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.

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






17. Physical - cultural - functional - informational






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






19. Participants - design - tester






20. Location - Logical Grouping - Conventions - Redundancy






21. They make it possible to try out ideas very early - They make it possible to test - revise - test - revise...They engage end users -- managers and customers






22. 1.require valid input supplied by user 2.require familiarity with interface control 3.can be tedious to correct mistakes






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






24. 1.easy to learn2.low memory requirements 3.easy to undo 4.immediate feedback to user actions 5.enable user to use spatial cues 6.easy for beginner

27. Structuring the information space - Creating of alternative solutions - Determining which design concept to purse






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






29. 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






30. 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


31. What it will look like - What components it will require - How the screens will be laid out

33. 1. suitable for repetitive tasks 2. sdvantageous for expert users 3.offer direct access to system functionality 4.efficient and powerful 5.not encumbered with graphic controls - low visual load - not taxing on system resource 6. scriptable






34. Menu options create small articulatory distance






35. Unscientific - Partial - Unstable - Inconsistent - Personal






36. 1.ease of learning - 2.low memory requirement - 3.flexible interaction - 4.low screen requirement - 5. sppropriate for beginner






37. 1.They facilitate the development of design procedures 2.They help in finding ways to talk about design 3.They create project management






38. 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






39. 1.rapid and inflexible navigation 2.inefficient for large menu navigation 3.inefficient use of screen real estate 4. slow for expert






40. They require knowledge of problem space - They can lead beyond the problem space - There is no formal semantics for defining symbol meaning






41. 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






42. 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






43. Artificial context - Not definitive od product acceptance - Skewed sample of uses - Not always efficient






44. Progressive Disclosure - Constraints






45. Task analysis - storyboarding - use cases - primary stakeholder profiles
