Test your basic knowledge |

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. We respond first to the intensity of a stimulus and only then do we begin to process its meaning






2. 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






3. 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






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

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






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






13. 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






14. 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






15. Goals - Execution - World - Evaluation






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

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






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






21. 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






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






23. 1.rapid and inflexible navigation 2.inefficient for large menu navigation 3.inefficient use of screen real estate 4. slow for expert






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






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






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






27. 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






28. Progressive Disclosure - Constraints






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






30. Physical - cultural - functional - informational






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






32. Unscientific - Partial - Unstable - Inconsistent - Personal






33. Primary - secondary - facilitator - indirect






34. Comprehensibility and learnability






35. 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






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






37. Observation - elicitation
