6. Direct manipulations (volume up/down)
7. Multi-touch and gesture (fitbit)
8. 3D Navigation
9. Conversational (Siri)
HCI attention principles (4) - ANSWER: - anticipate needs
- highlight changes
- limit interruptions and distractions
- minimize information access cost
HCI perception principle (1) - ANSWER: - make system structure and affordances
visible (indicate what actions are possible)
HCI memory principles (2) - ANSWER: - recognition over recall (GUI rather than
command line)
- be consistent (same info in same place on every screen)
HCI mental model principles (3) - ANSWER: - match system to real world
- make credible and trustable
- consider aesthetics and simplicity
HCI response selection principles (2) - ANSWER: - choose appropriate defaults
- simplify and structure task sequences (small simple steps)
HCI interaction principles (3) - ANSWER: - make system state visible
, - support flexibility, efficiency, and personalization
- make robust to errors and exploration
evaluation of HCI - ANSWER: - learnability
- efficiency
- memorability
- errors
- satisfaction
measuring mental workload - ANSWER: - primary task measures
- secondary task measures
- physiological measures (eye activity indices, heart rate indices, EEG, NIRS)
- subjective measures
impacting factors on usability of icons - ANSWER: - concreteness
- visual complexity
- semantic distance
- familiarity
concreteness - ANSWER: - extent to which icon depicts real life objects rather than
abstract depictions
- important when icon is unfamiliar
visual complexity - ANSWER: - more complex gives user more context
- however, slower to process more complex depictions
semantic distance - ANSWER: closeness between depiction and its meaning
product warnings - ANSWER: - signal word
- statement of nature of hazard
- instruction statement
- consequence statement
- "caution" "toxic" "use mask when operating" "could cause death if inhaled"
processing product warnings - ANSWER: - noticing
- reading
- understanding
- complying
guidelines for language and communication - ANSWER: - maximize bottom-up
processing
- maximize automaticity and unitization
- maximize top-down processing
- maximize discriminating features
maximize bottom-up processing - ANSWER: - increase visibility
- avoid similarity of message sets presented in same context
