Comment I did some work on this a while back. (Score 2) 89
A couple years ago when I was working at chumby I worked with Rich Rarey at NPR Labs and wrote the code to get the braille device talking to the display device you see at 6:35 (which is an Insignia Infocast, Best Buy's OEM version of the Chumby 8) and also wrote an ActionScript extension module in C++ to allow them to write to the braille printing device and get input from it (via a custom USB protocol) within a Flash/ActionScript3 app, which is what their closed caption software was written in.
Pretty cool project -- glad to see they are still working on this and extending it.
