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. Unscientific - Partial - Unstable - Inconsistent - Personal






16. 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






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






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






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






21. Observation - elicitation






22. Physical - cultural - functional - informational






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






24. Menu options create small articulatory distance






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






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






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

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






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






35. Participants - design - tester






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






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






38. Primary - secondary - facilitator - indirect






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






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






41. 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






42. Location - Logical Grouping - Conventions - Redundancy






43. 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
