Long, long ago, I wrote a graphing program (MS-DOS) that was used in a
number of schools. I received a letter from a teacher at a school for
the blind explaining that they were using my program with a special
"screen" in which each monochrome pixel was represented by a raised pin,
like Braille. The students could then feel the graph. (Her request was
a way to turn off all the labeling and extra information on the screen
which made it more difficult to feel.)

That was almost 20 years ago, so I'm sure they have even better
technology today. Many states have state schools for the blind. Try
contacting their math dept to see what they are doing.

When one of my colleagues taught physics to a blind student, he rigged
up a beeper to a mercury switch mounted on the balance scale for labs.

All the best,
