[Blindmath] Math Computer Program

Sun Mar 2 19:21:54 UTC 2014

Hi Tami, yes it is easy to put in braille input for LEAN Braille, which is
more or less a braille equivalent of the LEAN notation.  If there are people
who will use it, I could do that easily.

Composing in Nemeth or other official braille language is infinitely more
difficult, partly because all math braille languages have ambiguities (which
could be accounted for in various ways - in fact easily for Nemeth), but
more particularly, all are context-dependent, and that is a real killer.
Truthfully I don't know how to incorporate Nemeth equation composition, and
other braille math languages are even more difficult.  It is something I'm
trying to understand better and might someday be able to do.  But not
imminently unfortunately.

Be well all.
John

John,

Great work, and congratulations on your progress!

You say presently one can't compose the equation using braille. Is this a
feature that will be added in the future? I'm asking more out of curiosity
than anything. By the time I do get back to taking math classes, LEAN Math
will be one of the exciting new programs I plan to explore! Even if I have
to use nasty old MS Word. /grin/

I like the idea of being able to type in braille while I'm working in
braille, especially on complex tasks. It's not as big a deal for me to
switch back and forth as it was at first, but I still like to think in dots
when I'm using dots, if that makes sense.

Keep up the good work!

Tami
