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

6. 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






7. Observation - elicitation






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






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






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






11. 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






12. Gulfs of execution relate to the effectiveness principle - Gulfs of evaluation relate to the efficiency principle






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






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






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






16. 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






17. Primary - secondary - facilitator - indirect






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






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






20. 1. low memory requirements 2. self- explanatory 3.easy to undo errors 4. sppropriate for beginners






21. Progressive Disclosure - Constraints






22. 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






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






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






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






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






27. Menu options create small articulatory distance






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






29. 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


30. 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






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






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






33. 1.creating descriptions of the people who do the work 2.describing the different goals involved in the work 3.documenting the work step by step 4.creating different stories about how the various aspects of the work are done 5.creating charts and diag






34. 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






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






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






37. 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


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






39. Physical - cultural - functional - informational






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






41. Time - finance - personnel - laboratory






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






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