[Blindmath] Accessible display format for matrices

[Richard Baldwin]

Hi Pranav,

Thanks for the input. I understand how a spreadsheet can be used for doing
matrix computations. The main thing that I am looking for is the most
accessible display format. For example, MathML can be used to create
beautiful matrix equations in an HTML page. Beautiful, that is, for sighted
students. However, NVDA becomes silent when it encounters MathML in a web
page. I don't have a copy of Jaws, so I don't know how it reacts to MathML
in a web page.

Most normal equations can be handled in an accessible manner by writing
them on a single line using programming format. Matrix equations, on the
other hand typically require three or four lines. I wondering how to
configure those three or four lines in such a way that a blind student can
make sense of them.

Thanks,
Dick Baldwin
