Test your basic knowledge |

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.

11. Direct - indirect - ethnographic observation - distributed cognition






12. Participants - design - tester






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






14. 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






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






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






17. They are quick and easy to create - They provide a consistent model for all team members - They are easy to use with other design methods - They make the user real in the mind of the designer






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






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






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






21. Primary - secondary - facilitator - indirect






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






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






24. 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






25. 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






26. 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






27. 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






28. Goals - Execution - World - Evaluation






29. 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






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






31. 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






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






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






34. Physical - cultural - functional - informational






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

40. 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






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






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