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.

7. Task analysis - storyboarding - use cases - primary stakeholder profiles






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

12. Goals - Execution - World - Evaluation






13. They increase productivity - They offer constraint and consistency checks - They facilitate team approaches - They ease maintenance






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






15. Participants - design - tester






16. Artificial context - Not definitive od product acceptance - Skewed sample of uses - Not always efficient






17. Primary - secondary - facilitator - indirect






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






19. Ease of Learning - Efficiency of use - Memorability - Error frequency and severity - Subjective satisfaction






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






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






22. We respond first to the intensity of a stimulus and only then do we begin to process its meaning






23. 1.low memory requirement 2. self- explanatory 3. simple linear presentation 4.easy for beginner






24. 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






25. 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

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






29. 1.creating descriptions of the people who do the work 2.describing the different goals involved in the work 3.documenting the work step by step 4.creating different stories about how the various aspects of the work are done 5.creating charts and diag






30. Structuring the information space - Creating of alternative solutions - Determining which design concept to purse

35. Comprehensibility and learnability






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






37. Progressive Disclosure - Constraints






38. 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






39. 1.run out of metaphors 2.mixed metaphors 3.carry connotations and association






40. They allow an easy way to explore the problem space - They provide a way to create clusters of related elements - They provide a graphical view of the problem space - They resonate with the ways in which people process information
