Illustrating Events and Steps

Product Design Sketching

Explaining Sequences and Operations

Product design deals with The form The use

The interactions between users and products The user notices changes in the product The user changes the form of the product

We use diagrams to help us to ‘play’ the interactions and to communicate our design intent

Simple Operations

Single-action operations Holding a product Pressing buttons Turning a knob

Including part of human body in a sketch can be very effective

Movement

Longer stroke, with specific target Inserting coins Pulling tabs Flipping a cover

Use arrows to indicate locus and target

Compound Actions

Show path with direction change

Draw the arrow according to the path

The orientation of component should match that of the arrow head to avoid confusion

Steps

A chain of events Usually combined

with an exploded drawing

Number arrows to indicate sequence

Position the components in a simple path

Integrated Sketches

Explain operation and construction at the same time

Position components according to how they open or swing

Use captions and different types of arrows to prevent confusion

Activity

Draw diagrams to illustrate the following events Putting coins into a public telephone Passing Octopus card over an MTR gate Inserting a bank-card into an ATM Pulling out a stylus from PDA

Must include at least a palm Draw on tracing paper, one diagram per A4

sheet Use suitable colour combination to enhance

visual clarity Tune for table-top presentation

Multi-Frame Diagrams

For complicate interactionMore than one componentChange in focusChange in product formFinal presentation

One Action per Frame

One simple action per frameNo change in product orientationEasy to relate

Compound Actions

Compound actions may be usedMust use the same orientation to avoid

confusion

View Angle Inconsistency

Viewer may interpret the two steps as two different objects in one step

Confusing View Angles

Avoid view angles that have few visual cues

Avoid view angles that are not related to normal product use

Misleading Arrows

Avoid arrows with more than one possible interpretation

View angle inconsistency leads to confusion

Instructions w/ hand

Instructions w/ arrow

Activity

Draw how to use the buttons of your camera (1 sketch)

Draw how to remove memory card from your camera (a series of sketches)

Use as few texts as possibleInclude human figures or hands in your

composition
