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.

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






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






18. 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


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






20. 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






21. 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






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






23. 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






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






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

27. 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






28. Unscientific - Partial - Unstable - Inconsistent - Personal






29. Overload - Feedback - Recognition/Recall - Orientation






30. They can be used early and often - They are inexpensive and easy to create - They make design idea visual - No special knowledge is required - all team members can create them






31. 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






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. Location - Logical Grouping - Conventions - Redundancy






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






35. Participants - design - tester






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






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






38. 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
