En How web accessibility affects people with autism explican:
The Web Content Accessibility Guidelines (WCAG) 2.0 are the most popular standard for web accessibility, and have been cited by the U.S. Department of Justice as an acceptable metric for compliance with the Americans with Disabilities Act. WCAG 2.0 contains several guidelines to help people with four different classes of disabilities: vision, hearing, motor, and cognitive.
People on the autism spectrum have a wide range of conditions, and many of them can face difficulties with cognition when using the internet. Some of the most relevant WCAG 2.0 recommendations for people with autism are:
- Navigation and layout should be consistent across the entire site. Performing the same or similar actions on similar user interface elements should produce similar results.
- The site should still be usable at larger text sizes and should still function with images and styles disabled. However, images, icons, and graphics that help with comprehension can be included.
- Clutter and distractions should be minimized. Style and white space should separate content and direct the user’s attention as appropriate.
- The text should be as simple as possible, while providing definitions for any non-standard terms, such as idioms, jargon, and abbreviations and acronyms. Correct grammar and spelling are important.
- Users should have as much control as possible over the site’s behavior. Avoid time limits on content or automatic refreshes whenever possible. Provide clear instructions and error messages when filling out forms.
