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.

20. Direct - indirect - ethnographic observation - distributed cognition






21. 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

30. 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






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






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. 1.creating descriptions of the people who do the work 2.describing the different goals involved in the work 3.documenting the work step by step 4.creating different stories about how the various aspects of the work are done 5.creating charts and diag

35. 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






36. Time - finance - personnel - laboratory






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






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