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. 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






12. Direct - indirect - ethnographic observation - distributed cognition






13. 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

22. Time - finance - personnel - laboratory






23. 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






24. Ease of Learning - Efficiency of use - Memorability - Error frequency and severity - Subjective satisfaction






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






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






27. 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






28. 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






29. Use multiple independent evaluators - Use observer to record evaluator - Go through interface several times - Compare interaction against list of heuristics - Use heuristics specific to design - List heuristic problems and how the heuristic is violat


30. 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






31. 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






32. 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






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






34. Observation - elicitation






35. Direct indirect - corporate documentation - logs and notes - questionnaires






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






37. 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






38. Progressive Disclosure - Constraints

41. 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






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