What is the Blissymbol Printer? It's a software program invented by a Canadian 12-year-old in the mid-1980s. Zimmerman's printer enables those with severe physical disabilities like cerebral palsy, to communicate. The user records their thoughts by touching symbols on a page or board through the use of a special touch pad, the printer then translates the symbols into a written language. Zimmerman's system started as a project for a school science fair, but ended up competing and winning a silver medal in a nationwide contest, as well as gaining her the YTV Television Youth Achievement Award.
