MULTITOUCH - FingerWorks Compatible Computer Devices

Description extracted from Wikipedia:

FingerWorks was a gesture recognition company based in the United States, known mainly for its TouchStream multi-touch keyboard. Founded by John Elias and Wayne Westerman of the University of Delaware in 1998, it produced a line of multi-touch products including the iGesture Pad and the TouchStream keyboard, which were particularly helpful for people suffering from RSI and other medical conditions. The keyboards were immediately discontinued when the company's assets were acquired by Apple Inc. in early 2005.
