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






2. They can be difficult to create f the target audience is international - Having too many personas will make the work difficult - There is a risk of incorporating unsupported designer assumption






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






4. 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

7. Effectiveness/Usefulness 1.Utility 2.Safety(Recovery) 3.Flexibility(Customization) 4.Stability - Efficiency/Usability






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






9. Gulfs of execution relate to the effectiveness principle - Gulfs of evaluation relate to the efficiency principle






10. 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






11. 1.ease of learning - 2.low memory requirement - 3.flexible interaction - 4.low screen requirement - 5. sppropriate for beginner






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. 1.require knowledge of the task domain - 2.may require tedious clarification dialogues - 3.complex system development






14. 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






15. 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






16. 1. low memory requirements 2. self- explanatory 3.easy to undo errors 4. sppropriate for beginners






17. 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






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






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






20. 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






21. Observation - elicitation






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






23. Direct - indirect - ethnographic observation - distributed cognition

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






27. Comprehensibility and learnability






28. Easy and inexpensive to make - Flexible enough to be constantly changed and rearranged - Complete enough to yield useful feedback about specific design questions






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






30. Location - Logical Grouping - Conventions - Redundancy






31. 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






32. 1. suitable for repetitive tasks 2. sdvantageous for expert users 3.offer direct access to system functionality 4.efficient and powerful 5.not encumbered with graphic controls - low visual load - not taxing on system resource 6. scriptable
