Last night I led a session on the history of braille production for the Bristol Braillists Group. They meet every couple of months to test and give feedback on the Canute, a low-cost braille e-book reader being developed by Bristol Braille Technology.
My talk covered devices for personal braille production, rather than duplication equipment. Devices like the Perkins Brailler, the Stainsby, various hand frames and modern electronic braille note takers with refreshable braille displays
