User Testing Exam User Testing Accessibility and Inclusive Design 2 — Questions and Answers
Question 1: What is a 'screen reader' and how does its use affect usability testing?
- Software that captures screenshots automatically during a session
- Software that converts on-screen text and UI elements to speech or Braille output for blind users (Correct answer)
- A browser plugin that simplifies interface layouts for cognitive accessibility
- Hardware that magnifies text for users with low vision
Correct answer: Software that converts on-screen text and UI elements to speech or Braille output for blind users
Screen readers (e.g., NVDA, JAWS, VoiceOver) navigate the DOM sequentially, so usability testing with screen reader users reveals issues invisible to sighted testers.
Question 2: What is the purpose of alt text on images in accessible web design?
- To provide a tooltip shown when users hover over an image
- To convey the meaning or function of an image to screen reader users who cannot see it (Correct answer)
- To improve image loading speed on slow connections
- To tag images with metadata for search engine optimization only
Correct answer: To convey the meaning or function of an image to screen reader users who cannot see it
Alt text provides a textual equivalent of an image's meaning or function so screen reader users receive the same informational value as sighted users.
Question 3: What does 'cognitive accessibility' address in product design?
- Compatibility with cognitive computing systems like AI assistants
- Reducing mental effort required to understand, navigate, and use a product for users with cognitive disabilities (Correct answer)
- The intellectual property rights of interface designers
- Ensuring the product works across different cognitive science research platforms
Correct answer: Reducing mental effort required to understand, navigate, and use a product for users with cognitive disabilities
Cognitive accessibility focuses on minimizing cognitive load, using plain language, and providing clear structure to support users with conditions like dyslexia, ADHD, or dementia.
Question 4: What is 'focus management' in accessible web interfaces?
- Keeping participants focused during a usability test session
- Ensuring keyboard focus moves logically and is always visibly indicated on interactive elements (Correct answer)
- Managing the research team's attention during analysis
- Restricting where users can navigate within a prototype during testing
Correct answer: Ensuring keyboard focus moves logically and is always visibly indicated on interactive elements
Proper focus management ensures keyboard and assistive technology users always know where they are and can predict where focus will move next, preventing disorientation.
Question 5: In usability testing, when should accessibility testing be introduced in the development lifecycle?
- Only after the product is fully built and launched
- As early as possible, starting with wireframes and prototypes, to catch issues when they are cheapest to fix (Correct answer)
- Only when a user complaint about accessibility is received
- During the final QA phase before the scheduled release date
Correct answer: As early as possible, starting with wireframes and prototypes, to catch issues when they are cheapest to fix
Shifting accessibility testing left—to wireframes and early prototypes—prevents costly retrofitting later and embeds inclusive design into the foundation.
Question 6: What is 'captions' vs. 'subtitles' in accessible video content?
- They are identical terms used interchangeably in all US accessibility standards
- Captions include all audio content (speech and non-speech sounds) for deaf users; subtitles typically only translate speech for hearing users (Correct answer)
- Subtitles are required by WCAG; captions are optional enhancements
- Captions appear at the top of the screen; subtitles appear at the bottom
Correct answer: Captions include all audio content (speech and non-speech sounds) for deaf users; subtitles typically only translate speech for hearing users
Closed captions convey not just dialogue but also sound effects and speaker identification, making them essential for deaf and hard-of-hearing users—not just language learners.
