Not a .pdf, no. I think there may've been research on Braille --- but
isn't there a special notation / extension for math done in Braille
Some discussion of this here:
But it's 12 years old? Here's a company doing something along these
lines: http://www.duxburysystems.com (Windows only apparently).
This sort of thing may get better for .pdfs once the Stixfonts
( http://www.stixfonts.org/ ) are available, but even then will
probably need improvements in screen reader support ('cause I'm not
convinced that they'll read out a superscripted ``2'' as ``squared'').
As a test on that, try a .pdf of $a^2 + b^2 = c^2$ --- someone needs
to teach these screen reader folks that the Pythagorean theorem is
_not_ ``a2 plus b2 equals c2''.
Really though, (La)TeX source is quite readable and concise and a
reasonably linear representation, so should be suitable for use by a
screen reader if it'll accept plain text files.
