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. Consistency-Correctness - Generalizability - Conventions - Familiarity - Location - Modes






2. 1.language is ambiguous 2.meaning depends on context 3.dependent on visual cues

6. 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






7. 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






8. 1.not self- explanatory 2.inefficient use of screen real estate 3.high graphical system requirements






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






10. 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






11. Functionality->presentation filter | (comprehensibility barrier)| efficiency usability ->|(learnability barrier) | Effectiveness Usefulness






12. 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


13. 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






14. 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






15. 1.require valid input supplied by user 2.require familiarity with interface control 3.can be tedious to correct mistakes






16. Time - finance - personnel - laboratory






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






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






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






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






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






22. Observation - elicitation






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






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






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






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






27. Primary - secondary - facilitator - indirect






28. They are quick and easy to create - They provide a consistent model for all team members - They are easy to use with other design methods - They make the user real in the mind of the designer






29. 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






30. Physical - cultural - functional - informational






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






32. Determine the function of the device - Determine what actions are possible - Determine mapping from intention to physical movement - Perform the action - Determine whether the system is in the desired state - Determine the mapping from system state t






33. 1.command line 2.menu- based interface 3.form fill- in 4.question and answers 5.direct manipulation 6.metaphors 7.web navigation 8.3d environments 9.zoomable interface 10.natural language






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






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






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






37. 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






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. 1.require valid input in valid format 2.require familiarity with interface control 3.can be tedious to correct mistakes






40. 1.low command retention 2. steep learning curve 3.high error rates 4.heavy reliance on memory 5.frustrating for novice users






41. 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






42. Use multiple independent evaluators - Use observer to record evaluator - Go through interface several times - Compare interaction against list of heuristics - Use heuristics specific to design - List heuristic problems and how the heuristic is violat
