[BlindMath] Help with NVDA and MathML

[Noble,Stephen L.]

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

You can read more about MathPlayer on this page: https://www.dessci.com/en/products/mathplayer/download.htm


Hope that helps,

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?
