[BlindMath] Help with NVDA and MathML

Mon Jul 16 18:13:44 UTC 2018

Sorry that Portuguese did not find its way into MathPlayer. I do see that the MathJax localization does include Portuguese, so if the page in question uses MathJax to serve the math, then you might be able to get it to work. There's a way to turn on the accessibility extension in MathJax, but you may need to check the documentation to figure ouit how to do that. Perhaps here: http://docs.mathjax.org/en/latest/misc/accessibility-features.html

Thanks Steve

I installed Mathplayer, now i can read some formulas on Internet Explorer, but for some reason i still cant read on Mozzila.

But now i realize that MathPlayer dont have Portuguese on his languages, is there anyway of reading formulas with NVDA without using MathPlayer.

If you are finding that NVDA is not reading the math expressions, be sure that you have MathPlayer installed on your PC. Here's the direct download link: https://www.dessci.com/en/dl/MathPlayerSetup.exe<https://urldefense.proofpoint.com/v2/url?u=https-3A__www.dessci.com_en_dl_MathPlayerSetup.exe&d=DwMFaQ&c=OAG1LQNACBDguGvBeNj18Swhr9TMTjS-x4O_KuapPgY&r=67olWPWhVEsI50vpRdydglG2RHA1T81UHrTuRDeUqW4&m=csOtbkkIRpVXtwudVasf6FC5jGDPy0Aw95kmDwLt-9Q&s=BJzi4fGs8TS1mMvwQtBBJSpIfwyZp1xo7uUYqi2NgWA&e=>

Hi everyone!

I’m Alberto, and I work with Math texts in a VEL (Virtual Environment
Learning) called
Canvas and need NVDA to read formulas in this platform. However, Canvas
sees LaTex as
an image which NVDA cannot read. So far I´ve described all formulas like
text from image
attributes, so NVDA can read it. However, I need to find another way of
doing this reading
but run into the issues as follows.

1) Using of MathML
I’ve looked in the old threads and, as far as I know, NVDA can read pages
that use
MathML. In YouTube, I’ve found a video that shows the reading being made:

https://urldefense.proofpoint.com/v2/url?u=https-3A__www.youtube.com_watch-3Fv-3Dckx-2Djl99Iic&d=DwIGaQ&c=OAG1LQNACBDguGvBeNj18Swhr9TMTjS-x4O_KuapPgY&r=67olWPWhVEsI50vpRdydglG2RHA1T81UHrTuRDeUqW4&m=IiJF--XJbPEma-eRSjBibl3VTs1ouk-pGYq9rvSjUME&s=bn6ozpu7vH2X5PjrOhSY_QzlzgaBGdR0Q4JVM1NtPr4&e=

I’ve installed NVDA to test this reading, but I couldn’t read it properly.
Therefore, I
tried to read this page that is using MathML and I also failed:

https://urldefense.proofpoint.com/v2/url?u=https-3A__www.freedomscientific.com_content_html_jawshq_MathML-2DSamples.html&d=DwIGaQ&c=OAG1LQNACBDguGvBeNj18Swhr9TMTjS-x4O_KuapPgY&r=67olWPWhVEsI50vpRdydglG2RHA1T81UHrTuRDeUqW4&m=IiJF--XJbPEma-eRSjBibl3VTs1ouk-pGYq9rvSjUME&s=3ruHgaNQTW6aZALzqbbCNXqKnwk-rldmu2dg_CWni7I&e=

I use Firefox and the page loads correctly but NVDA doesn’t recognize the
formulas
and reads them as a normal text. In the third topic, for example, it can’t
recognize
fractions. It reads them, again, as a text.
Maybe I need some sort of NVDA’s plugin to do this reading?

2) Describing formulas
Does any standard exist to describe formulas? I have difficulties to
describe limits,
matrixes and equations. Now, we’re describing formulas and making tests
with a
blind person to check if he can read, but we really need a describing
template.

Does
anyone know if any type of template exists for it?

Another and last thing: is there any page with examples of accessible math
texts? If
they exist, do you know where I can consult them?
