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.

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






3. 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






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






5. 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


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






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






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






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






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






11. Participants - design - tester






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






13. 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






14. Time - finance - personnel - laboratory






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






17. 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






18. Effectiveness/Usefulness 1.Utility 2.Safety(Recovery) 3.Flexibility(Customization) 4.Stability - Efficiency/Usability






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






20. 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






21. Unscientific - Partial - Unstable - Inconsistent - Personal






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






23. 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






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






25. 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






26. Comprehensibility and learnability






27. Overload - Feedback - Recognition/Recall - Orientation






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. 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






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






31. Menu options create small articulatory distance






32. 1.command line 2.menu- based interface 3.form fill- in 4.question and answers 5.direct manipulation 6.metaphors 7.web navigation 8.3d environments 9.zoomable interface 10.natural language






33. 1. Visibility of System Status 2. Match between System and the Real World 3. User Control and Freedom 4. Consistency and Standards 5. Error Prevention 6. Recognition Rather Than Recall 7. Flexibility and Efficiency of Use 8. Aesthetic and Minimalist


34. 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






35. Goals - Execution - World - Evaluation






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






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






38. 1.low memory requirements 2. self- explanatory 3.can gather a great deal of information in little space 4.present a context for input information






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






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






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






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