Re: The AAP EPUB 3 Implementation Project

Hi Jean,

No. We can use ARIA for either HTML or SVG. SVG is just a better fit for
mobile devices and is a lot simpler. I have been discussing the SVG
approach with Gerardo and he has covered that topic in his post. MathJAX
currently renders MathML using JavaScript and HTML but it slower. SVG was
designed for drawing.

ARIA semantics, currently, are largely designed for widgets and landmarks.
We could use labelling to provided accessibility information to the content
either through <title> or <description>. We could also create a taxonomy
around the Math symbols that are drawn. I fact, we have discussed creating
other modules for ARIA (instead of one big monolithic spec.) to deal with
other taxonomies - charts, math, etc.. The tabindex support will be big for
Math rendered in SVG.

I will try to attend the webinar today. Thank you for the pointer to the
use cases.

Hi Richard – Welcome to the group!

I just saw your comments in my inbox, and as I’m getting ready to do a
mathml webinar tomorrow, you immediately got my attention…

You say that “A big issue will be getting open source MathML readers
(voice) and renders – preferably based on SVG as it is a good fit for
mobile.”

Do you mean that it would be better to have MathML that is rendered as SVG
than rendered natively in a browser because of the ARIA and tab index
support?

The DPUB has started to collect some MathML use cases here:
http://www.w3.org/dpub/IG/wiki/MathML_UC. We would definitely like to
identify and record additional use cases around MathML and Accessibility.
Please go ahead and send email to the group regarding any MathML use cases
you wish to add. I’ve been the “de facto” keeper of the MathML use cases
for the group to date. (yep. I volunteered. And sort of dragged Peter along
with me, since he’s the guy who provided the initial write-ups of the 3 use
cases we’ve documented to date…)

Here’s the link to register for the webinar we’re doing tomorrow if
anyone’s interested:

This was originally going to be a 2 person effort between Peter
Krautzberger of MathJax and myself, but we recently expanded our speaker
list by one to include Sanders Kleinfeld from O’Reilly who will be
presenting a case study about how O’Reilly built a toolchain API to deal
with the need to put math on different retail reading devices in addition
to mobile apps, the web, and in printed books.

Ivan,

This is a great. Going forward we will be able to expand on ePub's
accessibility capabilities. For example, SVG 2 now has ARIA and tabindex in
the spec. In the future we will be able to roll this support into books. A
big issue will be getting open source MathML readers (voice) and renders -
preferably based on SVG as it is a good fit for mobile. Access to digital
math by the blind and those with attention deficit would benefit from
having this capability. In fact we recently did a study for the Department
of Education. The ability for students to have Math navigable through
highlighting and speech improved math comprehension by 10-15 percent across
the board.

Lots of good guidelines point on accessibility issues, for example
