Best Practice 2.11 – Lists with user-initiated auto-updating (Advanced level)


For content that moves automatically for more than five seconds or is updated automatically, there needs to be a way to stop this movement and stop the content from auto-updating, blinking or scrolling. Application should provide an option for users to control and stop the auto-updating operation.

 

Before Rectification
A sample mobile application page with an information ticker.
In this example, the list is designed to update automatically with content changes, which can be very frustrating for people using screen readers.
After Rectification
A sample mobile application page with an information ticker with controls that allow automatic updates to be turned on or off.
By providing a function to turn off the auto-updating, the list contents will not be refreshed frequently and easier for persons with disabilities to access.
