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.

10. 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






11. Menu options create small articulatory distance






12. Physical - cultural - functional - informational






13. Ease of Learning - Efficiency of use - Memorability - Error frequency and severity - Subjective satisfaction






14. 1.require valid input supplied by user 2.require familiarity with interface control 3.can be tedious to correct mistakes






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






16. What it will look like - What components it will require - How the screens will be laid out






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






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






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






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






21. 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






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






23. Observation - elicitation






24. 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






25. Overload - Feedback - Recognition/Recall - Orientation






26. 1.They facilitate the development of design procedures 2.They help in finding ways to talk about design 3.They create project management






27. 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


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






29. Translating the user's task language into the input language requires knowledge of the core language - The output language can be confusing for inexperienced users - there is very little feedback






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






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






32. 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






33. Primary - secondary - facilitator - indirect






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






35. 1. the people who are involved with the work 2. the things they use to do the work - 3. the process that are involved in the work - 4. the information required to do the work - 5. the constraints imposed on the work - 6. the inputs required by the wo






36. They increase productivity - They offer constraint and consistency checks - They facilitate team approaches - They ease maintenance






37. 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






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






39. Progressive Disclosure - Constraints






40. 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






41. 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






42. 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
