The W3C has published guidelines for accessibility of web pages in order to enable many disabled users to use them. These are known as the WAI guidelines. For more details see our Technical Info Page. But its just a start. Since there are some important aspects of accessible Web page design that can not yet be tested by Bobby, CAST recommends that Web developers use Bobby only as a first step to ensure accessible Web page design.
Accessibility is ultimately a human endeavor.
It is determined by whether or not a diverse group of people with a variety of abilities and disabilities can access information efficiently. Bobby helps to make web pages more accessible, but can not guarantee total accessibility. It sees a table but it does not know if its being used for layout, which may make it inaccessible. Text versions are usually out dated. Main sites are often updated while the text version is forgotten about.
