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. 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

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






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






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

21. Overload - Feedback - Recognition/Recall - Orientation






22. 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






23. Primary - secondary - facilitator - indirect






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






25. Location - Logical Grouping - Conventions - Redundancy






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






27. Physical - cultural - functional - informational






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






29. Goals - Execution - World - Evaluation






30. Unscientific - Partial - Unstable - Inconsistent - Personal






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






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






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






34. 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






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






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

44. Progressive Disclosure - Constraints






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






46. 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


47. Direct - indirect - ethnographic observation - distributed cognition






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