The optacon's retina has between 100 and 144 pixels. I read of a tiny camera which goes with the Ipaq which has over a million pixels in its small sensor. The Ipaq forms the basis for the PacMate and the Maestro PDAs. Does this technology not hold potential for a future optacon device? Scanners can also connect to Ipaqs, so a work station is indeed possible. The Optacon II's display has successfully been driven by a host, computerized device. The ongoing bottle neck is the display. Someone here will build me a replica of an optacon display so that it can be shown to some industry friends in India in January. A weak thread, perhaps? A slap against creeping obsolescence? An attack against overwhelming odds? Has Oleg's tactile display for the P2RD changed in any way?
