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.

22. 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






23. 1. speech recognition 2. semantic - grammar issues - vague meanings - contradictory statement






24. 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






25. Physical - cultural - functional - informational






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

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






30. 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






31. Time - finance - personnel - laboratory






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