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






13. 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






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






15. 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






16. Easy and inexpensive to make - Flexible enough to be constantly changed and rearranged - Complete enough to yield useful feedback about specific design questions






17. Overload - Feedback - Recognition/Recall - Orientation






18. Minimize help desk calls - increase product loyalty - Provide benchmarks for future products






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






20. 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






21. 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






22. 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






23. Goals - Execution - World - Evaluation






24. Location - Logical Grouping - Conventions - Redundancy






25. Progressive Disclosure - Constraints






26. 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






27. 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


28. Observation - elicitation






29. Unscientific - Partial - Unstable - Inconsistent - Personal






30. 1.require valid input in valid format 2.require familiarity with interface control 3.can be tedious to correct mistakes






31. 1.ease of learning - 2.low memory requirement - 3.flexible interaction - 4.low screen requirement - 5. sppropriate for beginner






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






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






34. 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






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






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






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






38. 1.low command retention 2. steep learning curve 3.high error rates 4.heavy reliance on memory 5.frustrating for novice users






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






40. 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






41. Structuring the information space - Creating of alternative solutions - Determining which design concept to purse






42. 1.command line 2.menu- based interface 3.form fill- in 4.question and answers 5.direct manipulation 6.metaphors 7.web navigation 8.3d environments 9.zoomable interface 10.natural language
