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






17. 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






18. Comprehensibility and learnability






19. Primary - secondary - facilitator - indirect






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






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






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






23. Overload - Feedback - Recognition/Recall - Orientation






24. 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






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






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

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






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






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






41. Participants - design - tester






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