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.

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






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