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.

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






6. 1.low memory requirement 2. self- explanatory 3. simple linear presentation 4.easy for beginner






7. 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






8. Progressive Disclosure - Constraints






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






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. 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






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






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






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






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






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






17. 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






18. Goals - Execution - World - Evaluation






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






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






21. 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






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






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






24. 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






25. Observation - elicitation






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






27. Participants - design - tester






28. 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






29. 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






30. Unscientific - Partial - Unstable - Inconsistent - Personal






31. Physical - cultural - functional - informational






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






33. 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






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






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






37. Comprehensibility and learnability






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






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

41. 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






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






43. 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
