Principles of digital accessibility

Perceivable

People can access the content regardless of which senses they use. Content is available via sight, hearing, and touch.

Operable

People can interact with the content regardless of abilities or the technologies they use.

Understandable

People have enough information to use and understand the content.

Robust

Content is built so that various devices and tools designed for people with disabilities can all work together.

How do I follow these principles?

Technical standards like Web Content Accessibility Guidelines provide guidance on how to create digital content that is more accessible to people with disabilities. 

Following the technical standards builds an important foundation for digital accessibility, but these standards cannot guarantee that no one will ever encounter an accessibility barrier. Just as important is to keep open lines of communication. Encourage people to report accessibility barriers, and be aware of UTHealth Houston resources that can help address them.
