[Blindmath] Making Mathtype documents in Word accessible

Sun Dec 4 07:34:18 UTC 2011

We are working on navigation as part of a grant that we received to improve
math accessibility.  My plans for braille are that as one navigates the
math (not the words nor the braille), that MathPlayer will generate the
appropriate speech and also the appropriate math braille code that
corresponds to it.  Eg, if you navigate into the numerator of a fraction
and the numerator is spoken, the math braille code corresponding to that
numerator will be what is available for the screen reader to put on the
braille display.

There are lots of details to be worked out though.  Eg, navigating into the
numerator will likely generate a speech string like "In numerator, x
squared plus y squared".  I don't know what, if anything, we will generate
for braille that corresponds to "in numerator".  Once we get to the point
of detailed design, I'll be asking the list for suggestions as to what
should happen.
