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.

9. Comprehensibility and learnability






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






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






12. 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






13. Menu options create small articulatory distance






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






15. Observation - elicitation






16. 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






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






18. 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






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






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






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






22. 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






23. 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






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






25. 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






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






27. 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






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






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






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






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






32. Goals - Execution - World - Evaluation






33. 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
