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. 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. Goals - Execution - World - Evaluation






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






19. 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






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






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






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

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






29. 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






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






31. 1.require valid input supplied by user 2.require familiarity with interface control 3.can be tedious to correct mistakes






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






33. 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






34. 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






35. Primary - secondary - facilitator - indirect






36. 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






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






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






39. 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


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






41. Participants - design - tester
