- Operable
- Understandable
- Robust
- Perceivable
What is mean by perceivable?
Users must be able to perceive all essential info on screen regardless of disabilities (visual, mobility, hearing, cognitive, speech
impairments etc)
perceivable examples
- Adding text alternatives to all non-decorative images and essential icons
- Adding captions, transcripts, and audio descriptions to videos.
- Ensuring colour is not the only method of conveying meaning
What is meant by operable?
- Users must be able to operate the digital interface
- The interface cannot require interaction the user cannot perform
Operable examples
- Adding keyboard and touchscreen support to all active elements.
- Ensuring slideshows and videos have all of the necessary controls available.
- Giving users enough time to fill out a form or a method to extend the time.
What is meant by understandable?
Users must be able to understand the information and how to operate the UI
Operable examples
- Writing simply—don’t use a complex word
when a simple one will do. - Ensuring your digital product has predictable
navigation. - Ensuring error messages are clear and easy to
resolve
What is meant by robust?
Ensuring that as devices and user agents evolve, the product remains accessible
Robust examples
- Testing keyboard-only navigation
- Testing with different screen reader technologies.
- Ensuring all of the content and functionality can be accessed, regardless of device size or orientation
