Java-Powered Braille Slate Talker

A new device, the Braille Slate Talker, is introduced. An ordinary hand held device (a PDA) is used with a fixed layout plastic guide placed over the touch screen to allow Braille input. Contracted Braille is converted to text by a table-driven state machine. Programs are written in Java language to provide full hardware and software platform independence. Future network applications will use Sun's Jini technology.
