Dear Kevin, I am responsible for the Laboratory for research and
experimentation with novel assistive technologies for STEM "S.Polin", at
the Department of Mathematics of the University of Torino, Italy. Our
website is


In 2018 we have developed the LaTeX package Axessibility, which enables a
user of screen reader/braille display to access the LaTeX code of a pdf
(coming from LaTeX). We also have dictionaries for Jaws and NVDA.

In case you are interested, you may have a look at the web page


Please feel free to contact us through this email for any question/comment.
We are eager to obtain feedbacks from users like you.
