Dear Anne:

I am sharing the same interest with you regarding accessibility of web and
other publications for people with cognitive or mental disabilities.
The Japanese Society for Rehabilitation of Persons with Disability is a
member of the DAISY Consortium (www.daisy.org) representing Japan, and has
been working on implementation of DAISY for blindness community in Japan and
developing countries.  In addition to our work for people with visual
impairements, we have been studying the needs of all other "print disabled"
people to adapt DAISY or physically accessible synchronized multimedia as a
technological solution.
We have started to develop DAISY version of "easy to read books" in
cooperation with dyslexia concerned organizations and parents organizations
of people with mental disabilities.  We also produce a trial version of SMIL
textbook of science for the second grade of junior highschool.
I believe that WAI should address the needs of people with cognitive or
mentally disability.  I see the SMIL applications like DAISY is most
promising and practical approach to make the web and all other XML
applications including Digital TV, eBook, WAP, I-mode, etc., accessible to
all at the moment.

Best

Hiroshi
