CS415 Human Computer Interaction

Exam #2 Review (Chapters 10, 12 & 20, Notes)

Overall Take-Away Human – Focus on the Value to the User, their Time, Universal access and use, to improve quality of life, cognitive interaction Computer – Methods to create devices, design interaction as software protocols, and present information Interaction – Handle errors, provide positive clear feedback, with efficiency, free of fatigue, with methods of interaction available to all “Our inventions are wont to be pretty toys, which distract our attention from serious things. They are but improved means to an unimproved end…” – Henry David Thoreau, Walden

Chapter 10 – Universal Design Design for Diversity – Sensory, Physical or Cognitive Impairment – Age Groups – Varying Cultures and Backgrounds, Localization – Languages

7 Principles of Universal Design 1. Equitable Use – No User is Excluded 2. Flexibility – Methods of Use, Pace, Precision, Ability 3. Intuitive – Wide Range of Knowledge and Experience 4. Perceptible Information – Graphic, Verbal, Text, Touch 5. Error Tolerance – Minimize Impact of Mistakes (e.g. Undo) 6. Low Physical Effort – Comfortable, Minimal Fatigue 7. Size and Space – Sitting or Standing, Body Size, Posture,

Mobility

Chapter 12 – Cognitive Models 1. Hierarchical Models – Task and Goal Structure 2. Linguistic Models – System Grammar 3. Physical and Device Models – Human Motor Skills 4. Cognitive Models – Combine All 3 of the Above

GOMS = Goals, Operators, Methods, Selection Linguistic – Forms, Natural Language Processing (Chomsky Hierachy, Semantics [Lambda Calculus, Turing Machines, Goedel’s Completeness] Physical and Device – Latency, Thought Between Actions, Cursor Positioning, Fitt’s Law, etc. Combined Models – Game Engines (e.g. Chess), fMRI, Barnards ICS (Interactive Cognitive Systems) Sam Siewert 6

Chapter 20 – Ubiquitous Computing Defined by Mark Weiser (Xerox PARC) – Merge computational artifacts smoothly with world of physical artifacts

(applications integrated with things) – Superimpose relevant information over top of the object – Objects in the physical world to manipulate virtual (graspable) – Context aware applications (Who, What, Where, When, Why) –

Recommendation Engines, Adware, Personal Assistants – Vannevar Bush (Memex) – Often compared to Hypertext Today

VR – Immersive, Desktop Feeling of Presence in Simulated World AR – Projection onto World (See World Through Modified View), Integration of Computer Vision and Graphics IoT & IIoT – Internet of Things and Industrial IoT Sam Siewert 7
