To be a bit more specific, MathJax can output SVG when it runs in the user
agent (e.g., a web browser or eReader). However, as Rich mentions, this
process of converting MathML or other math input formats to browser
renderable formats in the user agent does require runtime processing and
would not be as performant as converting the MathML to accessible/described
SVG prior to EPUB packaging and/or transmission to the user agent.

      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.
