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.

15. Time - finance - personnel - laboratory






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






17. 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






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






19. Direct - indirect - ethnographic observation - distributed cognition






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






21. 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






22. Participants - design - tester






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






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






26. 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






27. 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






28. 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






29. Goals - Execution - World - Evaluation






30. Speech input 1.hands - free operation 2.poor lighting situations 3.mobile application 4.in the home - speech output 5.on - board navigational systems






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






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






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






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






35. 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






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






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






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






39. Physical - cultural - functional - informational
