[BlindMath] Areas still to work on?

What you type in would appear in the 2d Braille display as Braille math code.  At least, in "math mode."  It would take too many dots to get print letters up, though, some symbols, you could draw, if you wanted, like radical sign, which is very different in form in Braille, and you might need to just draw that.  Possibly, the computer could have some OCR in it to recognize the symbols you are drawing, like fraction lines, and such and put that in the final result.

Just curious: if the device is not for Braille, then how would the typed characters appear? Surely not in print :).

You'd take this "pen" type device, and as you run it over the pad, Braille dots would pop up, and the computer would register what you're doing.  You could type in letters on the computer, letters and numbers and symbols, where you want, and they'd appear under the pen, too.  The back end of the pen would send a different signal, to erase things.  You could sketch just about anything that way, actually.  The tech exists, though it's not something most people could afford, except for the government, student loans, etc.
