G82: Providing a text alternative that identifies the purpose of the non-text content


Applies to all technologies

This technique relates to:


The purpose of this technique is to provide useful information via the text alternative even if the full function of the non-text content cannot be provided.

Sometimes, a text alternative cannot serve the same purpose as the original non-text content (for example an applet meant to develop two dimensional rapid targeting skills and eye hand coordination.) In these cases this technique is used. With this technique a description of the purpose of the non-text content is provided.


Example 1


Resources are for information purposes only, no endorsement implied.



  1. remove, hide, or mask the non-text content

  2. replace it with the text alternative

  3. check that the purpose of the non-text content is clear - even if function is lost.
