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. 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






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






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






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






18. 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

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






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






28. 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






29. Location - Logical Grouping - Conventions - Redundancy






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






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






32. 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






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






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






35. Goals - Execution - World - Evaluation






36. Menu options create small articulatory distance






37. Unscientific - Partial - Unstable - Inconsistent - Personal






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