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






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

4. 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






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






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






7. 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






8. Primary - secondary - facilitator - indirect






9. 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






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






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






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






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






14. 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






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






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






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






18. Time - finance - personnel - laboratory






19. 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






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






21. Comprehensibility and learnability






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






23. 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


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






25. Physical - cultural - functional - informational






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






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






28. 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


29. 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






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






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






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






33. Goals - Execution - World - Evaluation






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






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






36. 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






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






38. They can be difficult to create f the target audience is international - Having too many personas will make the work difficult - There is a risk of incorporating unsupported designer assumption






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






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






41. 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






42. 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






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