WCAG 4.1.3 - Quick Reference
When using a screen reader or other assistive technology devices, is the user alerted to important content changes without interrupting their work?
Sighted users can observe and interact with visible content changes or updates on the screen (e.g. error messages, progress bars, shopping carts). People who are blind or have low vision using assistive technology might not be aware of these changes. To be accessible, status messages alert assistive technology users to these changes without moving focus away from their current location on the screen. This allows them to hear the changes or updates being made without interrupting their work or disorienting them on the page.
As a student with low vision who purchases textbooks online,
I want my screen reader to announce when I add an item to my shopping cart
so that I can hear it has been added.
As a student who is blind using a screen reader,
I want to hear immediate feedback if I enter incorrect information into a form field
so that I can correct it right away.
Ensure people who use screen readers and other assistive technology devices are aware of changing content that is happening on the screen but does not distract or interrupt their work.
