Computerized Braille ...invented by Roland Galarneau in 1972

I can prove that I and two associates invented this in 1960. I've got the certificate for the award of the "Louis DeFlorez prize" of $500 (split 3 ways) for this "invention." The other two guys in the team both used this invention as the subject for their MS theses, and formed a company to produce it no later than about 1968 – in the US.

(Of course it depends on what your really mean by Computerized Braille. It's best to be a bit vague in discussions of this kind.
