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.

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






13. Direct - indirect - ethnographic observation - distributed cognition






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






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






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. Unscientific - Partial - Unstable - Inconsistent - Personal






18. 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
