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.

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






3. 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






4. Progressive Disclosure - Constraints






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






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






7. 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






8. 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






9. 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


10. Location - Logical Grouping - Conventions - Redundancy






11. 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. 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






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






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






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






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






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






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






19. 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






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






21. Unscientific - Partial - Unstable - Inconsistent - Personal






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






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






24. Menu options create small articulatory distance






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






26. 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






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






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






29. 1.free phase 2.captive phase 3. termination phase






30. Goals - Execution - World - Evaluation






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






32. 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






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






34. Primary - secondary - facilitator - indirect






35. Physical - cultural - functional - informational
