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.
