Test your basic knowledge |

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.

27. 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






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. Physical - cultural - functional - informational






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

39. 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






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






41. 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
