There is an enormous range of products that produce braile and tactile images. Least interesting of these are printers that print out the image embossed, or describe it with braile, or print text. Some of these are also equiped with speach synthesisers and microphones. I assume these would be very useful to the very low percentage of people who actually read braile. The most interesting product i cam across was the "thermo pen" which has a heated tip that when moved slowly across paper creates tactile lines words or symbols. Braile labelers, keyboards, watches, games and learning tools are also available.
