes care of the schedule and goals of the teamPusher ndash an active person who makes team work fasterSolver ndash an imaginative person who deals mainly with problem resolutionGatherer ndash a person who is good at collecting information and

communicating with other teamsListener ndash a perceptive person who can listen and combine the ideas and

statements of othersCompleter ndash a careful person who specializes in eliminating design defectsSpecialist ndash a dedicated person who is extremely skilled and has a lot of

knowledge in a specific areaEvaluator ndash a person who has good strategic skills keeps the balance

between immediate needs and long-term goals and weighs consequences

Five Characteristics of TeamworkThere are five characteristics that are the keys to a winning team The following characteristics are arranged in order of importance from highest to lowest1 Shared ValuesTeam members establish shared values and common goals and make the commitment to succeed2 Mutual TrustTeam members trust each other to get the job done They understand their role on the team is important and to put forth maximum effort to fulfill their promisesEveryone should express their opinions feelings and doubts Share information with your team This will help everyone to understand the project in greater detailTeam members should be enthusiastic with each other This will help produce the best performance as a team3 Inspiring VisionProvides direction and motivates the teamTeam members understand what needs to be done and how it can be doneThe focus should be on exceeding customer satisfaction The team should be inspired to work hard so that the products performance quality and cost are all rated excellent4 Skill TalentA team is stronger when team members are skilled in their discipline In addition when people are from different backgrounds they can work as a team to solve complex problemsA skilled individual is important however it is not as important as an individual who is a better team member A good team member prioritizes the values of the team trust on the team and the vision of the team5 Rewards Team members should be rewarded for their hard work and determination Rewards include going

out to eat a bonus or a promotionAs a manager it is your job to give positive reinforcement to your team members People feel good when

people show their appreciation for their contributions

Human Factors

As is well known Engineering Design is concerned with the satisfaction of human needs With this in mind it is quite obvious that there are many areas in which human factors must be taken into account in the design analysis The basic consideration in determining whether or not human factors are important is the possibility of a direct man-machine relationship Having determined the possibility and extent of involvement it is then necessary to consider the form of this relationship be it Anthropometric Ergonomic

Engineering Design is concerned with the satisfaction of human needs

In many applications human

factors must be taken into account in the design process

Man-machine interface )MMI( is very important to be considered in the design process

Human Factors in Engineering Design

Human factors in man-machine relationship have the following formsbull Anthropometric

)Human interaction in static sense dimensions of body)

bull Ergonomic)Human interaction in dynamic sense repeated tasks)

bull Physiological)Human interaction with body characteristics)

bull Psychological)Human interaction with mental activities)

37Human Factors

Man-Machine Interface

38Human Factors

Man-Machine Interface

The Design Engineer can determine the relative importance of human factors in his design

Anthropometric human factors are related to the physical size of humans it is man-machine interaction in static sense

One of the most common problems is that of driver accommodation in automobiles

Some may have experienced difficulties in either getting in or out reaching the controls or adequate visibility

These may have been due to inadequate attention to the nature of the physical dimensions of humans

40Human Factors

Anthropometric Factors

Human Factors41

Ergonomic Factors

Importance when the human operator is involved with the machine in a dynamic sense

A human is required to exert a force or perhaps supply work to the machine

It should be obvious that the effective operation of a machine over long periods of time will depend upon the matching of requirements to human capability

42Human Factors

Ergonomic Factors

Human Factors43

Ergonomic Factors

One simple example is that when the brake operating force is higher than can be normally tolerated The driver will cope with the situation at first but if the brake operation is frequent muscle fatigue will eventually occur and a dangerous situation will develop

The capability for performing mechanical tasks of this type depends upon

The physical ability of the operator The range of movement required The speed of movement The duration of the activity The position of the operator The environmental condition

44Human Factors

Ergonomic Factors

Human Factors45

Physiological Factors

Physiological factors are of concern when the physicochemical characteristics of the body are significant

As far as body functions are concerned these involve the neurological muscular respiratory vascular and sensory systems

The exterior manifestations can be grouped according to the response to various inputs such as

Visual Auditory Tactile kinesthetic and taste senses Environment

Color discrimination is impaired when illumination levels are low and this can lead to unexpected difficulties in comprehension

An associated problem of illumination which has a critical effect on contrast is that of glare and shadow formation These can be controlled by careful design of lighting systems and selection of materials and colors

46Human Factors

Physiological Factors

An excessive level of noise pollution is in fact undesirable for a number of reasons

Leads to degradation of speech intelligibility Will lead to physical damage to the human auditory system Hinders mental activity due to distracting influences Can lead to psychological and mental disorders if sustained

47Human Factors

Physiological Factors

The speech interference level )SIL( is a measure of the destructiveness of noise It is determined by the level of noise in certain frequency bands

High levels of sound intensity cause pain and even physical damage

The usually accepted threshold of pain is at about 05 Wm2

48Human Factors

Physiological Factors

Human Factors49

Psychological Factors

Psychological considerations in human factors analysis are concerned with the mental activity relationship between man and the machine This involves

bull Interpretation of informationbull Motivation and fatiguebull Decision makingbull Aesthetics

Human Factors50

Psychological Factors

These factors are concerned with the manner of presentation to minimize the error of interpretation

The design of visual displays such as control panels instrument panels and other informative displays is a typical example of psychological factors at work

There are a number of principles which have been developed Some of these include 1 Retain the usual method of operation )eg a power switch is ON when the operating lever is DOWN

2 Use digital indicators for precise numerical values with no need for interpretation That is satisfactory only when values are constant or not changing rapidly

3 For time variable readings not requiring high accuracy use moving pointers over a fixed linear or circular scale

51Human Factors

Psychological Factors

Human Factors52

Psychological Factors

4 Arrange control movement to coincide with required direction of instrument pointer movement

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

4 Five Characteristics of Teamwork

5 Training

Definition of TeamA team is a small number of people with complementary

skills who are committed to a common purpose performance goals and approach for which

they are mutually accountable )Katzenbach and Smith 1993(A team differs from a group in that it is united by a common

function and set of goals

Best Teams

1 A team functions best if there is a shared vision a shared problem statement a goal that all team members can support in other words a pre-determined

objective that everyone agrees upon2 A champion will greatly improve the chance of team success A champion is an individual so committed to the project that they will make sure that nothing

falls through the crackshellip3 A successful team must have

bullcompetence -- skills appropriate to the project or ready access to those skillsbulltrust -- trust develops from team members getting to know what they can expect

of one anotherbullvelocity -- jargon for the ability to make decisions and take action quickly

4 All projects have three kinds of risk which must be assessed and dealt withtechnical -- is the project technically doableorganizational -- do the relevant managers support the projectpersonal -- is your heart in it

Team RolesThere are nine team roles defined to help the team function more effectively

Organizer ndash a person who visualizes and plans for the whole design process

Motivator ndash a person who takes care of the schedule and goals of the teamPusher ndash an active person who makes team work fasterSolver ndash an imaginative person who deals mainly with problem resolutionGatherer ndash a person who is good at collecting information and

communicating with other teamsListener ndash a perceptive person who can listen and combine the ideas and

statements of othersCompleter ndash a careful person who specializes in eliminating design defectsSpecialist ndash a dedicated person who is extremely skilled and has a lot of

knowledge in a specific areaEvaluator ndash a person who has good strategic skills keeps the balance

between immediate needs and long-term goals and weighs consequences

Five Characteristics of TeamworkThere are five characteristics that are the keys to a winning team The following characteristics are arranged in order of importance from highest to lowest1 Shared ValuesTeam members establish shared values and common goals and make the commitment to succeed2 Mutual TrustTeam members trust each other to get the job done They understand their role on the team is important and to put forth maximum effort to fulfill their promisesEveryone should express their opinions feelings and doubts Share information with your team This will help everyone to understand the project in greater detailTeam members should be enthusiastic with each other This will help produce the best performance as a team3 Inspiring VisionProvides direction and motivates the teamTeam members understand what needs to be done and how it can be doneThe focus should be on exceeding customer satisfaction The team should be inspired to work hard so that the products performance quality and cost are all rated excellent4 Skill TalentA team is stronger when team members are skilled in their discipline In addition when people are from different backgrounds they can work as a team to solve complex problemsA skilled individual is important however it is not as important as an individual who is a better team member A good team member prioritizes the values of the team trust on the team and the vision of the team5 Rewards Team members should be rewarded for their hard work and determination Rewards include going

out to eat a bonus or a promotionAs a manager it is your job to give positive reinforcement to your team members People feel good when

people show their appreciation for their contributions

Human Factors

As is well known Engineering Design is concerned with the satisfaction of human needs With this in mind it is quite obvious that there are many areas in which human factors must be taken into account in the design analysis The basic consideration in determining whether or not human factors are important is the possibility of a direct man-machine relationship Having determined the possibility and extent of involvement it is then necessary to consider the form of this relationship be it Anthropometric Ergonomic

Physiological Psychological

Engineering Design is concerned with the satisfaction of human needs

In many applications human

factors must be taken into account in the design process

Man-machine interface )MMI( is very important to be considered in the design process

Human Factors in Engineering Design

Human factors in man-machine relationship have the following formsbull Anthropometric

)Human interaction in static sense dimensions of body)

bull Ergonomic)Human interaction in dynamic sense repeated tasks)

bull Physiological)Human interaction with body characteristics)

bull Psychological)Human interaction with mental activities)

37Human Factors

Man-Machine Interface

38Human Factors

Man-Machine Interface

The Design Engineer can determine the relative importance of human factors in his design

Anthropometric human factors are related to the physical size of humans it is man-machine interaction in static sense

One of the most common problems is that of driver accommodation in automobiles

Some may have experienced difficulties in either getting in or out reaching the controls or adequate visibility

These may have been due to inadequate attention to the nature of the physical dimensions of humans

40Human Factors

Anthropometric Factors

Human Factors41

Ergonomic Factors

Importance when the human operator is involved with the machine in a dynamic sense

A human is required to exert a force or perhaps supply work to the machine

It should be obvious that the effective operation of a machine over long periods of time will depend upon the matching of requirements to human capability

42Human Factors

Ergonomic Factors

Human Factors43

Ergonomic Factors

One simple example is that when the brake operating force is higher than can be normally tolerated The driver will cope with the situation at first but if the brake operation is frequent muscle fatigue will eventually occur and a dangerous situation will develop

The capability for performing mechanical tasks of this type depends upon

The physical ability of the operator The range of movement required The speed of movement The duration of the activity The position of the operator The environmental condition

44Human Factors

Ergonomic Factors

Human Factors45

Physiological Factors

Physiological factors are of concern when the physicochemical characteristics of the body are significant

As far as body functions are concerned these involve the neurological muscular respiratory vascular and sensory systems

The exterior manifestations can be grouped according to the response to various inputs such as

Visual Auditory Tactile kinesthetic and taste senses Environment

Color discrimination is impaired when illumination levels are low and this can lead to unexpected difficulties in comprehension

An associated problem of illumination which has a critical effect on contrast is that of glare and shadow formation These can be controlled by careful design of lighting systems and selection of materials and colors

46Human Factors

Physiological Factors

An excessive level of noise pollution is in fact undesirable for a number of reasons

Leads to degradation of speech intelligibility Will lead to physical damage to the human auditory system Hinders mental activity due to distracting influences Can lead to psychological and mental disorders if sustained

47Human Factors

Physiological Factors

The speech interference level )SIL( is a measure of the destructiveness of noise It is determined by the level of noise in certain frequency bands

High levels of sound intensity cause pain and even physical damage

The usually accepted threshold of pain is at about 05 Wm2

48Human Factors

Physiological Factors

Human Factors49

Psychological Factors

Psychological considerations in human factors analysis are concerned with the mental activity relationship between man and the machine This involves

bull Interpretation of informationbull Motivation and fatiguebull Decision makingbull Aesthetics

Human Factors50

Psychological Factors

These factors are concerned with the manner of presentation to minimize the error of interpretation

The design of visual displays such as control panels instrument panels and other informative displays is a typical example of psychological factors at work

There are a number of principles which have been developed Some of these include 1 Retain the usual method of operation )eg a power switch is ON when the operating lever is DOWN

2 Use digital indicators for precise numerical values with no need for interpretation That is satisfactory only when values are constant or not changing rapidly

3 For time variable readings not requiring high accuracy use moving pointers over a fixed linear or circular scale

51Human Factors

Psychological Factors

Human Factors52

Psychological Factors

4 Arrange control movement to coincide with required direction of instrument pointer movement

5 Color coding on dials are useful in helping to recognize conditions quickly eg green-normal yellow-caution red-danger

The mechanism of the control device should be designed so that )i( Movements are easy )ii( Slackness is eliminated )iii( The operator is aware of a feedback response )iv( The system response is rapid

If this cannot be achieved the controller should incorporate some restriction so that over reaction and instability does not develop

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

4 Five Characteristics of Teamwork

5 Training

Definition of TeamA team is a small number of people with complementary

skills who are committed to a common purpose performance goals and approach for which

they are mutually accountable )Katzenbach and Smith 1993(A team differs from a group in that it is united by a common

function and set of goals

Best Teams

1 A team functions best if there is a shared vision a shared problem statement a goal that all team members can support in other words a pre-determined

objective that everyone agrees upon2 A champion will greatly improve the chance of team success A champion is an individual so committed to the project that they will make sure that nothing

falls through the crackshellip3 A successful team must have

bullcompetence -- skills appropriate to the project or ready access to those skillsbulltrust -- trust develops from team members getting to know what they can expect

of one anotherbullvelocity -- jargon for the ability to make decisions and take action quickly

4 All projects have three kinds of risk which must be assessed and dealt withtechnical -- is the project technically doableorganizational -- do the relevant managers support the projectpersonal -- is your heart in it

Team RolesThere are nine team roles defined to help the team function more effectively

Organizer ndash a person who visualizes and plans for the whole design process

Motivator ndash a person who takes care of the schedule and goals of the teamPusher ndash an active person who makes team work fasterSolver ndash an imaginative person who deals mainly with problem resolutionGatherer ndash a person who is good at collecting information and

communicating with other teamsListener ndash a perceptive person who can listen and combine the ideas and

statements of othersCompleter ndash a careful person who specializes in eliminating design defectsSpecialist ndash a dedicated person who is extremely skilled and has a lot of

knowledge in a specific areaEvaluator ndash a person who has good strategic skills keeps the balance

between immediate needs and long-term goals and weighs consequences

Five Characteristics of TeamworkThere are five characteristics that are the keys to a winning team The following characteristics are arranged in order of importance from highest to lowest1 Shared ValuesTeam members establish shared values and common goals and make the commitment to succeed2 Mutual TrustTeam members trust each other to get the job done They understand their role on the team is important and to put forth maximum effort to fulfill their promisesEveryone should express their opinions feelings and doubts Share information with your team This will help everyone to understand the project in greater detailTeam members should be enthusiastic with each other This will help produce the best performance as a team3 Inspiring VisionProvides direction and motivates the teamTeam members understand what needs to be done and how it can be doneThe focus should be on exceeding customer satisfaction The team should be inspired to work hard so that the products performance quality and cost are all rated excellent4 Skill TalentA team is stronger when team members are skilled in their discipline In addition when people are from different backgrounds they can work as a team to solve complex problemsA skilled individual is important however it is not as important as an individual who is a better team member A good team member prioritizes the values of the team trust on the team and the vision of the team5 Rewards Team members should be rewarded for their hard work and determination Rewards include going

out to eat a bonus or a promotionAs a manager it is your job to give positive reinforcement to your team members People feel good when

people show their appreciation for their contributions

Human Factors

As is well known Engineering Design is concerned with the satisfaction of human needs With this in mind it is quite obvious that there are many areas in which human factors must be taken into account in the design analysis The basic consideration in determining whether or not human factors are important is the possibility of a direct man-machine relationship Having determined the possibility and extent of involvement it is then necessary to consider the form of this relationship be it Anthropometric Ergonomic

Physiological Psychological

Engineering Design is concerned with the satisfaction of human needs

In many applications human

factors must be taken into account in the design process

Man-machine interface )MMI( is very important to be considered in the design process

Human Factors in Engineering Design

Human factors in man-machine relationship have the following formsbull Anthropometric

)Human interaction in static sense dimensions of body)

bull Ergonomic)Human interaction in dynamic sense repeated tasks)

bull Physiological)Human interaction with body characteristics)

bull Psychological)Human interaction with mental activities)

37Human Factors

Man-Machine Interface

38Human Factors

Man-Machine Interface

The Design Engineer can determine the relative importance of human factors in his design

Anthropometric human factors are related to the physical size of humans it is man-machine interaction in static sense

One of the most common problems is that of driver accommodation in automobiles

Some may have experienced difficulties in either getting in or out reaching the controls or adequate visibility

These may have been due to inadequate attention to the nature of the physical dimensions of humans

40Human Factors

Anthropometric Factors

Human Factors41

Ergonomic Factors

Importance when the human operator is involved with the machine in a dynamic sense

A human is required to exert a force or perhaps supply work to the machine

It should be obvious that the effective operation of a machine over long periods of time will depend upon the matching of requirements to human capability

42Human Factors

Ergonomic Factors

Human Factors43

Ergonomic Factors

One simple example is that when the brake operating force is higher than can be normally tolerated The driver will cope with the situation at first but if the brake operation is frequent muscle fatigue will eventually occur and a dangerous situation will develop

The capability for performing mechanical tasks of this type depends upon

The physical ability of the operator The range of movement required The speed of movement The duration of the activity The position of the operator The environmental condition

44Human Factors

Ergonomic Factors

Human Factors45

Physiological Factors

Physiological factors are of concern when the physicochemical characteristics of the body are significant

As far as body functions are concerned these involve the neurological muscular respiratory vascular and sensory systems

The exterior manifestations can be grouped according to the response to various inputs such as

Visual Auditory Tactile kinesthetic and taste senses Environment

Color discrimination is impaired when illumination levels are low and this can lead to unexpected difficulties in comprehension

An associated problem of illumination which has a critical effect on contrast is that of glare and shadow formation These can be controlled by careful design of lighting systems and selection of materials and colors

46Human Factors

Physiological Factors

An excessive level of noise pollution is in fact undesirable for a number of reasons

Leads to degradation of speech intelligibility Will lead to physical damage to the human auditory system Hinders mental activity due to distracting influences Can lead to psychological and mental disorders if sustained

47Human Factors

Physiological Factors

The speech interference level )SIL( is a measure of the destructiveness of noise It is determined by the level of noise in certain frequency bands

High levels of sound intensity cause pain and even physical damage

The usually accepted threshold of pain is at about 05 Wm2

48Human Factors

Physiological Factors

Human Factors49

Psychological Factors

Psychological considerations in human factors analysis are concerned with the mental activity relationship between man and the machine This involves

bull Interpretation of informationbull Motivation and fatiguebull Decision makingbull Aesthetics

Human Factors50

Psychological Factors

These factors are concerned with the manner of presentation to minimize the error of interpretation

The design of visual displays such as control panels instrument panels and other informative displays is a typical example of psychological factors at work

There are a number of principles which have been developed Some of these include 1 Retain the usual method of operation )eg a power switch is ON when the operating lever is DOWN

2 Use digital indicators for precise numerical values with no need for interpretation That is satisfactory only when values are constant or not changing rapidly

3 For time variable readings not requiring high accuracy use moving pointers over a fixed linear or circular scale

51Human Factors

Psychological Factors

Human Factors52

Psychological Factors

4 Arrange control movement to coincide with required direction of instrument pointer movement

5 Color coding on dials are useful in helping to recognize conditions quickly eg green-normal yellow-caution red-danger

The mechanism of the control device should be designed so that )i( Movements are easy )ii( Slackness is eliminated )iii( The operator is aware of a feedback response )iv( The system response is rapid

If this cannot be achieved the controller should incorporate some restriction so that over reaction and instability does not develop

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

4 Five Characteristics of Teamwork

5 Training

Definition of TeamA team is a small number of people with complementary

skills who are committed to a common purpose performance goals and approach for which

they are mutually accountable )Katzenbach and Smith 1993(A team differs from a group in that it is united by a common

function and set of goals

Best Teams

1 A team functions best if there is a shared vision a shared problem statement a goal that all team members can support in other words a pre-determined

objective that everyone agrees upon2 A champion will greatly improve the chance of team success A champion is an individual so committed to the project that they will make sure that nothing

falls through the crackshellip3 A successful team must have

bullcompetence -- skills appropriate to the project or ready access to those skillsbulltrust -- trust develops from team members getting to know what they can expect

of one anotherbullvelocity -- jargon for the ability to make decisions and take action quickly

4 All projects have three kinds of risk which must be assessed and dealt withtechnical -- is the project technically doableorganizational -- do the relevant managers support the projectpersonal -- is your heart in it

Team RolesThere are nine team roles defined to help the team function more effectively

Organizer ndash a person who visualizes and plans for the whole design process

Motivator ndash a person who takes care of the schedule and goals of the teamPusher ndash an active person who makes team work fasterSolver ndash an imaginative person who deals mainly with problem resolutionGatherer ndash a person who is good at collecting information and

communicating with other teamsListener ndash a perceptive person who can listen and combine the ideas and

statements of othersCompleter ndash a careful person who specializes in eliminating design defectsSpecialist ndash a dedicated person who is extremely skilled and has a lot of

knowledge in a specific areaEvaluator ndash a person who has good strategic skills keeps the balance

between immediate needs and long-term goals and weighs consequences

Five Characteristics of TeamworkThere are five characteristics that are the keys to a winning team The following characteristics are arranged in order of importance from highest to lowest1 Shared ValuesTeam members establish shared values and common goals and make the commitment to succeed2 Mutual TrustTeam members trust each other to get the job done They understand their role on the team is important and to put forth maximum effort to fulfill their promisesEveryone should express their opinions feelings and doubts Share information with your team This will help everyone to understand the project in greater detailTeam members should be enthusiastic with each other This will help produce the best performance as a team3 Inspiring VisionProvides direction and motivates the teamTeam members understand what needs to be done and how it can be doneThe focus should be on exceeding customer satisfaction The team should be inspired to work hard so that the products performance quality and cost are all rated excellent4 Skill TalentA team is stronger when team members are skilled in their discipline In addition when people are from different backgrounds they can work as a team to solve complex problemsA skilled individual is important however it is not as important as an individual who is a better team member A good team member prioritizes the values of the team trust on the team and the vision of the team5 Rewards Team members should be rewarded for their hard work and determination Rewards include going

out to eat a bonus or a promotionAs a manager it is your job to give positive reinforcement to your team members People feel good when

people show their appreciation for their contributions

Human Factors

As is well known Engineering Design is concerned with the satisfaction of human needs With this in mind it is quite obvious that there are many areas in which human factors must be taken into account in the design analysis The basic consideration in determining whether or not human factors are important is the possibility of a direct man-machine relationship Having determined the possibility and extent of involvement it is then necessary to consider the form of this relationship be it Anthropometric Ergonomic

Engineering Design is concerned with the satisfaction of human needs

In many applications human

factors must be taken into account in the design process

Man-machine interface )MMI( is very important to be considered in the design process

Human Factors in Engineering Design

Human factors in man-machine relationship have the following formsbull Anthropometric

)Human interaction in static sense dimensions of body)

bull Ergonomic)Human interaction in dynamic sense repeated tasks)

bull Physiological)Human interaction with body characteristics)

bull Psychological)Human interaction with mental activities)

37Human Factors

Man-Machine Interface

38Human Factors

Man-Machine Interface

The Design Engineer can determine the relative importance of human factors in his design

Anthropometric human factors are related to the physical size of humans it is man-machine interaction in static sense

One of the most common problems is that of driver accommodation in automobiles

Some may have experienced difficulties in either getting in or out reaching the controls or adequate visibility

These may have been due to inadequate attention to the nature of the physical dimensions of humans

40Human Factors

Anthropometric Factors

Human Factors41

Ergonomic Factors

Importance when the human operator is involved with the machine in a dynamic sense

A human is required to exert a force or perhaps supply work to the machine

It should be obvious that the effective operation of a machine over long periods of time will depend upon the matching of requirements to human capability

42Human Factors

Ergonomic Factors

Human Factors43

Ergonomic Factors

One simple example is that when the brake operating force is higher than can be normally tolerated The driver will cope with the situation at first but if the brake operation is frequent muscle fatigue will eventually occur and a dangerous situation will develop

The capability for performing mechanical tasks of this type depends upon

The physical ability of the operator The range of movement required The speed of movement The duration of the activity The position of the operator The environmental condition

44Human Factors

Ergonomic Factors

Human Factors45

Physiological Factors

Physiological factors are of concern when the physicochemical characteristics of the body are significant

As far as body functions are concerned these involve the neurological muscular respiratory vascular and sensory systems

The exterior manifestations can be grouped according to the response to various inputs such as

Visual Auditory Tactile kinesthetic and taste senses Environment

Color discrimination is impaired when illumination levels are low and this can lead to unexpected difficulties in comprehension

An associated problem of illumination which has a critical effect on contrast is that of glare and shadow formation These can be controlled by careful design of lighting systems and selection of materials and colors

46Human Factors

Physiological Factors

An excessive level of noise pollution is in fact undesirable for a number of reasons

Leads to degradation of speech intelligibility Will lead to physical damage to the human auditory system Hinders mental activity due to distracting influences Can lead to psychological and mental disorders if sustained

47Human Factors

Physiological Factors

The speech interference level )SIL( is a measure of the destructiveness of noise It is determined by the level of noise in certain frequency bands

High levels of sound intensity cause pain and even physical damage

The usually accepted threshold of pain is at about 05 Wm2

48Human Factors

Human Factors49

Psychological Factors

Psychological considerations in human factors analysis are concerned with the mental activity relationship between man and the machine This involves

bull Interpretation of informationbull Motivation and fatiguebull Decision makingbull Aesthetics

Human Factors50

Psychological Factors

These factors are concerned with the manner of presentation to minimize the error of interpretation

The design of visual displays such as control panels instrument panels and other informative displays is a typical example of psychological factors at work

There are a number of principles which have been developed Some of these include 1 Retain the usual method of operation )eg a power switch is ON when the operating lever is DOWN

2 Use digital indicators for precise numerical values with no need for interpretation That is satisfactory only when values are constant or not changing rapidly

3 For time variable readings not requiring high accuracy use moving pointers over a fixed linear or circular scale

51Human Factors

Psychological Factors

Human Factors52

Psychological Factors

4 Arrange control movement to coincide with required direction of instrument pointer movement

5 Color coding on dials are useful in helping to recognize conditions quickly eg green-normal yellow-caution red-danger

The mechanism of the control device should be designed so that )i( Movements are easy )ii( Slackness is eliminated )iii( The operator is aware of a feedback response )iv( The system response is rapid

If this cannot be achieved the controller should incorporate some restriction so that over reaction and instability does not develop

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

4 Five Characteristics of Teamwork

5 Training

Definition of TeamA team is a small number of people with complementary

skills who are committed to a common purpose performance goals and approach for which

they are mutually accountable )Katzenbach and Smith 1993(A team differs from a group in that it is united by a common

function and set of goals

Best Teams

1 A team functions best if there is a shared vision a shared problem statement a goal that all team members can support in other words a pre-determined

objective that everyone agrees upon2 A champion will greatly improve the chance of team success A champion is an individual so committed to the project that they will make sure that nothing

falls through the crackshellip3 A successful team must have

bullcompetence -- skills appropriate to the project or ready access to those skillsbulltrust -- trust develops from team members getting to know what they can expect

of one anotherbullvelocity -- jargon for the ability to make decisions and take action quickly

4 All projects have three kinds of risk which must be assessed and dealt withtechnical -- is the project technically doableorganizational -- do the relevant managers support the projectpersonal -- is your heart in it

Team RolesThere are nine team roles defined to help the team function more effectively

Organizer ndash a person who visualizes and plans for the whole design process

Motivator ndash a person who takes care of the schedule and goals of the teamPusher ndash an active person who makes team work fasterSolver ndash an imaginative person who deals mainly with problem resolutionGatherer ndash a person who is good at collecting information and

communicating with other teamsListener ndash a perceptive person who can listen and combine the ideas and

statements of othersCompleter ndash a careful person who specializes in eliminating design defectsSpecialist ndash a dedicated person who is extremely skilled and has a lot of

knowledge in a specific areaEvaluator ndash a person who has good strategic skills keeps the balance

between immediate needs and long-term goals and weighs consequences

Five Characteristics of TeamworkThere are five characteristics that are the keys to a winning team The following characteristics are arranged in order of importance from highest to lowest1 Shared ValuesTeam members establish shared values and common goals and make the commitment to succeed2 Mutual TrustTeam members trust each other to get the job done They understand their role on the team is important and to put forth maximum effort to fulfill their promisesEveryone should express their opinions feelings and doubts Share information with your team This will help everyone to understand the project in greater detailTeam members should be enthusiastic with each other This will help produce the best performance as a team3 Inspiring VisionProvides direction and motivates the teamTeam members understand what needs to be done and how it can be doneThe focus should be on exceeding customer satisfaction The team should be inspired to work hard so that the products performance quality and cost are all rated excellent4 Skill TalentA team is stronger when team members are skilled in their discipline In addition when people are from different backgrounds they can work as a team to solve complex problemsA skilled individual is important however it is not as important as an individual who is a better team member A good team member prioritizes the values of the team trust on the team and the vision of the team5 Rewards Team members should be rewarded for their hard work and determination Rewards include going

out to eat a bonus or a promotionAs a manager it is your job to give positive reinforcement to your team members People feel good when

people show their appreciation for their contributions

Human Factors

As is well known Engineering Design is concerned with the satisfaction of human needs With this in mind it is quite obvious that there are many areas in which human factors must be taken into account in the design analysis The basic consideration in determining whether or not human factors are important is the possibility of a direct man-machine relationship Having determined the possibility and extent of involvement it is then necessary to consider the form of this relationship be it Anthropometric Ergonomic

Engineering Design is concerned with the satisfaction of human needs

In many applications human

factors must be taken into account in the design process

Man-machine interface )MMI( is very important to be considered in the design process

Human Factors in Engineering Design

Human factors in man-machine relationship have the following formsbull Anthropometric

)Human interaction in static sense dimensions of body)

bull Ergonomic)Human interaction in dynamic sense repeated tasks)

bull Physiological)Human interaction with body characteristics)

bull Psychological)Human interaction with mental activities)

37Human Factors

Man-Machine Interface

38Human Factors

Man-Machine Interface

The Design Engineer can determine the relative importance of human factors in his design

Anthropometric human factors are related to the physical size of humans it is man-machine interaction in static sense

One of the most common problems is that of driver accommodation in automobiles

Some may have experienced difficulties in either getting in or out reaching the controls or adequate visibility

These may have been due to inadequate attention to the nature of the physical dimensions of humans

40Human Factors

Anthropometric Factors

Human Factors41

Ergonomic Factors

Importance when the human operator is involved with the machine in a dynamic sense

A human is required to exert a force or perhaps supply work to the machine

It should be obvious that the effective operation of a machine over long periods of time will depend upon the matching of requirements to human capability

42Human Factors

Ergonomic Factors

Human Factors43

Ergonomic Factors

One simple example is that when the brake operating force is higher than can be normally tolerated The driver will cope with the situation at first but if the brake operation is frequent muscle fatigue will eventually occur and a dangerous situation will develop

The capability for performing mechanical tasks of this type depends upon

The physical ability of the operator The range of movement required The speed of movement The duration of the activity The position of the operator The environmental condition

44Human Factors

Ergonomic Factors

Human Factors45

Physiological Factors

Physiological factors are of concern when the physicochemical characteristics of the body are significant

As far as body functions are concerned these involve the neurological muscular respiratory vascular and sensory systems

The exterior manifestations can be grouped according to the response to various inputs such as

Visual Auditory Tactile kinesthetic and taste senses Environment

Color discrimination is impaired when illumination levels are low and this can lead to unexpected difficulties in comprehension

An associated problem of illumination which has a critical effect on contrast is that of glare and shadow formation These can be controlled by careful design of lighting systems and selection of materials and colors

46Human Factors

Physiological Factors

An excessive level of noise pollution is in fact undesirable for a number of reasons

Leads to degradation of speech intelligibility Will lead to physical damage to the human auditory system Hinders mental activity due to distracting influences Can lead to psychological and mental disorders if sustained

47Human Factors

Physiological Factors

The speech interference level )SIL( is a measure of the destructiveness of noise It is determined by the level of noise in certain frequency bands

High levels of sound intensity cause pain and even physical damage

The usually accepted threshold of pain is at about 05 Wm2

48Human Factors

Physiological Factors

Human Factors49

Psychological Factors

Psychological considerations in human factors analysis are concerned with the mental activity relationship between man and the machine This involves

bull Interpretation of informationbull Motivation and fatiguebull Decision makingbull Aesthetics

Human Factors50

Psychological Factors

These factors are concerned with the manner of presentation to minimize the error of interpretation

The design of visual displays such as control panels instrument panels and other informative displays is a typical example of psychological factors at work

There are a number of principles which have been developed Some of these include 1 Retain the usual method of operation )eg a power switch is ON when the operating lever is DOWN

2 Use digital indicators for precise numerical values with no need for interpretation That is satisfactory only when values are constant or not changing rapidly

3 For time variable readings not requiring high accuracy use moving pointers over a fixed linear or circular scale

51Human Factors

Psychological Factors

Human Factors52

Psychological Factors

4 Arrange control movement to coincide with required direction of instrument pointer movement

5 Color coding on dials are useful in helping to recognize conditions quickly eg green-normal yellow-caution red-danger

The mechanism of the control device should be designed so that )i( Movements are easy )ii( Slackness is eliminated )iii( The operator is aware of a feedback response )iv( The system response is rapid

If this cannot be achieved the controller should incorporate some restriction so that over reaction and instability does not develop

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

4 Five Characteristics of Teamwork

5 Training

Definition of TeamA team is a small number of people with complementary

skills who are committed to a common purpose performance goals and approach for which

they are mutually accountable )Katzenbach and Smith 1993(A team differs from a group in that it is united by a common

function and set of goals

Best Teams

1 A team functions best if there is a shared vision a shared problem statement a goal that all team members can support in other words a pre-determined

objective that everyone agrees upon2 A champion will greatly improve the chance of team success A champion is an individual so committed to the project that they will make sure that nothing

falls through the crackshellip3 A successful team must have

bullcompetence -- skills appropriate to the project or ready access to those skillsbulltrust -- trust develops from team members getting to know what they can expect

of one anotherbullvelocity -- jargon for the ability to make decisions and take action quickly

4 All projects have three kinds of risk which must be assessed and dealt withtechnical -- is the project technically doableorganizational -- do the relevant managers support the projectpersonal -- is your heart in it

Team RolesThere are nine team roles defined to help the team function more effectively

Organizer ndash a person who visualizes and plans for the whole design process

Motivator ndash a person who takes care of the schedule and goals of the teamPusher ndash an active person who makes team work fasterSolver ndash an imaginative person who deals mainly with problem resolutionGatherer ndash a person who is good at collecting information and

communicating with other teamsListener ndash a perceptive person who can listen and combine the ideas and

statements of othersCompleter ndash a careful person who specializes in eliminating design defectsSpecialist ndash a dedicated person who is extremely skilled and has a lot of

knowledge in a specific areaEvaluator ndash a person who has good strategic skills keeps the balance

between immediate needs and long-term goals and weighs consequences

Five Characteristics of TeamworkThere are five characteristics that are the keys to a winning team The following characteristics are arranged in order of importance from highest to lowest1 Shared ValuesTeam members establish shared values and common goals and make the commitment to succeed2 Mutual TrustTeam members trust each other to get the job done They understand their role on the team is important and to put forth maximum effort to fulfill their promisesEveryone should express their opinions feelings and doubts Share information with your team This will help everyone to understand the project in greater detailTeam members should be enthusiastic with each other This will help produce the best performance as a team3 Inspiring VisionProvides direction and motivates the teamTeam members understand what needs to be done and how it can be doneThe focus should be on exceeding customer satisfaction The team should be inspired to work hard so that the products performance quality and cost are all rated excellent4 Skill TalentA team is stronger when team members are skilled in their discipline In addition when people are from different backgrounds they can work as a team to solve complex problemsA skilled individual is important however it is not as important as an individual who is a better team member A good team member prioritizes the values of the team trust on the team and the vision of the team5 Rewards Team members should be rewarded for their hard work and determination Rewards include going

out to eat a bonus or a promotionAs a manager it is your job to give positive reinforcement to your team members People feel good when

people show their appreciation for their contributions

Human Factors

As is well known Engineering Design is concerned with the satisfaction of human needs With this in mind it is quite obvious that there are many areas in which human factors must be taken into account in the design analysis The basic consideration in determining whether or not human factors are important is the possibility of a direct man-machine relationship Having determined the possibility and extent of involvement it is then necessary to consider the form of this relationship be it Anthropometric Ergonomic

Engineering Design is concerned with the satisfaction of human needs

In many applications human

factors must be taken into account in the design process

Man-machine interface )MMI( is very important to be considered in the design process

Human Factors in Engineering Design

Human factors in man-machine relationship have the following formsbull Anthropometric

)Human interaction in static sense dimensions of body)

bull Ergonomic)Human interaction in dynamic sense repeated tasks)

bull Physiological)Human interaction with body characteristics)

bull Psychological)Human interaction with mental activities)

37Human Factors

Man-Machine Interface

38Human Factors

Man-Machine Interface

The Design Engineer can determine the relative importance of human factors in his design

Anthropometric human factors are related to the physical size of humans it is man-machine interaction in static sense

One of the most common problems is that of driver accommodation in automobiles

Some may have experienced difficulties in either getting in or out reaching the controls or adequate visibility

These may have been due to inadequate attention to the nature of the physical dimensions of humans

40Human Factors

Anthropometric Factors

Human Factors41

Ergonomic Factors

Importance when the human operator is involved with the machine in a dynamic sense

A human is required to exert a force or perhaps supply work to the machine

It should be obvious that the effective operation of a machine over long periods of time will depend upon the matching of requirements to human capability

42Human Factors

Ergonomic Factors

Human Factors43

Ergonomic Factors

One simple example is that when the brake operating force is higher than can be normally tolerated The driver will cope with the situation at first but if the brake operation is frequent muscle fatigue will eventually occur and a dangerous situation will develop

The capability for performing mechanical tasks of this type depends upon

The physical ability of the operator The range of movement required The speed of movement The duration of the activity The position of the operator The environmental condition

44Human Factors

Ergonomic Factors

Human Factors45

Physiological Factors

Physiological factors are of concern when the physicochemical characteristics of the body are significant

As far as body functions are concerned these involve the neurological muscular respiratory vascular and sensory systems

The exterior manifestations can be grouped according to the response to various inputs such as

Visual Auditory Tactile kinesthetic and taste senses Environment

Color discrimination is impaired when illumination levels are low and this can lead to unexpected difficulties in comprehension

An associated problem of illumination which has a critical effect on contrast is that of glare and shadow formation These can be controlled by careful design of lighting systems and selection of materials and colors

46Human Factors

Physiological Factors

An excessive level of noise pollution is in fact undesirable for a number of reasons

Leads to degradation of speech intelligibility Will lead to physical damage to the human auditory system Hinders mental activity due to distracting influences Can lead to psychological and mental disorders if sustained

47Human Factors

Physiological Factors

The speech interference level )SIL( is a measure of the destructiveness of noise It is determined by the level of noise in certain frequency bands

High levels of sound intensity cause pain and even physical damage

The usually accepted threshold of pain is at about 05 Wm2

48Human Factors

Human Factors49

Psychological Factors

Psychological considerations in human factors analysis are concerned with the mental activity relationship between man and the machine This involves

bull Interpretation of informationbull Motivation and fatiguebull Decision makingbull Aesthetics

Human Factors50

Psychological Factors

These factors are concerned with the manner of presentation to minimize the error of interpretation

The design of visual displays such as control panels instrument panels and other informative displays is a typical example of psychological factors at work

There are a number of principles which have been developed Some of these include 1 Retain the usual method of operation )eg a power switch is ON when the operating lever is DOWN

2 Use digital indicators for precise numerical values with no need for interpretation That is satisfactory only when values are constant or not changing rapidly

3 For time variable readings not requiring high accuracy use moving pointers over a fixed linear or circular scale

51Human Factors

Psychological Factors

Human Factors52

Psychological Factors

4 Arrange control movement to coincide with required direction of instrument pointer movement

5 Color coding on dials are useful in helping to recognize conditions quickly eg green-normal yellow-caution red-danger

The mechanism of the control device should be designed so that )i( Movements are easy )ii( Slackness is eliminated )iii( The operator is aware of a feedback response )iv( The system response is rapid

If this cannot be achieved the controller should incorporate some restriction so that over reaction and instability does not develop

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

4 Five Characteristics of Teamwork

5 Training

Definition of TeamA team is a small number of people with complementary

skills who are committed to a common purpose performance goals and approach for which

they are mutually accountable )Katzenbach and Smith 1993(A team differs from a group in that it is united by a common

function and set of goals

Best Teams

1 A team functions best if there is a shared vision a shared problem statement a goal that all team members can support in other words a pre-determined

objective that everyone agrees upon2 A champion will greatly improve the chance of team success A champion is an individual so committed to the project that they will make sure that nothing

falls through the crackshellip3 A successful team must have

bullcompetence -- skills appropriate to the project or ready access to those skillsbulltrust -- trust develops from team members getting to know what they can expect

of one anotherbullvelocity -- jargon for the ability to make decisions and take action quickly

4 All projects have three kinds of risk which must be assessed and dealt withtechnical -- is the project technically doableorganizational -- do the relevant managers support the projectpersonal -- is your heart in it

Team RolesThere are nine team roles defined to help the team function more effectively

Organizer ndash a person who visualizes and plans for the whole design process

Motivator ndash a person who takes care of the schedule and goals of the teamPusher ndash an active person who makes team work fasterSolver ndash an imaginative person who deals mainly with problem resolutionGatherer ndash a person who is good at collecting information and

communicating with other teamsListener ndash a perceptive person who can listen and combine the ideas and

statements of othersCompleter ndash a careful person who specializes in eliminating design defectsSpecialist ndash a dedicated person who is extremely skilled and has a lot of

knowledge in a specific areaEvaluator ndash a person who has good strategic skills keeps the balance

between immediate needs and long-term goals and weighs consequences

Five Characteristics of TeamworkThere are five characteristics that are the keys to a winning team The following characteristics are arranged in order of importance from highest to lowest1 Shared ValuesTeam members establish shared values and common goals and make the commitment to succeed2 Mutual TrustTeam members trust each other to get the job done They understand their role on the team is important and to put forth maximum effort to fulfill their promisesEveryone should express their opinions feelings and doubts Share information with your team This will help everyone to understand the project in greater detailTeam members should be enthusiastic with each other This will help produce the best performance as a team3 Inspiring VisionProvides direction and motivates the teamTeam members understand what needs to be done and how it can be doneThe focus should be on exceeding customer satisfaction The team should be inspired to work hard so that the products performance quality and cost are all rated excellent4 Skill TalentA team is stronger when team members are skilled in their discipline In addition when people are from different backgrounds they can work as a team to solve complex problemsA skilled individual is important however it is not as important as an individual who is a better team member A good team member prioritizes the values of the team trust on the team and the vision of the team5 Rewards Team members should be rewarded for their hard work and determination Rewards include going

out to eat a bonus or a promotionAs a manager it is your job to give positive reinforcement to your team members People feel good when

people show their appreciation for their contributions

Human Factors

As is well known Engineering Design is concerned with the satisfaction of human needs With this in mind it is quite obvious that there are many areas in which human factors must be taken into account in the design analysis The basic consideration in determining whether or not human factors are important is the possibility of a direct man-machine relationship Having determined the possibility and extent of involvement it is then necessary to consider the form of this relationship be it Anthropometric Ergonomic

Engineering Design is concerned with the satisfaction of human needs

In many applications human

factors must be taken into account in the design process

Man-machine interface )MMI( is very important to be considered in the design process

Human Factors in Engineering Design

Human factors in man-machine relationship have the following formsbull Anthropometric

)Human interaction in static sense dimensions of body)

bull Ergonomic)Human interaction in dynamic sense repeated tasks)

bull Physiological)Human interaction with body characteristics)

bull Psychological)Human interaction with mental activities)

37Human Factors

Man-Machine Interface

38Human Factors

Man-Machine Interface

The Design Engineer can determine the relative importance of human factors in his design

Anthropometric human factors are related to the physical size of humans it is man-machine interaction in static sense

One of the most common problems is that of driver accommodation in automobiles

Some may have experienced difficulties in either getting in or out reaching the controls or adequate visibility

These may have been due to inadequate attention to the nature of the physical dimensions of humans

40Human Factors

Anthropometric Factors

Human Factors41

Ergonomic Factors

Importance when the human operator is involved with the machine in a dynamic sense

A human is required to exert a force or perhaps supply work to the machine

It should be obvious that the effective operation of a machine over long periods of time will depend upon the matching of requirements to human capability

42Human Factors

Ergonomic Factors

Human Factors43

Ergonomic Factors

One simple example is that when the brake operating force is higher than can be normally tolerated The driver will cope with the situation at first but if the brake operation is frequent muscle fatigue will eventually occur and a dangerous situation will develop

The capability for performing mechanical tasks of this type depends upon

The physical ability of the operator The range of movement required The speed of movement The duration of the activity The position of the operator The environmental condition

44Human Factors

Ergonomic Factors

Human Factors45

Physiological Factors

Physiological factors are of concern when the physicochemical characteristics of the body are significant

As far as body functions are concerned these involve the neurological muscular respiratory vascular and sensory systems

The exterior manifestations can be grouped according to the response to various inputs such as

Visual Auditory Tactile kinesthetic and taste senses Environment

Color discrimination is impaired when illumination levels are low and this can lead to unexpected difficulties in comprehension

An associated problem of illumination which has a critical effect on contrast is that of glare and shadow formation These can be controlled by careful design of lighting systems and selection of materials and colors

46Human Factors

Physiological Factors

An excessive level of noise pollution is in fact undesirable for a number of reasons

Leads to degradation of speech intelligibility Will lead to physical damage to the human auditory system Hinders mental activity due to distracting influences Can lead to psychological and mental disorders if sustained

47Human Factors

Physiological Factors

The speech interference level )SIL( is a measure of the destructiveness of noise It is determined by the level of noise in certain frequency bands

High levels of sound intensity cause pain and even physical damage

The usually accepted threshold of pain is at about 05 Wm2

48Human Factors

Human Factors49

Psychological Factors

Psychological considerations in human factors analysis are concerned with the mental activity relationship between man and the machine This involves

bull Interpretation of informationbull Motivation and fatiguebull Decision makingbull Aesthetics

Human Factors50

Psychological Factors

These factors are concerned with the manner of presentation to minimize the error of interpretation

The design of visual displays such as control panels instrument panels and other informative displays is a typical example of psychological factors at work

There are a number of principles which have been developed Some of these include 1 Retain the usual method of operation )eg a power switch is ON when the operating lever is DOWN

2 Use digital indicators for precise numerical values with no need for interpretation That is satisfactory only when values are constant or not changing rapidly

3 For time variable readings not requiring high accuracy use moving pointers over a fixed linear or circular scale

51Human Factors

Human Factors52

Psychological Factors

4 Arrange control movement to coincide with required direction of instrument pointer movement

5 Color coding on dials are useful in helping to recognize conditions quickly eg green-normal yellow-caution red-danger

The mechanism of the control device should be designed so that )i( Movements are easy )ii( Slackness is eliminated )iii( The operator is aware of a feedback response )iv( The system response is rapid

If this cannot be achieved the controller should incorporate some restriction so that over reaction and instability does not develop

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

4 Five Characteristics of Teamwork

5 Training

Definition of TeamA team is a small number of people with complementary

skills who are committed to a common purpose performance goals and approach for which

they are mutually accountable )Katzenbach and Smith 1993(A team differs from a group in that it is united by a common

function and set of goals

Best Teams

1 A team functions best if there is a shared vision a shared problem statement a goal that all team members can support in other words a pre-determined

objective that everyone agrees upon2 A champion will greatly improve the chance of team success A champion is an individual so committed to the project that they will make sure that nothing

falls through the crackshellip3 A successful team must have

bullcompetence -- skills appropriate to the project or ready access to those skillsbulltrust -- trust develops from team members getting to know what they can expect

of one anotherbullvelocity -- jargon for the ability to make decisions and take action quickly

4 All projects have three kinds of risk which must be assessed and dealt withtechnical -- is the project technically doableorganizational -- do the relevant managers support the projectpersonal -- is your heart in it

Team RolesThere are nine team roles defined to help the team function more effectively

Organizer ndash a person who visualizes and plans for the whole design process

Motivator ndash a person who takes care of the schedule and goals of the teamPusher ndash an active person who makes team work fasterSolver ndash an imaginative person who deals mainly with problem resolutionGatherer ndash a person who is good at collecting information and

communicating with other teamsListener ndash a perceptive person who can listen and combine the ideas and

statements of othersCompleter ndash a careful person who specializes in eliminating design defectsSpecialist ndash a dedicated person who is extremely skilled and has a lot of

knowledge in a specific areaEvaluator ndash a person who has good strategic skills keeps the balance

between immediate needs and long-term goals and weighs consequences

Five Characteristics of TeamworkThere are five characteristics that are the keys to a winning team The following characteristics are arranged in order of importance from highest to lowest1 Shared ValuesTeam members establish shared values and common goals and make the commitment to succeed2 Mutual TrustTeam members trust each other to get the job done They understand their role on the team is important and to put forth maximum effort to fulfill their promisesEveryone should express their opinions feelings and doubts Share information with your team This will help everyone to understand the project in greater detailTeam members should be enthusiastic with each other This will help produce the best performance as a team3 Inspiring VisionProvides direction and motivates the teamTeam members understand what needs to be done and how it can be doneThe focus should be on exceeding customer satisfaction The team should be inspired to work hard so that the products performance quality and cost are all rated excellent4 Skill TalentA team is stronger when team members are skilled in their discipline In addition when people are from different backgrounds they can work as a team to solve complex problemsA skilled individual is important however it is not as important as an individual who is a better team member A good team member prioritizes the values of the team trust on the team and the vision of the team5 Rewards Team members should be rewarded for their hard work and determination Rewards include going

out to eat a bonus or a promotionAs a manager it is your job to give positive reinforcement to your team members People feel good when

people show their appreciation for their contributions

Human Factors

As is well known Engineering Design is concerned with the satisfaction of human needs With this in mind it is quite obvious that there are many areas in which human factors must be taken into account in the design analysis The basic consideration in determining whether or not human factors are important is the possibility of a direct man-machine relationship Having determined the possibility and extent of involvement it is then necessary to consider the form of this relationship be it Anthropometric Ergonomic

Physiological Psychological

Engineering Design is concerned with the satisfaction of human needs

In many applications human

factors must be taken into account in the design process

Man-machine interface )MMI( is very important to be considered in the design process

Human Factors in Engineering Design

Human factors in man-machine relationship have the following formsbull Anthropometric

)Human interaction in static sense dimensions of body)

bull Ergonomic)Human interaction in dynamic sense repeated tasks)

bull Physiological)Human interaction with body characteristics)

bull Psychological)Human interaction with mental activities)

37Human Factors

Man-Machine Interface

38Human Factors

Man-Machine Interface

The Design Engineer can determine the relative importance of human factors in his design

Anthropometric human factors are related to the physical size of humans it is man-machine interaction in static sense

One of the most common problems is that of driver accommodation in automobiles

Some may have experienced difficulties in either getting in or out reaching the controls or adequate visibility

These may have been due to inadequate attention to the nature of the physical dimensions of humans

40Human Factors

Anthropometric Factors

Human Factors41

Ergonomic Factors

Importance when the human operator is involved with the machine in a dynamic sense

A human is required to exert a force or perhaps supply work to the machine

It should be obvious that the effective operation of a machine over long periods of time will depend upon the matching of requirements to human capability

42Human Factors

Ergonomic Factors

Human Factors43

Ergonomic Factors

One simple example is that when the brake operating force is higher than can be normally tolerated The driver will cope with the situation at first but if the brake operation is frequent muscle fatigue will eventually occur and a dangerous situation will develop

The capability for performing mechanical tasks of this type depends upon

The physical ability of the operator The range of movement required The speed of movement The duration of the activity The position of the operator The environmental condition

44Human Factors

Ergonomic Factors

Human Factors45

Physiological Factors

Physiological factors are of concern when the physicochemical characteristics of the body are significant

As far as body functions are concerned these involve the neurological muscular respiratory vascular and sensory systems

The exterior manifestations can be grouped according to the response to various inputs such as

Visual Auditory Tactile kinesthetic and taste senses Environment

Color discrimination is impaired when illumination levels are low and this can lead to unexpected difficulties in comprehension

An associated problem of illumination which has a critical effect on contrast is that of glare and shadow formation These can be controlled by careful design of lighting systems and selection of materials and colors

46Human Factors

Physiological Factors

An excessive level of noise pollution is in fact undesirable for a number of reasons

Leads to degradation of speech intelligibility Will lead to physical damage to the human auditory system Hinders mental activity due to distracting influences Can lead to psychological and mental disorders if sustained

47Human Factors

Physiological Factors

The speech interference level )SIL( is a measure of the destructiveness of noise It is determined by the level of noise in certain frequency bands

High levels of sound intensity cause pain and even physical damage

The usually accepted threshold of pain is at about 05 Wm2

48Human Factors

Physiological Factors

Human Factors49

Psychological Factors

Psychological considerations in human factors analysis are concerned with the mental activity relationship between man and the machine This involves

bull Interpretation of informationbull Motivation and fatiguebull Decision makingbull Aesthetics

Human Factors50

Psychological Factors

These factors are concerned with the manner of presentation to minimize the error of interpretation

The design of visual displays such as control panels instrument panels and other informative displays is a typical example of psychological factors at work

There are a number of principles which have been developed Some of these include 1 Retain the usual method of operation )eg a power switch is ON when the operating lever is DOWN

2 Use digital indicators for precise numerical values with no need for interpretation That is satisfactory only when values are constant or not changing rapidly

3 For time variable readings not requiring high accuracy use moving pointers over a fixed linear or circular scale

51Human Factors

Psychological Factors

Human Factors52

Psychological Factors

4 Arrange control movement to coincide with required direction of instrument pointer movement

5 Color coding on dials are useful in helping to recognize conditions quickly eg green-normal yellow-caution red-danger

The mechanism of the control device should be designed so that )i( Movements are easy )ii( Slackness is eliminated )iii( The operator is aware of a feedback response )iv( The system response is rapid

If this cannot be achieved the controller should incorporate some restriction so that over reaction and instability does not develop

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

4 Five Characteristics of Teamwork

5 Training

Definition of TeamA team is a small number of people with complementary

skills who are committed to a common purpose performance goals and approach for which

they are mutually accountable )Katzenbach and Smith 1993(A team differs from a group in that it is united by a common

function and set of goals

Best Teams

1 A team functions best if there is a shared vision a shared problem statement a goal that all team members can support in other words a pre-determined

objective that everyone agrees upon2 A champion will greatly improve the chance of team success A champion is an individual so committed to the project that they will make sure that nothing

falls through the crackshellip3 A successful team must have

bullcompetence -- skills appropriate to the project or ready access to those skillsbulltrust -- trust develops from team members getting to know what they can expect

of one anotherbullvelocity -- jargon for the ability to make decisions and take action quickly

4 All projects have three kinds of risk which must be assessed and dealt withtechnical -- is the project technically doableorganizational -- do the relevant managers support the projectpersonal -- is your heart in it

Team RolesThere are nine team roles defined to help the team function more effectively

Organizer ndash a person who visualizes and plans for the whole design process

Motivator ndash a person who takes care of the schedule and goals of the teamPusher ndash an active person who makes team work fasterSolver ndash an imaginative person who deals mainly with problem resolutionGatherer ndash a person who is good at collecting information and

communicating with other teamsListener ndash a perceptive person who can listen and combine the ideas and

statements of othersCompleter ndash a careful person who specializes in eliminating design defectsSpecialist ndash a dedicated person who is extremely skilled and has a lot of

knowledge in a specific areaEvaluator ndash a person who has good strategic skills keeps the balance

between immediate needs and long-term goals and weighs consequences

Five Characteristics of TeamworkThere are five characteristics that are the keys to a winning team The following characteristics are arranged in order of importance from highest to lowest1 Shared ValuesTeam members establish shared values and common goals and make the commitment to succeed2 Mutual TrustTeam members trust each other to get the job done They understand their role on the team is important and to put forth maximum effort to fulfill their promisesEveryone should express their opinions feelings and doubts Share information with your team This will help everyone to understand the project in greater detailTeam members should be enthusiastic with each other This will help produce the best performance as a team3 Inspiring VisionProvides direction and motivates the teamTeam members understand what needs to be done and how it can be doneThe focus should be on exceeding customer satisfaction The team should be inspired to work hard so that the products performance quality and cost are all rated excellent4 Skill TalentA team is stronger when team members are skilled in their discipline In addition when people are from different backgrounds they can work as a team to solve complex problemsA skilled individual is important however it is not as important as an individual who is a better team member A good team member prioritizes the values of the team trust on the team and the vision of the team5 Rewards Team members should be rewarded for their hard work and determination Rewards include going

out to eat a bonus or a promotionAs a manager it is your job to give positive reinforcement to your team members People feel good when

people show their appreciation for their contributions

Human Factors

As is well known Engineering Design is concerned with the satisfaction of human needs With this in mind it is quite obvious that there are many areas in which human factors must be taken into account in the design analysis The basic consideration in determining whether or not human factors are important is the possibility of a direct man-machine relationship Having determined the possibility and extent of involvement it is then necessary to consider the form of this relationship be it Anthropometric Ergonomic

Physiological Psychological

Engineering Design is concerned with the satisfaction of human needs

In many applications human

factors must be taken into account in the design process

Man-machine interface )MMI( is very important to be considered in the design process

Human Factors in Engineering Design

Human factors in man-machine relationship have the following formsbull Anthropometric

)Human interaction in static sense dimensions of body)

bull Ergonomic)Human interaction in dynamic sense repeated tasks)

bull Physiological)Human interaction with body characteristics)

bull Psychological)Human interaction with mental activities)

37Human Factors

Man-Machine Interface

38Human Factors

Man-Machine Interface

The Design Engineer can determine the relative importance of human factors in his design

Anthropometric human factors are related to the physical size of humans it is man-machine interaction in static sense

One of the most common problems is that of driver accommodation in automobiles

Some may have experienced difficulties in either getting in or out reaching the controls or adequate visibility

These may have been due to inadequate attention to the nature of the physical dimensions of humans

40Human Factors

Anthropometric Factors

Human Factors41

Ergonomic Factors

Importance when the human operator is involved with the machine in a dynamic sense

A human is required to exert a force or perhaps supply work to the machine

It should be obvious that the effective operation of a machine over long periods of time will depend upon the matching of requirements to human capability

42Human Factors

Ergonomic Factors

Human Factors43

Ergonomic Factors

One simple example is that when the brake operating force is higher than can be normally tolerated The driver will cope with the situation at first but if the brake operation is frequent muscle fatigue will eventually occur and a dangerous situation will develop

The capability for performing mechanical tasks of this type depends upon

The physical ability of the operator The range of movement required The speed of movement The duration of the activity The position of the operator The environmental condition

44Human Factors

Ergonomic Factors

Human Factors45

Physiological Factors

Physiological factors are of concern when the physicochemical characteristics of the body are significant

As far as body functions are concerned these involve the neurological muscular respiratory vascular and sensory systems

The exterior manifestations can be grouped according to the response to various inputs such as

Visual Auditory Tactile kinesthetic and taste senses Environment

Color discrimination is impaired when illumination levels are low and this can lead to unexpected difficulties in comprehension

An associated problem of illumination which has a critical effect on contrast is that of glare and shadow formation These can be controlled by careful design of lighting systems and selection of materials and colors

46Human Factors

Physiological Factors

An excessive level of noise pollution is in fact undesirable for a number of reasons

Leads to degradation of speech intelligibility Will lead to physical damage to the human auditory system Hinders mental activity due to distracting influences Can lead to psychological and mental disorders if sustained

47Human Factors

Physiological Factors

The speech interference level )SIL( is a measure of the destructiveness of noise It is determined by the level of noise in certain frequency bands

High levels of sound intensity cause pain and even physical damage

The usually accepted threshold of pain is at about 05 Wm2

48Human Factors

Physiological Factors

Human Factors49

Psychological Factors

Psychological considerations in human factors analysis are concerned with the mental activity relationship between man and the machine This involves

bull Interpretation of informationbull Motivation and fatiguebull Decision makingbull Aesthetics

Human Factors50

Psychological Factors

These factors are concerned with the manner of presentation to minimize the error of interpretation

The design of visual displays such as control panels instrument panels and other informative displays is a typical example of psychological factors at work

There are a number of principles which have been developed Some of these include 1 Retain the usual method of operation )eg a power switch is ON when the operating lever is DOWN

2 Use digital indicators for precise numerical values with no need for interpretation That is satisfactory only when values are constant or not changing rapidly

3 For time variable readings not requiring high accuracy use moving pointers over a fixed linear or circular scale

51Human Factors

Psychological Factors

Human Factors52

Psychological Factors

4 Arrange control movement to coincide with required direction of instrument pointer movement

5 Color coding on dials are useful in helping to recognize conditions quickly eg green-normal yellow-caution red-danger

The mechanism of the control device should be designed so that )i( Movements are easy )ii( Slackness is eliminated )iii( The operator is aware of a feedback response )iv( The system response is rapid

If this cannot be achieved the controller should incorporate some restriction so that over reaction and instability does not develop

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

Definition of TeamA team is a small number of people with complementary

skills who are committed to a common purpose performance goals and approach for which

they are mutually accountable )Katzenbach and Smith 1993(A team differs from a group in that it is united by a common

function and set of goals

Best Teams

1 A team functions best if there is a shared vision a shared problem statement a goal that all team members can support in other words a pre-determined

objective that everyone agrees upon2 A champion will greatly improve the chance of team success A champion is an individual so committed to the project that they will make sure that nothing

falls through the crackshellip3 A successful team must have

bullcompetence -- skills appropriate to the project or ready access to those skillsbulltrust -- trust develops from team members getting to know what they can expect

of one anotherbullvelocity -- jargon for the ability to make decisions and take action quickly

4 All projects have three kinds of risk which must be assessed and dealt withtechnical -- is the project technically doableorganizational -- do the relevant managers support the projectpersonal -- is your heart in it

Team RolesThere are nine team roles defined to help the team function more effectively

Organizer ndash a person who visualizes and plans for the whole design process

Motivator ndash a person who takes care of the schedule and goals of the teamPusher ndash an active person who makes team work fasterSolver ndash an imaginative person who deals mainly with problem resolutionGatherer ndash a person who is good at collecting information and

communicating with other teamsListener ndash a perceptive person who can listen and combine the ideas and

statements of othersCompleter ndash a careful person who specializes in eliminating design defectsSpecialist ndash a dedicated person who is extremely skilled and has a lot of

knowledge in a specific areaEvaluator ndash a person who has good strategic skills keeps the balance

between immediate needs and long-term goals and weighs consequences

Five Characteristics of TeamworkThere are five characteristics that are the keys to a winning team The following characteristics are arranged in order of importance from highest to lowest1 Shared ValuesTeam members establish shared values and common goals and make the commitment to succeed2 Mutual TrustTeam members trust each other to get the job done They understand their role on the team is important and to put forth maximum effort to fulfill their promisesEveryone should express their opinions feelings and doubts Share information with your team This will help everyone to understand the project in greater detailTeam members should be enthusiastic with each other This will help produce the best performance as a team3 Inspiring VisionProvides direction and motivates the teamTeam members understand what needs to be done and how it can be doneThe focus should be on exceeding customer satisfaction The team should be inspired to work hard so that the products performance quality and cost are all rated excellent4 Skill TalentA team is stronger when team members are skilled in their discipline In addition when people are from different backgrounds they can work as a team to solve complex problemsA skilled individual is important however it is not as important as an individual who is a better team member A good team member prioritizes the values of the team trust on the team and the vision of the team5 Rewards Team members should be rewarded for their hard work and determination Rewards include going

out to eat a bonus or a promotionAs a manager it is your job to give positive reinforcement to your team members People feel good when

people show their appreciation for their contributions

Human Factors

As is well known Engineering Design is concerned with the satisfaction of human needs With this in mind it is quite obvious that there are many areas in which human factors must be taken into account in the design analysis The basic consideration in determining whether or not human factors are important is the possibility of a direct man-machine relationship Having determined the possibility and extent of involvement it is then necessary to consider the form of this relationship be it Anthropometric Ergonomic

Physiological Psychological

Engineering Design is concerned with the satisfaction of human needs

In many applications human

factors must be taken into account in the design process

Man-machine interface )MMI( is very important to be considered in the design process

Human Factors in Engineering Design

Human factors in man-machine relationship have the following formsbull Anthropometric

)Human interaction in static sense dimensions of body)

bull Ergonomic)Human interaction in dynamic sense repeated tasks)

bull Physiological)Human interaction with body characteristics)

bull Psychological)Human interaction with mental activities)

37Human Factors

Man-Machine Interface

38Human Factors

Man-Machine Interface

The Design Engineer can determine the relative importance of human factors in his design

Anthropometric human factors are related to the physical size of humans it is man-machine interaction in static sense

One of the most common problems is that of driver accommodation in automobiles

Some may have experienced difficulties in either getting in or out reaching the controls or adequate visibility

These may have been due to inadequate attention to the nature of the physical dimensions of humans

40Human Factors

Anthropometric Factors

Human Factors41

Ergonomic Factors

Importance when the human operator is involved with the machine in a dynamic sense

A human is required to exert a force or perhaps supply work to the machine

It should be obvious that the effective operation of a machine over long periods of time will depend upon the matching of requirements to human capability

42Human Factors

Ergonomic Factors

Human Factors43

Ergonomic Factors

One simple example is that when the brake operating force is higher than can be normally tolerated The driver will cope with the situation at first but if the brake operation is frequent muscle fatigue will eventually occur and a dangerous situation will develop

The capability for performing mechanical tasks of this type depends upon

The physical ability of the operator The range of movement required The speed of movement The duration of the activity The position of the operator The environmental condition

44Human Factors

Ergonomic Factors

Human Factors45

Physiological Factors

Physiological factors are of concern when the physicochemical characteristics of the body are significant

As far as body functions are concerned these involve the neurological muscular respiratory vascular and sensory systems

The exterior manifestations can be grouped according to the response to various inputs such as

Visual Auditory Tactile kinesthetic and taste senses Environment

Color discrimination is impaired when illumination levels are low and this can lead to unexpected difficulties in comprehension

An associated problem of illumination which has a critical effect on contrast is that of glare and shadow formation These can be controlled by careful design of lighting systems and selection of materials and colors

46Human Factors

Physiological Factors

An excessive level of noise pollution is in fact undesirable for a number of reasons

Leads to degradation of speech intelligibility Will lead to physical damage to the human auditory system Hinders mental activity due to distracting influences Can lead to psychological and mental disorders if sustained

47Human Factors

Physiological Factors

The speech interference level )SIL( is a measure of the destructiveness of noise It is determined by the level of noise in certain frequency bands

High levels of sound intensity cause pain and even physical damage

The usually accepted threshold of pain is at about 05 Wm2

48Human Factors

Physiological Factors

Human Factors49

Psychological Factors

Psychological considerations in human factors analysis are concerned with the mental activity relationship between man and the machine This involves

bull Interpretation of informationbull Motivation and fatiguebull Decision makingbull Aesthetics

Human Factors50

Psychological Factors

These factors are concerned with the manner of presentation to minimize the error of interpretation

The design of visual displays such as control panels instrument panels and other informative displays is a typical example of psychological factors at work

There are a number of principles which have been developed Some of these include 1 Retain the usual method of operation )eg a power switch is ON when the operating lever is DOWN

2 Use digital indicators for precise numerical values with no need for interpretation That is satisfactory only when values are constant or not changing rapidly

3 For time variable readings not requiring high accuracy use moving pointers over a fixed linear or circular scale

51Human Factors

Psychological Factors

Human Factors52

Psychological Factors

4 Arrange control movement to coincide with required direction of instrument pointer movement

5 Color coding on dials are useful in helping to recognize conditions quickly eg green-normal yellow-caution red-danger

The mechanism of the control device should be designed so that )i( Movements are easy )ii( Slackness is eliminated )iii( The operator is aware of a feedback response )iv( The system response is rapid

If this cannot be achieved the controller should incorporate some restriction so that over reaction and instability does not develop

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

Five Characteristics of TeamworkThere are five characteristics that are the keys to a winning team The following characteristics are arranged in order of importance from highest to lowest1 Shared ValuesTeam members establish shared values and common goals and make the commitment to succeed2 Mutual TrustTeam members trust each other to get the job done They understand their role on the team is important and to put forth maximum effort to fulfill their promisesEveryone should express their opinions feelings and doubts Share information with your team This will help everyone to understand the project in greater detailTeam members should be enthusiastic with each other This will help produce the best performance as a team3 Inspiring VisionProvides direction and motivates the teamTeam members understand what needs to be done and how it can be doneThe focus should be on exceeding customer satisfaction The team should be inspired to work hard so that the products performance quality and cost are all rated excellent4 Skill TalentA team is stronger when team members are skilled in their discipline In addition when people are from different backgrounds they can work as a team to solve complex problemsA skilled individual is important however it is not as important as an individual who is a better team member A good team member prioritizes the values of the team trust on the team and the vision of the team5 Rewards Team members should be rewarded for their hard work and determination Rewards include going

out to eat a bonus or a promotionAs a manager it is your job to give positive reinforcement to your team members People feel good when

people show their appreciation for their contributions

Human Factors

As is well known Engineering Design is concerned with the satisfaction of human needs With this in mind it is quite obvious that there are many areas in which human factors must be taken into account in the design analysis The basic consideration in determining whether or not human factors are important is the possibility of a direct man-machine relationship Having determined the possibility and extent of involvement it is then necessary to consider the form of this relationship be it Anthropometric Ergonomic

Engineering Design is concerned with the satisfaction of human needs

In many applications human

factors must be taken into account in the design process

Man-machine interface )MMI( is very important to be considered in the design process

Human Factors in Engineering Design

Human factors in man-machine relationship have the following formsbull Anthropometric

)Human interaction in static sense dimensions of body)

bull Ergonomic)Human interaction in dynamic sense repeated tasks)

bull Physiological)Human interaction with body characteristics)

bull Psychological)Human interaction with mental activities)

Man-Machine Interface

The Design Engineer can determine the relative importance of human factors in his design

Anthropometric human factors are related to the physical size of humans it is man-machine interaction in static sense

One of the most common problems is that of driver accommodation in automobiles

Some may have experienced difficulties in either getting in or out reaching the controls or adequate visibility

These may have been due to inadequate attention to the nature of the physical dimensions of humans

Ergonomic Factors

Importance when the human operator is involved with the machine in a dynamic sense

A human is required to exert a force or perhaps supply work to the machine

It should be obvious that the effective operation of a machine over long periods of time will depend upon the matching of requirements to human capability

Ergonomic Factors

One simple example is that when the brake operating force is higher than can be normally tolerated The driver will cope with the situation at first but if the brake operation is frequent muscle fatigue will eventually occur and a dangerous situation will develop

The capability for performing mechanical tasks of this type depends upon

The physical ability of the operator The range of movement required The speed of movement The duration of the activity The position of the operator The environmental condition

44Human Factors

Ergonomic Factors

Human Factors45

Physiological Factors

Physiological factors are of concern when the physicochemical characteristics of the body are significant

As far as body functions are concerned these involve the neurological muscular respiratory vascular and sensory systems

The exterior manifestations can be grouped according to the response to various inputs such as

Visual Auditory Tactile kinesthetic and taste senses Environment

Color discrimination is impaired when illumination levels are low and this can lead to unexpected difficulties in comprehension

An associated problem of illumination which has a critical effect on contrast is that of glare and shadow formation These can be controlled by careful design of lighting systems and selection of materials and colors

46Human Factors

Physiological Factors

An excessive level of noise pollution is in fact undesirable for a number of reasons

Leads to degradation of speech intelligibility Will lead to physical damage to the human auditory system Hinders mental activity due to distracting influences Can lead to psychological and mental disorders if sustained

47Human Factors

Physiological Factors

The speech interference level )SIL( is a measure of the destructiveness of noise It is determined by the level of noise in certain frequency bands

High levels of sound intensity cause pain and even physical damage

The usually accepted threshold of pain is at about 05 Wm2

Psychological Factors

Psychological considerations in human factors analysis are concerned with the mental activity relationship between man and the machine This involves

bull Interpretation of informationbull Motivation and fatiguebull Decision makingbull Aesthetics

Human Factors50

Psychological Factors

These factors are concerned with the manner of presentation to minimize the error of interpretation

The design of visual displays such as control panels instrument panels and other informative displays is a typical example of psychological factors at work

There are a number of principles which have been developed Some of these include 1 Retain the usual method of operation )eg a power switch is ON when the operating lever is DOWN

2 Use digital indicators for precise numerical values with no need for interpretation That is satisfactory only when values are constant or not changing rapidly

3 For time variable readings not requiring high accuracy use moving pointers over a fixed linear or circular scale

4 Arrange control movement to coincide with required direction of instrument pointer movement

5 Color coding on dials are useful in helping to recognize conditions quickly eg green-normal yellow-caution red-danger

The mechanism of the control device should be designed so that )i( Movements are easy )ii( Slackness is eliminated )iii( The operator is aware of a feedback response )iv( The system response is rapid

If this cannot be achieved the controller should incorporate some restriction so that over reaction and instability does not develop

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

Definition of TeamA team is a small number of people with complementary

skills who are committed to a common purpose performance goals and approach for which

they are mutually accountable )Katzenbach and Smith 1993(A team differs from a group in that it is united by a common

function and set of goals

Best Teams

1 A team functions best if there is a shared vision a shared problem statement a goal that all team members can support in other words a pre-determined

objective that everyone agrees upon2 A champion will greatly improve the chance of team success A champion is an individual so committed to the project that they will make sure that nothing

falls through the crackshellip3 A successful team must have

bullcompetence -- skills appropriate to the project or ready access to those skillsbulltrust -- trust develops from team members getting to know what they can expect

of one anotherbullvelocity -- jargon for the ability to make decisions and take action quickly

4 All projects have three kinds of risk which must be assessed and dealt withtechnical -- is the project technically doableorganizational -- do the relevant managers support the projectpersonal -- is your heart in it

Team RolesThere are nine team roles defined to help the team function more effectively

Organizer ndash a person who visualizes and plans for the whole design process

Motivator ndash a person who takes care of the schedule and goals of the teamPusher ndash an active person who makes team work fasterSolver ndash an imaginative person who deals mainly with problem resolutionGatherer ndash a person who is good at collecting information and

communicating with other teamsListener ndash a perceptive person who can listen and combine the ideas and

statements of othersCompleter ndash a careful person who specializes in eliminating design defectsSpecialist ndash a dedicated person who is extremely skilled and has a lot of

knowledge in a specific areaEvaluator ndash a person who has good strategic skills keeps the balance

between immediate needs and long-term goals and weighs consequences

Five Characteristics of TeamworkThere are five characteristics that are the keys to a winning team The following characteristics are arranged in order of importance from highest to lowest1 Shared ValuesTeam members establish shared values and common goals and make the commitment to succeed2 Mutual TrustTeam members trust each other to get the job done They understand their role on the team is important and to put forth maximum effort to fulfill their promisesEveryone should express their opinions feelings and doubts Share information with your team This will help everyone to understand the project in greater detailTeam members should be enthusiastic with each other This will help produce the best performance as a team3 Inspiring VisionProvides direction and motivates the teamTeam members understand what needs to be done and how it can be doneThe focus should be on exceeding customer satisfaction The team should be inspired to work hard so that the products performance quality and cost are all rated excellent4 Skill TalentA team is stronger when team members are skilled in their discipline In addition when people are from different backgrounds they can work as a team to solve complex problemsA skilled individual is important however it is not as important as an individual who is a better team member A good team member prioritizes the values of the team trust on the team and the vision of the team5 Rewards Team members should be rewarded for their hard work and determination Rewards include going

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

Best Teams

1 A team functions best if there is a shared vision a shared problem statement a goal that all team members can support in other words a pre-determined

objective that everyone agrees upon2 A champion will greatly improve the chance of team success A champion is an individual so committed to the project that they will make sure that nothing

falls through the crackshellip3 A successful team must have

bullcompetence -- skills appropriate to the project or ready access to those skillsbulltrust -- trust develops from team members getting to know what they can expect

of one anotherbullvelocity -- jargon for the ability to make decisions and take action quickly

4 All projects have three kinds of risk which must be assessed and dealt withtechnical -- is the project technically doableorganizational -- do the relevant managers support the projectpersonal -- is your heart in it

Team RolesThere are nine team roles defined to help the team function more effectively

Organizer ndash a person who visualizes and plans for the whole design process

Motivator ndash a person who takes care of the schedule and goals of the teamPusher ndash an active person who makes team work fasterSolver ndash an imaginative person who deals mainly with problem resolutionGatherer ndash a person who is good at collecting information and

communicating with other teamsListener ndash a perceptive person who can listen and combine the ideas and

statements of othersCompleter ndash a careful person who specializes in eliminating design defectsSpecialist ndash a dedicated person who is extremely skilled and has a lot of

knowledge in a specific areaEvaluator ndash a person who has good strategic skills keeps the balance

between immediate needs and long-term goals and weighs consequences

Five Characteristics of TeamworkThere are five characteristics that are the keys to a winning team The following characteristics are arranged in order of importance from highest to lowest1 Shared ValuesTeam members establish shared values and common goals and make the commitment to succeed2 Mutual TrustTeam members trust each other to get the job done They understand their role on the team is important and to put forth maximum effort to fulfill their promisesEveryone should express their opinions feelings and doubts Share information with your team This will help everyone to understand the project in greater detailTeam members should be enthusiastic with each other This will help produce the best performance as a team3 Inspiring VisionProvides direction and motivates the teamTeam members understand what needs to be done and how it can be doneThe focus should be on exceeding customer satisfaction The team should be inspired to work hard so that the products performance quality and cost are all rated excellent4 Skill TalentA team is stronger when team members are skilled in their discipline In addition when people are from different backgrounds they can work as a team to solve complex problemsA skilled individual is important however it is not as important as an individual who is a better team member A good team member prioritizes the values of the team trust on the team and the vision of the team5 Rewards Team members should be rewarded for their hard work and determination Rewards include going

out to eat a bonus or a promotionAs a manager it is your job to give positive reinforcement to your team members People feel good when

people show their appreciation for their contributions

Human Factors

As is well known Engineering Design is concerned with the satisfaction of human needs With this in mind it is quite obvious that there are many areas in which human factors must be taken into account in the design analysis The basic consideration in determining whether or not human factors are important is the possibility of a direct man-machine relationship Having determined the possibility and extent of involvement it is then necessary to consider the form of this relationship be it Anthropometric Ergonomic

Engineering Design is concerned with the satisfaction of human needs

In many applications human

factors must be taken into account in the design process

Man-machine interface )MMI( is very important to be considered in the design process

Human Factors in Engineering Design

Human factors in man-machine relationship have the following formsbull Anthropometric

)Human interaction in static sense dimensions of body)

bull Ergonomic)Human interaction in dynamic sense repeated tasks)

bull Physiological)Human interaction with body characteristics)

bull Psychological)Human interaction with mental activities)

37Human Factors

Man-Machine Interface

38Human Factors

Man-Machine Interface

The Design Engineer can determine the relative importance of human factors in his design

Anthropometric human factors are related to the physical size of humans it is man-machine interaction in static sense

One of the most common problems is that of driver accommodation in automobiles

Some may have experienced difficulties in either getting in or out reaching the controls or adequate visibility

These may have been due to inadequate attention to the nature of the physical dimensions of humans

40Human Factors

Anthropometric Factors

Human Factors41

Ergonomic Factors

Importance when the human operator is involved with the machine in a dynamic sense

A human is required to exert a force or perhaps supply work to the machine

It should be obvious that the effective operation of a machine over long periods of time will depend upon the matching of requirements to human capability

42Human Factors

Ergonomic Factors

Human Factors43

Ergonomic Factors

One simple example is that when the brake operating force is higher than can be normally tolerated The driver will cope with the situation at first but if the brake operation is frequent muscle fatigue will eventually occur and a dangerous situation will develop

The capability for performing mechanical tasks of this type depends upon

The physical ability of the operator The range of movement required The speed of movement The duration of the activity The position of the operator The environmental condition

44Human Factors

Ergonomic Factors

Human Factors45

Physiological Factors

Physiological factors are of concern when the physicochemical characteristics of the body are significant

As far as body functions are concerned these involve the neurological muscular respiratory vascular and sensory systems

The exterior manifestations can be grouped according to the response to various inputs such as

Visual Auditory Tactile kinesthetic and taste senses Environment

Color discrimination is impaired when illumination levels are low and this can lead to unexpected difficulties in comprehension

An associated problem of illumination which has a critical effect on contrast is that of glare and shadow formation These can be controlled by careful design of lighting systems and selection of materials and colors

46Human Factors

Physiological Factors

An excessive level of noise pollution is in fact undesirable for a number of reasons

Leads to degradation of speech intelligibility Will lead to physical damage to the human auditory system Hinders mental activity due to distracting influences Can lead to psychological and mental disorders if sustained

47Human Factors

Physiological Factors

The speech interference level )SIL( is a measure of the destructiveness of noise It is determined by the level of noise in certain frequency bands

High levels of sound intensity cause pain and even physical damage

The usually accepted threshold of pain is at about 05 Wm2

48Human Factors

Physiological Factors

Human Factors49

Psychological Factors

Psychological considerations in human factors analysis are concerned with the mental activity relationship between man and the machine This involves

bull Interpretation of informationbull Motivation and fatiguebull Decision makingbull Aesthetics

Human Factors50

Psychological Factors

These factors are concerned with the manner of presentation to minimize the error of interpretation

The design of visual displays such as control panels instrument panels and other informative displays is a typical example of psychological factors at work

There are a number of principles which have been developed Some of these include 1 Retain the usual method of operation )eg a power switch is ON when the operating lever is DOWN

2 Use digital indicators for precise numerical values with no need for interpretation That is satisfactory only when values are constant or not changing rapidly

3 For time variable readings not requiring high accuracy use moving pointers over a fixed linear or circular scale

51Human Factors

Psychological Factors

Human Factors52

Psychological Factors

4 Arrange control movement to coincide with required direction of instrument pointer movement

5 Color coding on dials are useful in helping to recognize conditions quickly eg green-normal yellow-caution red-danger

The mechanism of the control device should be designed so that )i( Movements are easy )ii( Slackness is eliminated )iii( The operator is aware of a feedback response )iv( The system response is rapid

If this cannot be achieved the controller should incorporate some restriction so that over reaction and instability does not develop

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

Team RolesThere are nine team roles defined to help the team function more effectively

Organizer ndash a person who visualizes and plans for the whole design process

Motivator ndash a person who takes care of the schedule and goals of the teamPusher ndash an active person who makes team work fasterSolver ndash an imaginative person who deals mainly with problem resolutionGatherer ndash a person who is good at collecting information and

communicating with other teamsListener ndash a perceptive person who can listen and combine the ideas and

statements of othersCompleter ndash a careful person who specializes in eliminating design defectsSpecialist ndash a dedicated person who is extremely skilled and has a lot of

knowledge in a specific areaEvaluator ndash a person who has good strategic skills keeps the balance

between immediate needs and long-term goals and weighs consequences

Five Characteristics of TeamworkThere are five characteristics that are the keys to a winning team The following characteristics are arranged in order of importance from highest to lowest1 Shared ValuesTeam members establish shared values and common goals and make the commitment to succeed2 Mutual TrustTeam members trust each other to get the job done They understand their role on the team is important and to put forth maximum effort to fulfill their promisesEveryone should express their opinions feelings and doubts Share information with your team This will help everyone to understand the project in greater detailTeam members should be enthusiastic with each other This will help produce the best performance as a team3 Inspiring VisionProvides direction and motivates the teamTeam members understand what needs to be done and how it can be doneThe focus should be on exceeding customer satisfaction The team should be inspired to work hard so that the products performance quality and cost are all rated excellent4 Skill TalentA team is stronger when team members are skilled in their discipline In addition when people are from different backgrounds they can work as a team to solve complex problemsA skilled individual is important however it is not as important as an individual who is a better team member A good team member prioritizes the values of the team trust on the team and the vision of the team5 Rewards Team members should be rewarded for their hard work and determination Rewards include going

out to eat a bonus or a promotionAs a manager it is your job to give positive reinforcement to your team members People feel good when

people show their appreciation for their contributions

Human Factors

As is well known Engineering Design is concerned with the satisfaction of human needs With this in mind it is quite obvious that there are many areas in which human factors must be taken into account in the design analysis The basic consideration in determining whether or not human factors are important is the possibility of a direct man-machine relationship Having determined the possibility and extent of involvement it is then necessary to consider the form of this relationship be it Anthropometric Ergonomic

Physiological Psychological

Engineering Design is concerned with the satisfaction of human needs

In many applications human

factors must be taken into account in the design process

Man-machine interface )MMI( is very important to be considered in the design process

Human Factors in Engineering Design

Human factors in man-machine relationship have the following formsbull Anthropometric

)Human interaction in static sense dimensions of body)

bull Ergonomic)Human interaction in dynamic sense repeated tasks)

bull Physiological)Human interaction with body characteristics)

bull Psychological)Human interaction with mental activities)

37Human Factors

Man-Machine Interface

38Human Factors

Man-Machine Interface

The Design Engineer can determine the relative importance of human factors in his design

Anthropometric human factors are related to the physical size of humans it is man-machine interaction in static sense

One of the most common problems is that of driver accommodation in automobiles

Some may have experienced difficulties in either getting in or out reaching the controls or adequate visibility

These may have been due to inadequate attention to the nature of the physical dimensions of humans

40Human Factors

Anthropometric Factors

Human Factors41

Ergonomic Factors

Importance when the human operator is involved with the machine in a dynamic sense

A human is required to exert a force or perhaps supply work to the machine

It should be obvious that the effective operation of a machine over long periods of time will depend upon the matching of requirements to human capability

42Human Factors

Ergonomic Factors

Human Factors43

Ergonomic Factors

One simple example is that when the brake operating force is higher than can be normally tolerated The driver will cope with the situation at first but if the brake operation is frequent muscle fatigue will eventually occur and a dangerous situation will develop

The capability for performing mechanical tasks of this type depends upon

The physical ability of the operator The range of movement required The speed of movement The duration of the activity The position of the operator The environmental condition

44Human Factors

Ergonomic Factors

Human Factors45

Physiological Factors

Physiological factors are of concern when the physicochemical characteristics of the body are significant

As far as body functions are concerned these involve the neurological muscular respiratory vascular and sensory systems

The exterior manifestations can be grouped according to the response to various inputs such as

Visual Auditory Tactile kinesthetic and taste senses Environment

Color discrimination is impaired when illumination levels are low and this can lead to unexpected difficulties in comprehension

An associated problem of illumination which has a critical effect on contrast is that of glare and shadow formation These can be controlled by careful design of lighting systems and selection of materials and colors

46Human Factors

Physiological Factors

An excessive level of noise pollution is in fact undesirable for a number of reasons

Leads to degradation of speech intelligibility Will lead to physical damage to the human auditory system Hinders mental activity due to distracting influences Can lead to psychological and mental disorders if sustained

47Human Factors

Physiological Factors

The speech interference level )SIL( is a measure of the destructiveness of noise It is determined by the level of noise in certain frequency bands

High levels of sound intensity cause pain and even physical damage

The usually accepted threshold of pain is at about 05 Wm2

48Human Factors

Physiological Factors

Human Factors49

Psychological Factors

Psychological considerations in human factors analysis are concerned with the mental activity relationship between man and the machine This involves

bull Interpretation of informationbull Motivation and fatiguebull Decision makingbull Aesthetics

Human Factors50

Psychological Factors

These factors are concerned with the manner of presentation to minimize the error of interpretation

The design of visual displays such as control panels instrument panels and other informative displays is a typical example of psychological factors at work

There are a number of principles which have been developed Some of these include 1 Retain the usual method of operation )eg a power switch is ON when the operating lever is DOWN

2 Use digital indicators for precise numerical values with no need for interpretation That is satisfactory only when values are constant or not changing rapidly

3 For time variable readings not requiring high accuracy use moving pointers over a fixed linear or circular scale

51Human Factors

Psychological Factors

Human Factors52

Psychological Factors

4 Arrange control movement to coincide with required direction of instrument pointer movement

5 Color coding on dials are useful in helping to recognize conditions quickly eg green-normal yellow-caution red-danger

The mechanism of the control device should be designed so that )i( Movements are easy )ii( Slackness is eliminated )iii( The operator is aware of a feedback response )iv( The system response is rapid

If this cannot be achieved the controller should incorporate some restriction so that over reaction and instability does not develop

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

Five Characteristics of TeamworkThere are five characteristics that are the keys to a winning team The following characteristics are arranged in order of importance from highest to lowest1 Shared ValuesTeam members establish shared values and common goals and make the commitment to succeed2 Mutual TrustTeam members trust each other to get the job done They understand their role on the team is important and to put forth maximum effort to fulfill their promisesEveryone should express their opinions feelings and doubts Share information with your team This will help everyone to understand the project in greater detailTeam members should be enthusiastic with each other This will help produce the best performance as a team3 Inspiring VisionProvides direction and motivates the teamTeam members understand what needs to be done and how it can be doneThe focus should be on exceeding customer satisfaction The team should be inspired to work hard so that the products performance quality and cost are all rated excellent4 Skill TalentA team is stronger when team members are skilled in their discipline In addition when people are from different backgrounds they can work as a team to solve complex problemsA skilled individual is important however it is not as important as an individual who is a better team member A good team member prioritizes the values of the team trust on the team and the vision of the team5 Rewards Team members should be rewarded for their hard work and determination Rewards include going

out to eat a bonus or a promotionAs a manager it is your job to give positive reinforcement to your team members People feel good when

people show their appreciation for their contributions

Human Factors

As is well known Engineering Design is concerned with the satisfaction of human needs With this in mind it is quite obvious that there are many areas in which human factors must be taken into account in the design analysis The basic consideration in determining whether or not human factors are important is the possibility of a direct man-machine relationship Having determined the possibility and extent of involvement it is then necessary to consider the form of this relationship be it Anthropometric Ergonomic

Engineering Design is concerned with the satisfaction of human needs

In many applications human

factors must be taken into account in the design process

Man-machine interface )MMI( is very important to be considered in the design process

Human Factors in Engineering Design

Human factors in man-machine relationship have the following formsbull Anthropometric

)Human interaction in static sense dimensions of body)

bull Ergonomic)Human interaction in dynamic sense repeated tasks)

bull Physiological)Human interaction with body characteristics)

bull Psychological)Human interaction with mental activities)

37Human Factors

Man-Machine Interface

38Human Factors

Man-Machine Interface

The Design Engineer can determine the relative importance of human factors in his design

Anthropometric human factors are related to the physical size of humans it is man-machine interaction in static sense

One of the most common problems is that of driver accommodation in automobiles

Some may have experienced difficulties in either getting in or out reaching the controls or adequate visibility

These may have been due to inadequate attention to the nature of the physical dimensions of humans

40Human Factors

Anthropometric Factors

Human Factors41

Ergonomic Factors

Importance when the human operator is involved with the machine in a dynamic sense

A human is required to exert a force or perhaps supply work to the machine

It should be obvious that the effective operation of a machine over long periods of time will depend upon the matching of requirements to human capability

42Human Factors

Ergonomic Factors

Human Factors43

Ergonomic Factors

One simple example is that when the brake operating force is higher than can be normally tolerated The driver will cope with the situation at first but if the brake operation is frequent muscle fatigue will eventually occur and a dangerous situation will develop

The capability for performing mechanical tasks of this type depends upon

The physical ability of the operator The range of movement required The speed of movement The duration of the activity The position of the operator The environmental condition

44Human Factors

Ergonomic Factors

Human Factors45

Physiological Factors

Physiological factors are of concern when the physicochemical characteristics of the body are significant

As far as body functions are concerned these involve the neurological muscular respiratory vascular and sensory systems

The exterior manifestations can be grouped according to the response to various inputs such as

Visual Auditory Tactile kinesthetic and taste senses Environment

Color discrimination is impaired when illumination levels are low and this can lead to unexpected difficulties in comprehension

An associated problem of illumination which has a critical effect on contrast is that of glare and shadow formation These can be controlled by careful design of lighting systems and selection of materials and colors

46Human Factors

Physiological Factors

An excessive level of noise pollution is in fact undesirable for a number of reasons

Leads to degradation of speech intelligibility Will lead to physical damage to the human auditory system Hinders mental activity due to distracting influences Can lead to psychological and mental disorders if sustained

47Human Factors

Physiological Factors

The speech interference level )SIL( is a measure of the destructiveness of noise It is determined by the level of noise in certain frequency bands

High levels of sound intensity cause pain and even physical damage

The usually accepted threshold of pain is at about 05 Wm2

48Human Factors

Physiological Factors

Human Factors49

Psychological Factors

Psychological considerations in human factors analysis are concerned with the mental activity relationship between man and the machine This involves

bull Interpretation of informationbull Motivation and fatiguebull Decision makingbull Aesthetics

Human Factors50

Psychological Factors

These factors are concerned with the manner of presentation to minimize the error of interpretation

The design of visual displays such as control panels instrument panels and other informative displays is a typical example of psychological factors at work

There are a number of principles which have been developed Some of these include 1 Retain the usual method of operation )eg a power switch is ON when the operating lever is DOWN

2 Use digital indicators for precise numerical values with no need for interpretation That is satisfactory only when values are constant or not changing rapidly

3 For time variable readings not requiring high accuracy use moving pointers over a fixed linear or circular scale

51Human Factors

Psychological Factors

Human Factors52

Psychological Factors

4 Arrange control movement to coincide with required direction of instrument pointer movement

5 Color coding on dials are useful in helping to recognize conditions quickly eg green-normal yellow-caution red-danger

The mechanism of the control device should be designed so that )i( Movements are easy )ii( Slackness is eliminated )iii( The operator is aware of a feedback response )iv( The system response is rapid

If this cannot be achieved the controller should incorporate some restriction so that over reaction and instability does not develop

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

The Design Engineer can determine the relative importance of human factors in his design

Anthropometric human factors are related to the physical size of humans it is man-machine interaction in static sense

One of the most common problems is that of driver accommodation in automobiles

Some may have experienced difficulties in either getting in or out reaching the controls or adequate visibility

These may have been due to inadequate attention to the nature of the physical dimensions of humans

Human Factors41

Ergonomic Factors

Importance when the human operator is involved with the machine in a dynamic sense

A human is required to exert a force or perhaps supply work to the machine

It should be obvious that the effective operation of a machine over long periods of time will depend upon the matching of requirements to human capability

Ergonomic Factors

One simple example is that when the brake operating force is higher than can be normally tolerated The driver will cope with the situation at first but if the brake operation is frequent muscle fatigue will eventually occur and a dangerous situation will develop

The capability for performing mechanical tasks of this type depends upon

The physical ability of the operator The range of movement required The speed of movement The duration of the activity The position of the operator The environmental condition

Physiological Factors

Physiological factors are of concern when the physicochemical characteristics of the body are significant

As far as body functions are concerned these involve the neurological muscular respiratory vascular and sensory systems

The exterior manifestations can be grouped according to the response to various inputs such as

Visual Auditory Tactile kinesthetic and taste senses Environment

Color discrimination is impaired when illumination levels are low and this can lead to unexpected difficulties in comprehension

An associated problem of illumination which has a critical effect on contrast is that of glare and shadow formation These can be controlled by careful design of lighting systems and selection of materials and colors

46Human Factors

Physiological Factors

An excessive level of noise pollution is in fact undesirable for a number of reasons

Leads to degradation of speech intelligibility Will lead to physical damage to the human auditory system Hinders mental activity due to distracting influences Can lead to psychological and mental disorders if sustained

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

Human Factors36

Engineering Design is concerned with the satisfaction of human needs

In many applications human

factors must be taken into account in the design process

Man-machine interface )MMI( is very important to be considered in the design process

Human Factors in Engineering Design

Human factors in man-machine relationship have the following formsbull Anthropometric

)Human interaction in static sense dimensions of body)

bull Ergonomic)Human interaction in dynamic sense repeated tasks)

bull Physiological)Human interaction with body characteristics)

bull Psychological)Human interaction with mental activities)

37Human Factors

Man-Machine Interface

38Human Factors

Man-Machine Interface

The Design Engineer can determine the relative importance of human factors in his design

Anthropometric human factors are related to the physical size of humans it is man-machine interaction in static sense

One of the most common problems is that of driver accommodation in automobiles

Some may have experienced difficulties in either getting in or out reaching the controls or adequate visibility

These may have been due to inadequate attention to the nature of the physical dimensions of humans

40Human Factors

Anthropometric Factors

Human Factors41

Ergonomic Factors

Importance when the human operator is involved with the machine in a dynamic sense

A human is required to exert a force or perhaps supply work to the machine

It should be obvious that the effective operation of a machine over long periods of time will depend upon the matching of requirements to human capability

42Human Factors

Ergonomic Factors

Human Factors43

Ergonomic Factors

One simple example is that when the brake operating force is higher than can be normally tolerated The driver will cope with the situation at first but if the brake operation is frequent muscle fatigue will eventually occur and a dangerous situation will develop

The capability for performing mechanical tasks of this type depends upon

The physical ability of the operator The range of movement required The speed of movement The duration of the activity The position of the operator The environmental condition

44Human Factors

Ergonomic Factors

Human Factors45

Physiological Factors

Physiological factors are of concern when the physicochemical characteristics of the body are significant

As far as body functions are concerned these involve the neurological muscular respiratory vascular and sensory systems

The exterior manifestations can be grouped according to the response to various inputs such as

Visual Auditory Tactile kinesthetic and taste senses Environment

Color discrimination is impaired when illumination levels are low and this can lead to unexpected difficulties in comprehension

An associated problem of illumination which has a critical effect on contrast is that of glare and shadow formation These can be controlled by careful design of lighting systems and selection of materials and colors

46Human Factors

Physiological Factors

An excessive level of noise pollution is in fact undesirable for a number of reasons

Leads to degradation of speech intelligibility Will lead to physical damage to the human auditory system Hinders mental activity due to distracting influences Can lead to psychological and mental disorders if sustained

47Human Factors

Physiological Factors

The speech interference level )SIL( is a measure of the destructiveness of noise It is determined by the level of noise in certain frequency bands

High levels of sound intensity cause pain and even physical damage

The usually accepted threshold of pain is at about 05 Wm2

48Human Factors

Physiological Factors

Human Factors49

Psychological Factors

Psychological considerations in human factors analysis are concerned with the mental activity relationship between man and the machine This involves

bull Interpretation of informationbull Motivation and fatiguebull Decision makingbull Aesthetics

Human Factors50

Psychological Factors

These factors are concerned with the manner of presentation to minimize the error of interpretation

The design of visual displays such as control panels instrument panels and other informative displays is a typical example of psychological factors at work

There are a number of principles which have been developed Some of these include 1 Retain the usual method of operation )eg a power switch is ON when the operating lever is DOWN

2 Use digital indicators for precise numerical values with no need for interpretation That is satisfactory only when values are constant or not changing rapidly

3 For time variable readings not requiring high accuracy use moving pointers over a fixed linear or circular scale

51Human Factors

Psychological Factors

Human Factors52

Psychological Factors

4 Arrange control movement to coincide with required direction of instrument pointer movement

5 Color coding on dials are useful in helping to recognize conditions quickly eg green-normal yellow-caution red-danger

The mechanism of the control device should be designed so that )i( Movements are easy )ii( Slackness is eliminated )iii( The operator is aware of a feedback response )iv( The system response is rapid

If this cannot be achieved the controller should incorporate some restriction so that over reaction and instability does not develop

Psychological Factors

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

Man-Machine Interface

The Design Engineer can determine the relative importance of human factors in his design

Anthropometric human factors are related to the physical size of humans it is man-machine interaction in static sense

One of the most common problems is that of driver accommodation in automobiles

Some may have experienced difficulties in either getting in or out reaching the controls or adequate visibility

These may have been due to inadequate attention to the nature of the physical dimensions of humans

40Human Factors

Human Factors43

Ergonomic Factors

One simple example is that when the brake operating force is higher than can be normally tolerated The driver will cope with the situation at first but if the brake operation is frequent muscle fatigue will eventually occur and a dangerous situation will develop

The capability for performing mechanical tasks of this type depends upon

The physical ability of the operator The range of movement required The speed of movement The duration of the activity The position of the operator The environmental condition

44Human Factors

Ergonomic Factors

Human Factors45

Physiological Factors

Physiological factors are of concern when the physicochemical characteristics of the body are significant

As far as body functions are concerned these involve the neurological muscular respiratory vascular and sensory systems

The exterior manifestations can be grouped according to the response to various inputs such as

Visual Auditory Tactile kinesthetic and taste senses Environment

Color discrimination is impaired when illumination levels are low and this can lead to unexpected difficulties in comprehension

An associated problem of illumination which has a critical effect on contrast is that of glare and shadow formation These can be controlled by careful design of lighting systems and selection of materials and colors

46Human Factors

Physiological Factors

An excessive level of noise pollution is in fact undesirable for a number of reasons

Leads to degradation of speech intelligibility Will lead to physical damage to the human auditory system Hinders mental activity due to distracting influences Can lead to psychological and mental disorders if sustained

47Human Factors

Physiological Factors

The speech interference level )SIL( is a measure of the destructiveness of noise It is determined by the level of noise in certain frequency bands

High levels of sound intensity cause pain and even physical damage

The usually accepted threshold of pain is at about 05 Wm2

Psychological Factors

Psychological considerations in human factors analysis are concerned with the mental activity relationship between man and the machine This involves

bull Interpretation of informationbull Motivation and fatiguebull Decision makingbull Aesthetics

Human Factors50

Psychological Factors

These factors are concerned with the manner of presentation to minimize the error of interpretation

The design of visual displays such as control panels instrument panels and other informative displays is a typical example of psychological factors at work

There are a number of principles which have been developed Some of these include 1 Retain the usual method of operation )eg a power switch is ON when the operating lever is DOWN

2 Use digital indicators for precise numerical values with no need for interpretation That is satisfactory only when values are constant or not changing rapidly

3 For time variable readings not requiring high accuracy use moving pointers over a fixed linear or circular scale

4 Arrange control movement to coincide with required direction of instrument pointer movement

5 Color coding on dials are useful in helping to recognize conditions quickly eg green-normal yellow-caution red-danger

The mechanism of the control device should be designed so that )i( Movements are easy )ii( Slackness is eliminated )iii( The operator is aware of a feedback response )iv( The system response is rapid

If this cannot be achieved the controller should incorporate some restriction so that over reaction and instability does not develop

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

Anthropometric human factors are related to the physical size of humans it is man-machine interaction in static sense

One of the most common problems is that of driver accommodation in automobiles

Some may have experienced difficulties in either getting in or out reaching the controls or adequate visibility

These may have been due to inadequate attention to the nature of the physical dimensions of humans

40Human Factors

Anthropometric Factors

Human Factors41

Ergonomic Factors

Importance when the human operator is involved with the machine in a dynamic sense

A human is required to exert a force or perhaps supply work to the machine

It should be obvious that the effective operation of a machine over long periods of time will depend upon the matching of requirements to human capability

42Human Factors

Ergonomic Factors

Human Factors43

Ergonomic Factors

One simple example is that when the brake operating force is higher than can be normally tolerated The driver will cope with the situation at first but if the brake operation is frequent muscle fatigue will eventually occur and a dangerous situation will develop

The capability for performing mechanical tasks of this type depends upon

The physical ability of the operator The range of movement required The speed of movement The duration of the activity The position of the operator The environmental condition

44Human Factors

Ergonomic Factors

Human Factors45

Physiological Factors

Physiological factors are of concern when the physicochemical characteristics of the body are significant

As far as body functions are concerned these involve the neurological muscular respiratory vascular and sensory systems

The exterior manifestations can be grouped according to the response to various inputs such as

Visual Auditory Tactile kinesthetic and taste senses Environment

Color discrimination is impaired when illumination levels are low and this can lead to unexpected difficulties in comprehension

An associated problem of illumination which has a critical effect on contrast is that of glare and shadow formation These can be controlled by careful design of lighting systems and selection of materials and colors

46Human Factors

Physiological Factors

An excessive level of noise pollution is in fact undesirable for a number of reasons

Leads to degradation of speech intelligibility Will lead to physical damage to the human auditory system Hinders mental activity due to distracting influences Can lead to psychological and mental disorders if sustained

47Human Factors

Physiological Factors

The speech interference level )SIL( is a measure of the destructiveness of noise It is determined by the level of noise in certain frequency bands

High levels of sound intensity cause pain and even physical damage

The usually accepted threshold of pain is at about 05 Wm2

48Human Factors

Physiological Factors

Human Factors49

Psychological Factors

Psychological considerations in human factors analysis are concerned with the mental activity relationship between man and the machine This involves

bull Interpretation of informationbull Motivation and fatiguebull Decision makingbull Aesthetics

Human Factors50

Psychological Factors

These factors are concerned with the manner of presentation to minimize the error of interpretation

The design of visual displays such as control panels instrument panels and other informative displays is a typical example of psychological factors at work

There are a number of principles which have been developed Some of these include 1 Retain the usual method of operation )eg a power switch is ON when the operating lever is DOWN

2 Use digital indicators for precise numerical values with no need for interpretation That is satisfactory only when values are constant or not changing rapidly

3 For time variable readings not requiring high accuracy use moving pointers over a fixed linear or circular scale

51Human Factors

Psychological Factors

Human Factors52

Psychological Factors

4 Arrange control movement to coincide with required direction of instrument pointer movement

5 Color coding on dials are useful in helping to recognize conditions quickly eg green-normal yellow-caution red-danger

The mechanism of the control device should be designed so that )i( Movements are easy )ii( Slackness is eliminated )iii( The operator is aware of a feedback response )iv( The system response is rapid

If this cannot be achieved the controller should incorporate some restriction so that over reaction and instability does not develop

One of the most common problems is that of driver accommodation in automobiles

Some may have experienced difficulties in either getting in or out reaching the controls or adequate visibility

These may have been due to inadequate attention to the nature of the physical dimensions of humans

40Human Factors

Anthropometric Factors

Human Factors41

Ergonomic Factors

Importance when the human operator is involved with the machine in a dynamic sense

A human is required to exert a force or perhaps supply work to the machine

It should be obvious that the effective operation of a machine over long periods of time will depend upon the matching of requirements to human capability

42Human Factors

Ergonomic Factors

Human Factors43

Ergonomic Factors

One simple example is that when the brake operating force is higher than can be normally tolerated The driver will cope with the situation at first but if the brake operation is frequent muscle fatigue will eventually occur and a dangerous situation will develop

The capability for performing mechanical tasks of this type depends upon

The physical ability of the operator The range of movement required The speed of movement The duration of the activity The position of the operator The environmental condition

44Human Factors

Ergonomic Factors

Human Factors45

Physiological Factors

Physiological factors are of concern when the physicochemical characteristics of the body are significant

As far as body functions are concerned these involve the neurological muscular respiratory vascular and sensory systems

The exterior manifestations can be grouped according to the response to various inputs such as

Visual Auditory Tactile kinesthetic and taste senses Environment

Color discrimination is impaired when illumination levels are low and this can lead to unexpected difficulties in comprehension

An associated problem of illumination which has a critical effect on contrast is that of glare and shadow formation These can be controlled by careful design of lighting systems and selection of materials and colors

46Human Factors

Physiological Factors

An excessive level of noise pollution is in fact undesirable for a number of reasons

Leads to degradation of speech intelligibility Will lead to physical damage to the human auditory system Hinders mental activity due to distracting influences Can lead to psychological and mental disorders if sustained

47Human Factors

Physiological Factors

The speech interference level )SIL( is a measure of the destructiveness of noise It is determined by the level of noise in certain frequency bands

High levels of sound intensity cause pain and even physical damage

The usually accepted threshold of pain is at about 05 Wm2

48Human Factors

Physiological Factors

Human Factors49

Psychological Factors

Psychological considerations in human factors analysis are concerned with the mental activity relationship between man and the machine This involves

bull Interpretation of informationbull Motivation and fatiguebull Decision makingbull Aesthetics

Human Factors50

Psychological Factors

These factors are concerned with the manner of presentation to minimize the error of interpretation

The design of visual displays such as control panels instrument panels and other informative displays is a typical example of psychological factors at work

There are a number of principles which have been developed Some of these include 1 Retain the usual method of operation )eg a power switch is ON when the operating lever is DOWN

2 Use digital indicators for precise numerical values with no need for interpretation That is satisfactory only when values are constant or not changing rapidly

3 For time variable readings not requiring high accuracy use moving pointers over a fixed linear or circular scale

51Human Factors

Psychological Factors

Human Factors52

Psychological Factors

4 Arrange control movement to coincide with required direction of instrument pointer movement

5 Color coding on dials are useful in helping to recognize conditions quickly eg green-normal yellow-caution red-danger

The mechanism of the control device should be designed so that )i( Movements are easy )ii( Slackness is eliminated )iii( The operator is aware of a feedback response )iv( The system response is rapid

If this cannot be achieved the controller should incorporate some restriction so that over reaction and instability does not develop

Psychological Factors

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

These factors are concerned with the manner of presentation to minimize the error of interpretation

The design of visual displays such as control panels instrument panels and other informative displays is a typical example of psychological factors at work

There are a number of principles which have been developed Some of these include 1 Retain the usual method of operation )eg a power switch is ON when the operating lever is DOWN

2 Use digital indicators for precise numerical values with no need for interpretation That is satisfactory only when values are constant or not changing rapidly

3 For time variable readings not requiring high accuracy use moving pointers over a fixed linear or circular scale

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

Importance when the human operator is involved with the machine in a dynamic sense

A human is required to exert a force or perhaps supply work to the machine

It should be obvious that the effective operation of a machine over long periods of time will depend upon the matching of requirements to human capability

Ergonomic Factors

Human Factors43

Ergonomic Factors

One simple example is that when the brake operating force is higher than can be normally tolerated The driver will cope with the situation at first but if the brake operation is frequent muscle fatigue will eventually occur and a dangerous situation will develop

The capability for performing mechanical tasks of this type depends upon

The physical ability of the operator The range of movement required The speed of movement The duration of the activity The position of the operator The environmental condition

Physiological Factors

Physiological factors are of concern when the physicochemical characteristics of the body are significant

As far as body functions are concerned these involve the neurological muscular respiratory vascular and sensory systems

The exterior manifestations can be grouped according to the response to various inputs such as

Visual Auditory Tactile kinesthetic and taste senses Environment

Color discrimination is impaired when illumination levels are low and this can lead to unexpected difficulties in comprehension

An associated problem of illumination which has a critical effect on contrast is that of glare and shadow formation These can be controlled by careful design of lighting systems and selection of materials and colors

Human Factors43

Ergonomic Factors

One simple example is that when the brake operating force is higher than can be normally tolerated The driver will cope with the situation at first but if the brake operation is frequent muscle fatigue will eventually occur and a dangerous situation will develop

The capability for performing mechanical tasks of this type depends upon

The physical ability of the operator The range of movement required The speed of movement The duration of the activity The position of the operator The environmental condition

44Human Factors

Ergonomic Factors

Human Factors45

Physiological Factors

Physiological factors are of concern when the physicochemical characteristics of the body are significant

As far as body functions are concerned these involve the neurological muscular respiratory vascular and sensory systems

The exterior manifestations can be grouped according to the response to various inputs such as

Visual Auditory Tactile kinesthetic and taste senses Environment

Color discrimination is impaired when illumination levels are low and this can lead to unexpected difficulties in comprehension

An associated problem of illumination which has a critical effect on contrast is that of glare and shadow formation These can be controlled by careful design of lighting systems and selection of materials and colors

46Human Factors

Physiological Factors

An excessive level of noise pollution is in fact undesirable for a number of reasons

Leads to degradation of speech intelligibility Will lead to physical damage to the human auditory system Hinders mental activity due to distracting influences Can lead to psychological and mental disorders if sustained

47Human Factors

Physiological Factors

The speech interference level )SIL( is a measure of the destructiveness of noise It is determined by the level of noise in certain frequency bands

High levels of sound intensity cause pain and even physical damage

The usually accepted threshold of pain is at about 05 Wm2

48Human Factors

Physiological Factors

Human Factors49

Psychological Factors

Psychological considerations in human factors analysis are concerned with the mental activity relationship between man and the machine This involves

bull Interpretation of informationbull Motivation and fatiguebull Decision makingbull Aesthetics

Human Factors50

Psychological Factors

These factors are concerned with the manner of presentation to minimize the error of interpretation

The design of visual displays such as control panels instrument panels and other informative displays is a typical example of psychological factors at work

There are a number of principles which have been developed Some of these include 1 Retain the usual method of operation )eg a power switch is ON when the operating lever is DOWN

2 Use digital indicators for precise numerical values with no need for interpretation That is satisfactory only when values are constant or not changing rapidly

3 For time variable readings not requiring high accuracy use moving pointers over a fixed linear or circular scale

51Human Factors

Psychological Factors

Human Factors52

Psychological Factors

4 Arrange control movement to coincide with required direction of instrument pointer movement

5 Color coding on dials are useful in helping to recognize conditions quickly eg green-normal yellow-caution red-danger

The mechanism of the control device should be designed so that )i( Movements are easy )ii( Slackness is eliminated )iii( The operator is aware of a feedback response )iv( The system response is rapid

If this cannot be achieved the controller should incorporate some restriction so that over reaction and instability does not develop

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

Physiological Factors

The speech interference level )SIL( is a measure of the destructiveness of noise It is determined by the level of noise in certain frequency bands

High levels of sound intensity cause pain and even physical damage

The usually accepted threshold of pain is at about 05 Wm2

Psychological Factors

These factors are concerned with the manner of presentation to minimize the error of interpretation

The design of visual displays such as control panels instrument panels and other informative displays is a typical example of psychological factors at work

There are a number of principles which have been developed Some of these include 1 Retain the usual method of operation )eg a power switch is ON when the operating lever is DOWN

2 Use digital indicators for precise numerical values with no need for interpretation That is satisfactory only when values are constant or not changing rapidly

3 For time variable readings not requiring high accuracy use moving pointers over a fixed linear or circular scale

4 Arrange control movement to coincide with required direction of instrument pointer movement

5 Color coding on dials are useful in helping to recognize conditions quickly eg green-normal yellow-caution red-danger

The mechanism of the control device should be designed so that )i( Movements are easy )ii( Slackness is eliminated )iii( The operator is aware of a feedback response )iv( The system response is rapid

If this cannot be achieved the controller should incorporate some restriction so that over reaction and instability does not develop

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

Physiological Factors

Physiological factors are of concern when the physicochemical characteristics of the body are significant

As far as body functions are concerned these involve the neurological muscular respiratory vascular and sensory systems

The exterior manifestations can be grouped according to the response to various inputs such as

Visual Auditory Tactile kinesthetic and taste senses Environment

Color discrimination is impaired when illumination levels are low and this can lead to unexpected difficulties in comprehension

An associated problem of illumination which has a critical effect on contrast is that of glare and shadow formation These can be controlled by careful design of lighting systems and selection of materials and colors

Color discrimination is impaired when illumination levels are low and this can lead to unexpected difficulties in comprehension

An associated problem of illumination which has a critical effect on contrast is that of glare and shadow formation These can be controlled by careful design of lighting systems and selection of materials and colors

46Human Factors

Physiological Factors

An excessive level of noise pollution is in fact undesirable for a number of reasons

Leads to degradation of speech intelligibility Will lead to physical damage to the human auditory system Hinders mental activity due to distracting influences Can lead to psychological and mental disorders if sustained

47Human Factors

Physiological Factors

The speech interference level )SIL( is a measure of the destructiveness of noise It is determined by the level of noise in certain frequency bands

High levels of sound intensity cause pain and even physical damage

The usually accepted threshold of pain is at about 05 Wm2

Psychological Factors

Psychological considerations in human factors analysis are concerned with the mental activity relationship between man and the machine This involves

bull Interpretation of informationbull Motivation and fatiguebull Decision makingbull Aesthetics

Human Factors50

Psychological Factors

These factors are concerned with the manner of presentation to minimize the error of interpretation

The design of visual displays such as control panels instrument panels and other informative displays is a typical example of psychological factors at work

There are a number of principles which have been developed Some of these include 1 Retain the usual method of operation )eg a power switch is ON when the operating lever is DOWN

2 Use digital indicators for precise numerical values with no need for interpretation That is satisfactory only when values are constant or not changing rapidly

3 For time variable readings not requiring high accuracy use moving pointers over a fixed linear or circular scale

4 Arrange control movement to coincide with required direction of instrument pointer movement

5 Color coding on dials are useful in helping to recognize conditions quickly eg green-normal yellow-caution red-danger

The mechanism of the control device should be designed so that )i( Movements are easy )ii( Slackness is eliminated )iii( The operator is aware of a feedback response )iv( The system response is rapid

If this cannot be achieved the controller should incorporate some restriction so that over reaction and instability does not develop

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

Psychological Factors

These factors are concerned with the manner of presentation to minimize the error of interpretation

The design of visual displays such as control panels instrument panels and other informative displays is a typical example of psychological factors at work

There are a number of principles which have been developed Some of these include 1 Retain the usual method of operation )eg a power switch is ON when the operating lever is DOWN

2 Use digital indicators for precise numerical values with no need for interpretation That is satisfactory only when values are constant or not changing rapidly

3 For time variable readings not requiring high accuracy use moving pointers over a fixed linear or circular scale

4 Arrange control movement to coincide with required direction of instrument pointer movement

5 Color coding on dials are useful in helping to recognize conditions quickly eg green-normal yellow-caution red-danger

The mechanism of the control device should be designed so that )i( Movements are easy )ii( Slackness is eliminated )iii( The operator is aware of a feedback response )iv( The system response is rapid

If this cannot be achieved the controller should incorporate some restriction so that over reaction and instability does not develop

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

Psychological Factors

These factors are concerned with the manner of presentation to minimize the error of interpretation

The design of visual displays such as control panels instrument panels and other informative displays is a typical example of psychological factors at work

There are a number of principles which have been developed Some of these include 1 Retain the usual method of operation )eg a power switch is ON when the operating lever is DOWN

2 Use digital indicators for precise numerical values with no need for interpretation That is satisfactory only when values are constant or not changing rapidly

3 For time variable readings not requiring high accuracy use moving pointers over a fixed linear or circular scale

4 Arrange control movement to coincide with required direction of instrument pointer movement

5 Color coding on dials are useful in helping to recognize conditions quickly eg green-normal yellow-caution red-danger

The mechanism of the control device should be designed so that )i( Movements are easy )ii( Slackness is eliminated )iii( The operator is aware of a feedback response )iv( The system response is rapid

If this cannot be achieved the controller should incorporate some restriction so that over reaction and instability does not develop

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

Guidelines for Final Oral Presentation

Presentations of the projects are typically given in the last week of the semester to an audience of fellow student reviewers project sponsors design faculty and occasional faculty who are following up a project of personal interest to them

The oral presentation should follow a format that is similar to the written report Here is a general outline to follow

bullIntroductionbullObjectivebullReview original designbullDescribe project build and functional testsbullDiscuss successes and challengesbullOther testsbullRecommendations

It is important that your presentation fit into the time allowed You must rehearse your presentation to get the timing right A rule of thumb is that you have roughly one slide per minute of presentation time You convey information though both the visual and audio portions of the presentation These two parts of the presentation should complement each other the words should support the slides and vice-versa You should avoid having both portions the same words meaning that you should avoid simply reading the visual materials

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

Below are some guidelines for preparing your slidesbullHave all slides prepared ahead of timebull All fonts must be large enough to be easily seen from all points in the roombull Avoid using an excessive amount of text write brief phrases rather than paragraphsbull Write down all the important points do not rely on the audience hearing everything you saybull Use bullets with each phrasebull Use diagrams and figures as much as possible pictures are more interesting than wordsbull Make the visual materials as interesting as possible make effective use of font style and colorbull Conversely the presentation should be professional minimize the use of silly slide transitions animations or sound effectsbull Test any demonstrations not in-line with the PowerPoint presentation )eg playing(bullsound files movies or Matlab demos( test these in the presentation room before the final talk if possible

Some general guidelines for your verbal presentation

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

bull Be prepared Practice Practice Practicebull Speak slowly and clearlybull Face the audience try to look each part of the audience at some point during thepresentationbull Use note cards if necessary but only as a last resort A good set of slides shouldremind you of what to say in between the text on the slidebull Avoid fidgeting and excessive movement it distracts the audiencebull Use a laser pointer to make the audience look where you want them to

The important parts of the presentation include

1 Title slideThe title slide should contain the title of the presentation the names of the presenters their affiliations slide does not look crowded 2 OverviewThis slide shows the audience how your presentation is organized The parts of the report should be listed using bullets Avoid incredibly obvious bullets )and the accompanying words( eg ldquoFirst I will give an introduction to our presentation I will present the project and conclude with some thoughts on future work Everyone knows this is the general structure of any talk It makes things more interesting if you bullet the general technical parts of the talk after a brief slide giving the project statement

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk

3 Figure slidesFigures are an important part of your presentation There are many different types of figures and some must be handled differently than others Block diagrams should be as simple and clear as possible and all fonts must be large enough to be read from all parts of the room Avoid block diagrams that are too crowded In presenting a block diagram you should walk the audience through the diagram Graph figures must have clearly labeled axes and any important conditions for the data should be listed Again you must point out the significance of the graph to the audience Test your slides beforehand to see if the lines and colors in a graph can be seen and differentiated from the back of a room Often presenters make the mistake of exporting a result directly from PSpice Matlab etc only to find that the audience cant tell the difference between regular and dotted lines or lines with different symbols and colors 4 Text slidesSlides with only text andor equations should not be over-crowded Use short bulleted phrases rather than long sentences You can expand on the bullets in the verbal part of the presentation If you present equations avoid long derivations but instead present ldquoresult equations Use LaTeX or the Microsoft Equation Editor to make the equations easy to read

5 ConclusionsThe last slides should reiterate the important points that were made during the presentation You want these slides to contain the information that you want the audience to ldquotake away from your presentation and give some suggestions for how you would build on this work in the future 6 DemonstrationsA demonstration can greatly enhance a presentation by emphasizing important accomplishments andor allowing the audience to experience what you are talking about However the problem with presentations is that they sometimes do not work leading to an embarrassing time for the presenters If you do decide to make a demonstration try to make it as foolproof as possible and have set up ahead of time there should not be a delay to set up a demonstration Test the demonstration beforehand on the PC where you will give the talk
