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.

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






9. 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






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






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






12. Goals - Execution - World - Evaluation






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






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






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






16. 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


17. Overload - Feedback - Recognition/Recall - Orientation






18. 1.free phase 2.captive phase 3. termination phase






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






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






21. Direct - indirect - ethnographic observation - distributed cognition






22. 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






23. 1.require knowledge of the task domain - 2.may require tedious clarification dialogues - 3.complex system development






24. Observation - elicitation






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






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






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






28. 1.require valid input in valid format 2.require familiarity with interface control 3.can be tedious to correct mistakes






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

31. Participants - design - tester






32. 1.low memory requirement 2. self- explanatory 3. simple linear presentation 4.easy for beginner






33. Translating the user's task language into the input language requires knowledge of the core language - The output language can be confusing for inexperienced users - there is very little feedback






34. Progressive Disclosure - Constraints






35. Direct indirect - corporate documentation - logs and notes - questionnaires






36. Establishing the goal - Forming the intention - Specifying the action sequence - Execute the action sequence - Perceiving the world state - Interpreting the perception - Evaluate the interpretation






37. 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






38. 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






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






40. Physical - cultural - functional - informational






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






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






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






44. 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






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






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






47. 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
