9. 1.not self- explanatory 2.inefficient use of screen real estate 3.high graphical system requirements

10. Functionality->presentation filter | (comprehensibility barrier)| efficiency usability ->|(learnability barrier) | Effectiveness Usefulness

11. 1.low command retention 2. steep learning curve 3.high error rates 4.heavy reliance on memory 5.frustrating for novice users

12. They can be difficult to create f the target audience is international - Having too many personas will make the work difficult - There is a risk of incorporating unsupported designer assumption

13. Participants - design - tester

14. They can be used early and often - They are inexpensive and easy to create - They make design idea visual - No special knowledge is required - all team members can create them

15. Determine the function of the device - Determine what actions are possible - Determine mapping from intention to physical movement - Perform the action - Determine whether the system is in the desired state - Determine the mapping from system state t

16. They only involve the elements that you have written on the cards - They suggest solutions that imply structure - They become difficult to navigate with more categories

17. Menu constraints can help the user to form the proper intentions and specify the proper action sequence - provide a context to evaluate the output language

18. Progressive Disclosure - Constraints

19. Easy and inexpensive to make - Flexible enough to be constantly changed and rearranged - Complete enough to yield useful feedback about specific design questions

20. 1. low memory requirements 2. self- explanatory 3.easy to undo errors 4. sppropriate for beginners

21. Minimize help desk calls - increase product loyalty - Provide benchmarks for future products

22. They are not interactive - They cannot be used to calculate response timings - They do not deal with interface issues such as color or font size

23. Comprehensibility and learnability

24. User interface independence 1.They separate interface design from internals 2.They enable multiple user interface strategies 3. They enable multiple platform support 4. They establish the role of the user interface architect 5. They enforce standards

25. Low- fidelity prototypes - Evaluations - Wireframes - Functional prototypes
