Accessibility & Universal Design (40%) Flashcards
Distinguish between individual accommodations and Universal Design.
What is the difference between accessibility, usability, and universal design?
- Accessibility: design so people with disabilities have equivalent UX without barriers or discrimination
- Usability: Emphasizes ease of use and user experience, doesn’t always consider needs of people with disabilities
- Universal Design: makes products, environments, and services usable for everyone (as many as possible) w/o adaptations
What is the relationship between accessibility, usability, and universal design (UD)?
UD is closely related to accessibility & usability. All want to make products & services easier to use for everyone regardless of ability, but each emphasize different aspects.
- Acc: PWD have equivalent UX w/o barriers or discrimination
- Usability: Emphasizes ease of use and UX, but doesn’t always consider PWD’s needs
- UD: include everyone (as many as possible) w/o specifying target groups
What is the difference between universal design and accommodations?
- Universal Design: makes products, environments, and services usable for everyone (as many as possible) w/o adaptations
- Accommodations: Individual assistance provided to persons with disabilities
Universal design is a ____ approach, while accommodations are a ____ approach.
Proactive vs. Reactive

What is web accessibility?
According to the World Wide Web Consortium (W3C)
“Websites, tools, and technologies are designed and developed so people with disabilities can use them.
More specifically, people can perceive, understand, navigate, and interact with and contribute to the web.
What 4 guidelines make web content Perceivable?
- 1.1 Text Alternatives: Provide text alternatives for non-text content
- 1.2 Time-based Media: Captions & other alternatives for multimedia
- 1.3 Adaptable: Content can be presented in different ways (including by AT) without losing meaning
- 1.4 Distinguishable: Make content easier to see and hear.
What 5 guidelines make web content Operable?
- 2.1: Keyboard Accessible: Functionality is available via keyboard.
- 2.2 Enough Time: Users have enough time to read & use content.
- 2.3 Seizures & Physical Reactions: Content does not cause seizures or physical reactions.
- 2.4 Navigable: Users can easily navigate, find content, and determine where they are.
- 2.5 Input Modalities Users can use different inputs beyond keyboard.
What 3 guidelines make web content Understandable?
- 3.1 Readable: Text is readable and understandable.
- 3.2 Predictable: Web pages/content appear and operate in predictable ways.
- 3.3 Input Assistance: Help users avoid and correct mistakes.
What guideline makes web content Robust?
- 4.1 Compatible: Maximize compatibility with current and future user tools.
