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

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






13. Progressive Disclosure - Constraints






14. User interface independence 1.They separate interface design from internals 2.They enable multiple user interface strategies 3. They enable multiple platform support 4. They establish the role of the user interface architect 5. They enforce standards






15. Unscientific - Partial - Unstable - Inconsistent - Personal






16. 1.They facilitate the development of design procedures 2.They help in finding ways to talk about design 3.They create project management

18. Location - Logical Grouping - Conventions - Redundancy






19. They are not interactive - They cannot be used to calculate response timings - They do not deal with interface issues such as color or font size






20. Articulatory distance is large because we are presented with the command prompt - no indication of functionality






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






22. 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






23. Establishing the goal - Forming the intention - Specifying the action sequence - Execute the action sequence - Perceiving the world state - Interpreting the perception - Evaluate the interpretation

28. 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






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