Actually the only problem with a stylus is no real tactile feedback and your right, characters not normally used in braille. THings like ctrl alt etc. could probably be implemented easily enough. Touch screens would work, but you'l need that template in order to know where to put your fingers. I imagine even a small standard keyboard would be possible, but then there would have to be provisions for screen review keys. Still not impossible. Geez its been a while since I used a braille writer. Always have used a slate and stylus. In any case the braille writer keyboard would certainly save space and although I havent' played with the Braille-N-Speak much, I think they've nailed down many commands. An idea along those lines would be possible. Lots of thoughts. I wonder if there would be a way to contact someone in the enginering and manufacturing side of the house for comments as well. They aren't familiar perhaps with the needs of those who would use these devics, but they might have some thoughts on how to implement it with the existing systems. I know a gent who works at Sony for example although he is in the cd pressing business. Its possible he might have a contact. Just a thought. It would be something to see this go from an idea on a reflector to reallity. Would be a first.
