Human Computer Interaction

Subject : engineering
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Low- fidelity prototypes - Evaluations - Wireframes - Functional prototypes

8. 1.run out of metaphors 2.mixed metaphors 3.carry connotations and association






9. Intention formation - specification of the action - and the execution stages are complex - Require a rather accurate mental model of the computer's internal processing






10. 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






11. Participants - design - tester






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






13. 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






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






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






16. Articulatory distance is large because we are presented with the command prompt - no indication of functionality






17. They increase productivity - They offer constraint and consistency checks - They facilitate team approaches - They ease maintenance






18. We respond first to the intensity of a stimulus and only then do we begin to process its meaning






19. They allow an easy way to explore the problem space - They provide a way to create clusters of related elements - They provide a graphical view of the problem space - They resonate with the ways in which people process information






20. Gulfs of execution relate to the effectiveness principle - Gulfs of evaluation relate to the efficiency principle

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






37. The range of possible intentions is consistently wide - users usually have multiple options for specifying action sequences - provide multiple ways of executing action sequence






38. 1. the people who are involved with the work 2. the things they use to do the work - 3. the process that are involved in the work - 4. the information required to do the work - 5. the constraints imposed on the work - 6. the inputs required by the wo






39. They are quick and easy to perform - They can be done before any preliminary designs have been made - They will let you know how people organize information - They will expose underlying structures






40. Comprehensibility and learnability






41. Graphical libraries - User interface toolkits - Visual interface builders - Web development tools






42. 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






43. Ease of Learning - Efficiency of use - Memorability - Error frequency and severity - Subjective satisfaction






44. Use multiple independent evaluators - Use observer to record evaluator - Go through interface several times - Compare interaction against list of heuristics - Use heuristics specific to design - List heuristic problems and how the heuristic is violat
