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.

16. 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






17. Participants - design - tester






18. Direct - indirect - ethnographic observation - distributed cognition






19. Determine the function of the device - Determine what actions are possible - Determine mapping from intention to physical movement - Perform the action - Determine whether the system is in the desired state - Determine the mapping from system state t






20. 1. speech recognition 2. semantic - grammar issues - vague meanings - contradictory statement






21. They allow an easy way to explore the problem space - They provide a way to create clusters of related elements - They provide a graphical view of the problem space - They resonate with the ways in which people process information






22. 1.language is ambiguous 2.meaning depends on context 3.dependent on visual cues






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






24. Graphical libraries - User interface toolkits - Visual interface builders - Web development tools






25. They are quick and easy to perform - They can be done before any preliminary designs have been made - They will let you know how people organize information - They will expose underlying structures






26. Comprehensibility and learnability






27. User interface independence 1.They separate interface design from internals 2.They enable multiple user interface strategies 3. They enable multiple platform support 4. They establish the role of the user interface architect 5. They enforce standards






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






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






30. Menu options create small articulatory distance

32. Gulfs of execution relate to the effectiveness principle - Gulfs of evaluation relate to the efficiency principle






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