Accessibility vs. Usability
What’s the difference?
- Accessibility = ACCESS to information and services
- Usability = Ease of use
Ideally, the two would be combined.
Why is this important to government?
Section 508 of the US Rehabilitation Act is a statute that applies to federal agencies when they develop, procure, maintain, or use electronic and information technology. Under Section 508, agencies must give disabled employees and members of the public access to information that is comparable to the access available to others.
