[BlindMath] Support for MathML in browsers/screen readers

Hi Birker,

For a while, the Benetech DIAGRAM project was tracking this via a crowdsource testing effort, and the results are still available in their Math Support Finder at https://msf.mathmlcloud.org/

Like many crowdsource efforts, there was an initial flurry of folks doing testing, but after a while it falls off the radar. Nonetheless, it is probably still the best source for this information. There's also another effort by the DAISY Consortium to do much the same thing for EPUB reading systems, but they have only recently added tests for MathML, so not many systems have such information listed. You can find those tests results at http://epubtest.org/results

Generally speaking, NVDA works well when the MathPlayer add-on is installed, and either Firefox or Chrome is used. JAWS is not dependent on MathPlayer, but the browser coverage may be different. ChromeVox in the ChromeOS with Chrome and VoiceOver with Safari in the MacOS and iOS are all still working as far as I know.

Hope that helps,

--Steve Noble

Subject: [BlindMath] Support for MathML in browsers/screen readers


There has been a discussion about browser/screen reader support for
MathML content over on the WebAIM mailing list.
Can anybody give me the quick answer about MathML support? Which
browser/SR combinations are the best?
Does installing a browser add-on or some suchmake the experience better?
With assessments moving from paper to the web, we need to ensure
web-based math can be encoded in a way that is undersandable to a
screen reader user.
Ihave not been keeping up with math for some time now (I ambusy with
web and mobile aps accessibility) but my understanding was that MathML
support has been inadequate/inconsistent, but I definitely hope that
impression is inaccurate. :)Thanks
