Test your basic knowledge |

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.

14. Goals - Execution - World - Evaluation






15. 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


16. Direct - indirect - ethnographic observation - distributed cognition






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






18. Time - finance - personnel - laboratory






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






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






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






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






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






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






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






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






27. 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






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






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






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






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






32. Unscientific - Partial - Unstable - Inconsistent - Personal






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






34. 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






35. 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






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






37. Primary - secondary - facilitator - indirect






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






39. Participants - design - tester






40. 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






41. They are quick and easy to create - They provide a consistent model for all team members - They are easy to use with other design methods - They make the user real in the mind of the designer






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






43. Consistency-Correctness - Generalizability - Conventions - Familiarity - Location - Modes






44. Observation - elicitation






45. Overload - Feedback - Recognition/Recall - Orientation






46. 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






47. 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






48. 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






49. 1.language is ambiguous 2.meaning depends on context 3.dependent on visual cues
