Canvas Navigation with a Screen Reader
Canvas makes extensive use of ARIA landmark regions. Accessible Rich Internet Applications (ARIA) defines ways to make web content and web applications more accessible to people with disabilities. Therefore, the best way to get around in Canvas is to navigate via regions. Within regions, Canvas uses HTML headings, so navigating between headings can be helpful.
When using a screen reader, the Canvas page navigation menu is as follows:
1. Main navigation
2. Context navigation
3. Breadcrumbs navigation
4. Main region
5. Complimentary information
6. Content information

- Headings for table columns and rows can be changed in either the Rich Content Editor or the HTML Editor view.

User Settings. The User Settings page hosts a feature option called a High Contrast Style. When enabled, this feature offers higher contrast in buttons, tabs, and other areas throughout Canvas. Learn how to change user settings.

SpeedGrader/DocViewer/Annotations: Students can now access annotations and comments with a screen reader, including information about the annotation type, author name, comment, and any reply comments at the end of the document. Please see blog post for more information.
Accessibility of Third-party (LTI) Integrations
Some integrations are non-optional hosted services within Canvas. Any accessibility issues for Canvas-hosted services should be submitted as a help ticket via the institution's support process. We are open to suggestions for new integrations and have an area in the Canvas Help Forums forums for feature requests.
