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.

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






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






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






9. 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






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






11. 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






12. Direct - indirect - ethnographic observation - distributed cognition






13. Speech input 1.hands - free operation 2.poor lighting situations 3.mobile application 4.in the home - speech output 5.on - board navigational systems






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






15. Goals - Execution - World - Evaluation






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






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






18. Participants - design - tester






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






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






21. 1. Visibility of System Status 2. Match between System and the Real World 3. User Control and Freedom 4. Consistency and Standards 5. Error Prevention 6. Recognition Rather Than Recall 7. Flexibility and Efficiency of Use 8. Aesthetic and Minimalist


22. Overload - Feedback - Recognition/Recall - Orientation






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






24. 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






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






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






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. 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






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






30. 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






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






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






33. 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






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






35. Physical - cultural - functional - informational






36. 1.free phase 2.captive phase 3. termination phase






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






38. Artificial context - Not definitive od product acceptance - Skewed sample of uses - Not always efficient






39. Time - finance - personnel - laboratory






40. 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






41. 1.low command retention 2. steep learning curve 3.high error rates 4.heavy reliance on memory 5.frustrating for novice users






42. Primary - secondary - facilitator - indirect






43. 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
