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






36. 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






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






38. Progressive Disclosure - Constraints






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






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






41. Location - Logical Grouping - Conventions - Redundancy






42. 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






43. 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
