Instructions provided for understanding and operating content do not rely solely on sensory characteristics of components such as shape, color, size, visual location, orientation, or sound.



The purpose of this success criterion is to ensure that users do not have to perceive the content to follow any instructions.

How to Meet

To meet this success criterion, any instructions must not rely on the user being able to perceive the sensory characteristics of the content.

For example, the instructions to perform an experiment must not caution users that steps in "red" are potentially dangerous. You should also label the steps. Similarly, instructions for playing interactive games and animations must not describe controls only by their appearance.
