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.

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






16. Observation - elicitation






17. Artificial context - Not definitive od product acceptance - Skewed sample of uses - Not always efficient






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






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

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






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






28. Time - finance - personnel - laboratory






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

40. 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






41. Brainstorming - Card sort - Semantic Networks - Personas - Scenarios - Flowcharts - Cognitive walkthrough - Use cases






42. Easy and inexpensive to make - Flexible enough to be constantly changed and rearranged - Complete enough to yield useful feedback about specific design questions
