What is Accessibility?

Accessibility involves two key issues:

How users with disabilities access
electronic information

How content designers, developers,
and authors produce content that
functions with assistive devices used by
individuals with disabilities.

Accessibility is not a feature, it’s
about procedures, processes, and
techniques

There is NO Accessibility Button –
Accessible Content Creation is a

Achieving Accessibility Requires
Human Testing in addition to
Automated Checking
Checking Can Only Detect for the
Presence or Lack of Required Items
Cannot Check if an Item is Correct or
Appropriate
Accessibility is a New Item for the
Production Workflow – Like
Authoring, Layout, Proofreading, etc.
Note Also, Publishers Will Need to
Employ a Variety of Techniques and
Methods
