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.

14. Unscientific - Partial - Unstable - Inconsistent - Personal






15. 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


16. Overload - Feedback - Recognition/Recall - Orientation






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






18. 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






19. 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






20. Location - Logical Grouping - Conventions - Redundancy






21. 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






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






23. 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






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






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






26. 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






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






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






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






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






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






32. Speech input 1.hands - free operation 2.poor lighting situations 3.mobile application 4.in the home - speech output 5.on - board navigational systems






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






34. Comprehensibility and learnability






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






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






37. 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


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






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






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