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. Goals - Execution - World - Evaluation






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






8. Time - finance - personnel - laboratory






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






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






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






13. 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


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






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






16. 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






17. Comprehensibility and learnability






18. 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






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






20. 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






21. 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






22. Direct - indirect - ethnographic observation - distributed cognition






23. Overload - Feedback - Recognition/Recall - Orientation






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






25. 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






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






27. Menu options create small articulatory distance






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






29. 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






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. 1.language is ambiguous 2.meaning depends on context 3.dependent on visual cues






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. 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






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






35. Progressive Disclosure - Constraints






36. Physical - cultural - functional - informational






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






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






39. 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






40. Primary - secondary - facilitator - indirect






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






42. 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






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