Cards in this deck (13)
- 1Explain why cognitive walkthroughs are considered discount usability methodsCheap, fast, easy to use
- 2What are the pros and cons of cognitive walkthroughs?Pros: Cheap, fast, easy to use, helps work out task sequence models through observation
Cons: Limited utility for frequent-use interfaces, narrow focus, relatively time consuming and laborious - 3When are cognitive walkthroughs an appropriate choice of evaluation method?When assessing how well a new user will be able to figure out the interface.
Not for performance at highly skilled, frequently performed tasks or finding radically new approaches - 4What can cognitive walkthroughs assess?How well a new user will be able to figure out the interface
- 5Give the general procedure of a cognitive walkthroughStart with a Scenario (task example + design)
-Break task into user actions & expected system response
-Perform each step on the existing interface and ask (will user know what to do, will user see how to do it, will user correctly understand the system response)
-If you locate a problem, mark it, and continue on as if it weren't an issue - 6Why prototype?-Communication (discuss ideas with stakeholders)
-Develop requirements
-Learning/problem solving
-Evaluate interface effectiveness for communicating conceptual model
-Develop conceptual and physical design
-Save time and money - 7When to prototype?Functionality?
Appearance?
Specifications? - 8When are usability studies typically conducted?-On refined prototypes to test how well an interface supports test execution
- 9Why are usability studies conducted?-Test a relatively refined prototype in support of task execution
- 10What is a heuristic evaluation?Fine-tunes interface
Targets broader use range
HCI professionals apply a list of heuristics while simulating task execution - 11Why is heuristic evaluation considered a discount usability method?Cheap, fast, easy to use
- 12Describe steps involved in conducting heuristic evaluationsDesign team supplies scenarios, prototype, list of heuristics
Each elevator independently produces a list of justified, rated problems by stepping through interface and applying heuristics at each point
Team meets and compiles report that organizes and categorizes problems - 13Describe pros and cons of heuristic evaluationsPros:
Contributes valuable insights from objective observers
The minimalist approach
Discount
Cons:
-Principles must be applied intuitively and carefully
-Heuristics can narrow focus at the cost of other problems
-Can reinforce existing design
-Doesn't predict customer satisfaction necessarily
-May not have same credibility as user test data
