Hey listers, Thanks for all your comments. Here are a few more remarks. First of : I proposed to hit "Enter" after each Braille character so to signal to the device that this character was complete. An alternative would be to have two Braille cells and to alternate between them. I don't know which would be ergonomically and timewise more efficient. To Tom : I am glad to hear you are still working on these PDAs. You had sent me a msg last December I believe where you told me about that work at Smith Kettlewell. Is it any further? I know you said I shouldn't hold my breath but could you give me even a rough estimation of when this product will be ready? Can I be a Beta-tester? I agree that it should be easier and cheeper to use and modify off-the-shelve devices rather than build one from scratch; But I don't understand why the device I imagined would require such a powerful processor. Afterall, devices like the RoadRunner, the ErgoBraille, the Memona Plus can already talk. Of course a PDA with GPS, the Internet, Word Processors, and spreadsheet programs would be even better, especially for 200 bucks. But the device I envisioned was much simpler and I hoped much easier to build and put on the market... ;-) Otherwise, I was very please to see that at least 4 or 5 different people told me they liked my idea. I think I will try to suggest it further to developpers. I feared that people were not interested anymore in inputing in Braille nowadays. I'll let you all know if anything comes out of this.
