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.

10. 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






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






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






13. 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






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






15. 1. speech recognition 2. semantic - grammar issues - vague meanings - contradictory statement






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






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






18. Direct - indirect - ethnographic observation - distributed cognition






19. 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






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






21. 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






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






23. Goals - Execution - World - Evaluation

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






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






28. 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






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






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






31. 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
