Is there any Mathematica functionality enabling its use for the blind?

I taught a blind student at our Uni a 1st year Maths module. We used his MacBook Air and he had a hardware device that rendered mac output as braille. We found that the key to communicating mathematics was a simplified form of LaTeX - which the student picked up very quickly. This, combined with Mathematica's LaTeX facility proved very successful.

My friend is using Mathematicа for quite a long time with the Jaws program. He is physicist and visually impaired. He uses it for scientific work. If there is still interest, he can share some tricks with the program.
