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. 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






10. Progressive Disclosure - Constraints






11. Observation - elicitation






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






13. 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


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






15. Participants - design - tester






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






17. Speech input 1.hands - free operation 2.poor lighting situations 3.mobile application 4.in the home - speech output 5.on - board navigational systems






18. 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






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






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






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






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






23. 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






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






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






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






27. Time - finance - personnel - laboratory






28. 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






29. Physical - cultural - functional - informational






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






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






32. 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






33. Direct - indirect - ethnographic observation - distributed cognition






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






35. Minimize help desk calls - increase product loyalty - Provide benchmarks for future products






36. 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






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






38. 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


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






40. 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






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






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






43. 1.low memory requirements 2. self- explanatory 3.can gather a great deal of information in little space 4.present a context for input information






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