Success criterion 3.2.5

Change on Request

Changes in context are only made upon the user's request, preventing disorientation or confusion by ensuring users have control over when changes occur.

  • Level AAA
  • Principle 3: Understandable
  • Guideline 3.2: Predictable

In a user’s words

“Don't move the ground beneath me unless I say so. Changes should happen on my cue!”

Who this helps: Cognitive Impairments, Visual Impairments

What each role can do

Product manager
Design functionality that requires explicit user action to initiate any change in context.
Designer
Ensure that user interfaces are designed to minimize unexpected changes, providing controls for users to initiate changes.
Developer
Implement mechanisms that prevent automatic context changes unless initiated by the user.
Tester
Test to ensure that context changes do not occur without user initiation or clear options to disable such changes.

Once it is fixed

“Being in control of changes makes me feel empowered and oriented. Thanks for putting me in the driver's seat!”
