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. Goals - Execution - World - Evaluation






16. 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






17. 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






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






19. They allow an easy way to explore the problem space - They provide a way to create clusters of related elements - They provide a graphical view of the problem space - They resonate with the ways in which people process information






20. 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






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






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






23. 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






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






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






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






27. Direct - indirect - ethnographic observation - distributed cognition

31. Consistency-Correctness - Generalizability - Conventions - Familiarity - Location - Modes






32. 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


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






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






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






36. 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






37. Observation - elicitation






38. 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






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