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.

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






21. Task analysis - storyboarding - use cases - primary stakeholder profiles






22. 1.run out of metaphors 2.mixed metaphors 3.carry connotations and association






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






24. Low- fidelity prototypes - Evaluations - Wireframes - Functional prototypes






25. Primary - secondary - facilitator - indirect






26. Structuring the information space - Creating of alternative solutions - Determining which design concept to purse






27. 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






28. 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






29. Effectiveness/Usefulness 1.Utility 2.Safety(Recovery) 3.Flexibility(Customization) 4.Stability - Efficiency/Usability






30. Direct indirect - corporate documentation - logs and notes - questionnaires






31. 1. suitable for repetitive tasks 2. sdvantageous for expert users 3.offer direct access to system functionality 4.efficient and powerful 5.not encumbered with graphic controls - low visual load - not taxing on system resource 6. scriptable






32. 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


33. Unscientific - Partial - Unstable - Inconsistent - Personal






34. 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






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

39. Consistency-Correctness - Generalizability - Conventions - Familiarity - Location - Modes






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






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






42. Time - finance - personnel - laboratory
