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.
1. 1. suitable for repetitive tasks 2. sdvantageous for expert users 3.offer direct access to system functionality 4.efficient and powerful 5.not encumbered with graphic controls - low visual load - not taxing on system resource 6. scriptable

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






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






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






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






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






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






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






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






11. Participants - design - tester






12. 1.require knowledge of the task domain - 2.may require tedious clarification dialogues - 3.complex system development






13. Progressive Disclosure - Constraints






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






15. 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






16. 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






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






18. 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






19. 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






20. 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






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






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






23. Effectiveness/Usefulness 1.Utility 2.Safety(Recovery) 3.Flexibility(Customization) 4.Stability - Efficiency/Usability






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

27. 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






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






29. Gulfs of execution relate to the effectiveness principle - Gulfs of evaluation relate to the efficiency principle






30. Goals - Execution - World - Evaluation






31. 1.easy to learn2.low memory requirements 3.easy to undo 4.immediate feedback to user actions 5.enable user to use spatial cues 6.easy for beginner






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






33. 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






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






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






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






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






38. 1.rapid and inflexible navigation 2.inefficient for large menu navigation 3.inefficient use of screen real estate 4. slow for expert






39. Direct - indirect - ethnographic observation - distributed cognition






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






41. 1. speech recognition 2. semantic - grammar issues - vague meanings - contradictory statement






42. 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
