Scenario Planning ,[object Object],WAI Approach Scenario 1 Holistic Accessibility Scenario 2 Accessibility 3.0 Scenario 3

WAI Approach ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],WAI’s Approach Also note importance of evidence-based research . Various UK accessibility studies seem to find that lack of evidence of accessibility of Web sites for PWDs and conformance with WCAG guidelines!

WCAG In Context ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Legislation: “take reasonable measure ..” Is bankrupting your company reasonable? Is failing to satisfy your user community reasonable? Is dumbing down the English language reasonable? WAI’s Scenario

Holistic Approach ,[object Object],[object Object],[object Object],[object Object],Follow-up work awarded prize for Best Research Paper at ALT-C 2005 E-learning conference Holistic Scenario This approach reflects emphasis in UK on blended learning (rather than e-learning)

Articulating the Approach ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Holistic Scenario

Accessibility 2.0 ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Holistic Scenario But do scenarios 1 and 2 scale to the size, complexity and diversity of today’s Web?

Where Are We In This View? Web WCAG Web IT ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],The Pixel of Perfection The Holistic Hamlet WAI

Accessibility 1.0, 2.0 and 3.0 ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Accessibility 3.0 Scenario

A Fresh Look At Accessibility ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Accessibility 3.0 Scenario

Getting There ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Accessibility 3.0 Scenario

Alternative Resources ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Accessibility 3.0 Scenario

Library Standards on Alternatives ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Accessibility 3.0 Scenario Recognition of challenges of the multiple standardisation routes described in “ Personalization and Accessibility: Integration of Library and Web Approaches ”, Chapman, Nevile, Kelly and Heath

Web 3.0 ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],“ Its not the Social Network Sites that are interesting - it is the Social Network itself. The Social Graph. The way I am connected, not the way my Web pages are connected. ” Tim Berners-Lee Accessibility 3.0 Scenario

Semantic Approach ,[object Object],[object Object],[object Object],[object Object],“ I express my network in a FOAF file, and that is a start of the revolution. … It is about getting excited about connections, rather than nervous. ” Tim Berners-Lee Accessibility 3.0 Scenario

Accessibility 3.0 ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Accessibility 3.0 Scenario Challenge: Can such developments be applied to provide benefits to people with disabilities?

Initial Experiments ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Semantic Web Principles ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Learning From The Past ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Accessibility 3.0 Scenario Note that the Accessibility 3.0 vision is based on W3C Semantic Web principles. A challenge for W3C and user community is reconciling WAI and SW visions and how they are interpreted.

Conclusions ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],But can this view be sold to organisations, governments and individuals who have bought a the view of WAI delivering “ the answer”? These conclusions are aimed at the accessibility researchers and practitioners to persuade them that a rethink is needed

Another Interpretation ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
