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.

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






19. Observation - elicitation






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






21. Progressive Disclosure - Constraints






22. Use multiple independent evaluators - Use observer to record evaluator - Go through interface several times - Compare interaction against list of heuristics - Use heuristics specific to design - List heuristic problems and how the heuristic is violat

23. Comprehensibility and learnability






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. They are quick and easy to create - They provide a consistent model for all team members - They are easy to use with other design methods - They make the user real in the mind of the designer






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

29. 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






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






31. 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






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