User capabilities  download this page as PDF

This section provides information about user capabilities such as vision, hearing, thinking and mobility. The framework section describes how these capabilities relate to a user's product experience, and explains how population data can be interpreted and used to improve design. It also explains how the design guidance in the following sections should be interpreted.

The remaining sections examine individual capabilities. For each, the effects of capability loss and the crucial functions for product interaction are described. Then design guidance and population statistics are provided.

Note that this section breaks down "Reach & dexterity" into "Reach & stretch" and "Dexterity"; and divides "Thinking" into "Thinking" and "Communication", to match the capabilities used in the Disability Follow-up Survey.
