Week 6 Flashcards
(15 cards)
When in the development lifecycle is lab-based usability testing most effective?
Early and repeatedly - use paper prototypes in the early stage, compare UI designs in the middle, and certify usability in later stages.
What’s the “Lost-Our-Lease” approach to testing?
A quick, cheap, informal usability test done often instead of expensive scientific studies.
Name three benefits of conducting multiple usability tests.
Catches issues early, tracks improvements over time, and reduces risks of major redesigns later.
Describe the ideal setup of a lab-based usability study room.
Quiet room with computer, participant at workstation, moderator guiding tasks, observers behind one-way mirror or via webcam.
How many participants are recommended for a basic usability test, and why?
At least 3-4 “new” users; beyond that, diminishing returns on finding new usability issues.
List four types of data you might collect in a usability test.
Task completion rates (with/without help), error counts, time-on-task, and qualitative observations (comments, mannerisms)
What are key limitations of lab-based usability testing?
Artificial setting, doesn’t prove market demand, can miss long-term learnability or expert use cases.
What is “Universal Design”?
Designing products and environments to be aesthetic and usable by everyone, regardless of age, ability, or status.
Name three principles of Universal Design.
Equitable use, simple & intuitive use, perceptible information (among six total principles).
How does Inclusive Design differ from Universal Design?
Inclusive Design pragmatically acknowledges varying abilities as universal and focuses on designs that work best for all through four core premises.
What are the four WCAG principles?
Perceivable, Operable, Understandable, Robust
Under WCAG, what does “Operable” mean?
Interface components and navigation must be usable with various input methods and not require actions users cannot perform?
What major EU legislation mandates digital accessibility by June 28, 2025?
The European Accessibility Act (EAA)
What’s new in WCAG 2.2 compared to 2.1?
Expanded criteria for mobile accessibility, authentication options, and cognitive support.
Why should organisations implement WCAG 2.2 features even if not formally required?
To future-proof accessibility and ensure compliance as legal frameworks transition from WCAG 2.1 to 2.2.
