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.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






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

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






24. Physical - cultural - functional - informational






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. 1.require knowledge of the task domain - 2.may require tedious clarification dialogues - 3.complex system development






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






28. Time - finance - personnel - laboratory

33. 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






34. 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






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






36. Menu options create small articulatory distance






37. 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
