Human Computer Interaction

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.

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

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






24. Unscientific - Partial - Unstable - Inconsistent - Personal






25. They are quick and easy to create - They provide a consistent model for all team members - They are easy to use with other design methods - They make the user real in the mind of the designer






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






27. Time - finance - personnel - laboratory






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

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






40. 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






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






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






43. 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
