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.
1. 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

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






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






15. 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






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

29. 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






30. The range of possible intentions is consistently wide - users usually have multiple options for specifying action sequences - provide multiple ways of executing action sequence






31. Low- fidelity prototypes - Evaluations - Wireframes - Functional prototypes






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