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






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

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






23. 1.creating descriptions of the people who do the work 2.describing the different goals involved in the work 3.documenting the work step by step 4.creating different stories about how the various aspects of the work are done 5.creating charts and diag






24. They only involve the elements that you have written on the cards - They suggest solutions that imply structure - They become difficult to navigate with more categories






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

30. Overload - Feedback - Recognition/Recall - Orientation






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






32. 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






33. 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






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






35. 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

40. Participants - design - tester






41. 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
