Some of you may find the below extensions interesting. -----Original Message----- From: BlindMath <[email protected]> On Behalf Of Neil Soiffer via BlindMath Sent: Thursday, May 26, 2022 11:07 AM To: Blind Math list for those interested in mathematics <[email protected]> Cc: Neil Soiffer <[email protected]> Subject: [BlindMath] Extension for improving math reading experience on Wikipedia
I'm happy to announce a FireFox extension <https://addons.mozilla.org/en-US/firefox/addon/accessible-wikipedia-math/>a nd a Chrome Extension <https://chrome.google.com/webstore/detail/accessible-wikipedia-math/gmkgdfm lbkhkchkocpnpfadkcmjnmpkj> for improving the math reading experience on Wikipedia pages. >From the extension's overview: Increases accessibility of math in Wikipedia pages by reverse engineering inline representations Wikipedia makes math accessible by hiding MathML next to the image it produces. Assistive Technology (AT) can then convert the MathML to speech or braille. This extension extends that trick to inline math by converting the "HTML math" in the page into MathML and inserting hidden MathML back into the document. The original output is hidden from AT by marking it with aria-hidden="true". Thus, the sighted user sees the original expression and the AT only sees the MathML. The improvement this extension makes varies with the page and the language. In the English pages, it makes a significant improvement: almost all but a few percent of the mathematical expressions are now accessible with this extension. The same is true to a somewhat lesser extent for the French pages. Most German, Asian, and Arabic pages appear to use embedded MathML and so the extension probably won't help for those languages because they are already accessible. If in doubt, try it out. This extension helps for displayed math also (mainly English pages). Many Wikipedia pages place larger math expressions on their own line inside of a list tag, probably for presentation reasons. However, this causes screen readers to say "list with one item" ... "out of list" for each piece of display math. This extension adds role="presentation" so that AT does not see the math as being a list and just reads the math. The display of the math is unaffected. The extension is only active on wikipedia.org pages. It should work with any AT that reads math in MathML. This includes JAWS, NVDA, VoiceOver, and Orca. No user data is collected by this extension. =========== Note: this is an update with several bug fixes of an experimental Firefox extension my son, a friend of his, and I released 6 years ago. I finally figured out how to make it work in Chrome. If there is enough interest, I can work with some to get a Safari version working -- I don't have a mac so I can't test anything. I hope some people find the extensions helpful, Neil Soiffer _______________________________________________ BlindMath mailing list [email protected] http://nfbnet.org/mailman/listinfo/blindmath_nfbnet.org To unsubscribe, change your list options or get your account info for BlindMath: http://nfbnet.org/mailman/options/blindmath_nfbnet.org/pranav.lal%40gmail.co m BlindMath Gems can be found at <http://www.blindscience.org/blindmath-gems-home> -- Disclaimer: 1.
