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.

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






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






37. 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






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






39. 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
