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.

9. Direct indirect - corporate documentation - logs and notes - questionnaires






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






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






12. 1. the people who are involved with the work 2. the things they use to do the work - 3. the process that are involved in the work - 4. the information required to do the work - 5. the constraints imposed on the work - 6. the inputs required by the wo

17. 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






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






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






20. Physical - cultural - functional - informational






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






22. Location - Logical Grouping - Conventions - Redundancy






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






24. 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






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






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






27. Observation - elicitation






28. 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






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






30. 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






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






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






33. 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






34. They can be used early and often - They are inexpensive and easy to create - They make design idea visual - No special knowledge is required - all team members can create them






35. Unscientific - Partial - Unstable - Inconsistent - Personal






36. 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






37. Time - finance - personnel - laboratory






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






39. 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






40. 1. Visibility of System Status 2. Match between System and the Real World 3. User Control and Freedom 4. Consistency and Standards 5. Error Prevention 6. Recognition Rather Than Recall 7. Flexibility and Efficiency of Use 8. Aesthetic and Minimalist


41. Progressive Disclosure - Constraints






42. 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






43. Menu options create small articulatory distance
