Hi, It has been suggested that the <canvas> feature in HTML5 should have an accessibililty solution more thorough that its current solution, which is based on the <object> fallback model. To this end, I would like to look to the W3C WAI groups for guidance on this issue. To help me understand how <canvas> could be made more accessible, I would like to work from a concrete example: http://www.whatwg.org/issues/data.html This page uses <canvas> to generate a graph. Could I ask for advice on what the best possible way to make this page universally accessible would be? I would like to maintain the same visual presentation, but would like to make this page accessible to users of ATs. Could the WAI groups provide sample pages showing how, in an ideal world, with whatever APIs or accessibility hooks need to be made available, the page could be made accessible, while still maintaining its current dynamic generation and visual presentation? My goal here is to determine what the best APIs and other technical solutions would be to provide good accessibility as automatically as possible for people using <canvas>. I hope the combined accessibility expertise of the WAI groups will be able to design a solution for this that we can use in HTML5. I am at a loss personally as to how to do this. Any help would be greatly appreciated on this issue. Cheers, -- Ian Hickson
