Technique G95:Providing short text alternatives that provide a brief description of the non-text content

Applicability

Applies to all technologies

This technique relates to 1.1.1: Non-text Content (Sufficient).

Description

This technique is used when the text needed to serve the same purpose and present the same information as the original non-text content is too lengthy or when this goal cannot be achieved with text alone. In that case this technique is used to provide a short text alternative that briefly describes the non-text content. (A long text alternative is then provided using another technique such that the combination serves the same purpose and presents the same information as the original non-text content.)

In deciding what text to include in the alternative, it is often a good idea to consider the following questions:

• Why is this non-text content here?
• What information is it presenting?
• What purpose does it fulfill?
• If I could not use the non-text content, what words would I use to convey the same function and/or information?

Examples

• A chart showing sales for October has an short text alternative of "October sales chart". It also has a long description that provides all of the information on the chart.
