Do we treat WAI guidelines as mandatory or inspirational? How much resources should we provide? Is the problem solvable in a distributed authoring environment and no centralised CMS? Links with the real world?

A centre of expertise in digital information managementwww.ukoln.ac.uk Universal Design Universal Design: Implies that if we make use of appropriate design principles resources will then be universally accessible and reusable We may feel that if we have difficulties implementing this we are doing something wrong But: Web browsers have bugs We have little control over the output of Web authoring tools Web specs themselves have bugs, ambiguities, etc.

A centre of expertise in digital information managementwww.ukoln.ac.uk Costs Have you estimated the costs for dealing with accessibility on large Web sites: The costs of running automated tests The costs of manual tests The costs of fixing problems The costs of updating workflow procedures, purchasing new tools, retraining, etc. The costs of providing support for buggy browsers such as Netscape 4 How much should you be prepared to pay?

A centre of expertise in digital information managementwww.ukoln.ac.uk Reacting To Specialist Needs React To Known Problems If a student / member of staff with disabilities reports a problem, can that specific problem be addressed? Real World Solutions If a problem is reported which is inherently inaccessible (e.g. 3D visualisation of a molecule) rather than trying to fix the Web site, can a real world alternative be provided? Accessibility Lab Rather than designing Web sites for broken browsers can an accessibility Lab be provided, which provides standards-compliant browsers plus a range of accessibility devices?

A centre of expertise in digital information managementwww.ukoln.ac.uk Is Legislation Appropriate?
