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. 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


17. 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






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






19. 1.not self- explanatory 2.inefficient use of screen real estate 3.high graphical system requirements






20. 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






21. 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






22. 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






23. 1.command line 2.menu- based interface 3.form fill- in 4.question and answers 5.direct manipulation 6.metaphors 7.web navigation 8.3d environments 9.zoomable interface 10.natural language

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






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






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






28. 1.ease of learning - 2.low memory requirement - 3.flexible interaction - 4.low screen requirement - 5. sppropriate for beginner






29. Unscientific - Partial - Unstable - Inconsistent - Personal






30. Menu options create small articulatory distance






31. Establishing the goal - Forming the intention - Specifying the action sequence - Execute the action sequence - Perceiving the world state - Interpreting the perception - Evaluate the interpretation






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






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






34. Time - finance - personnel - laboratory






35. Primary - secondary - facilitator - indirect






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






37. Direct - indirect - ethnographic observation - distributed cognition






38. 1.low memory requirements 2. self- explanatory 3.can gather a great deal of information in little space 4.present a context for input information






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






40. 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






41. We respond first to the intensity of a stimulus and only then do we begin to process its meaning
