Word-level Unistroke Soft Keyboards

A word-level unistroke keyboard is a soft keyboard allowing a user to go from any key to any other key without lifting the pen or entering unwanted keys. We've created javascript demos of two such keyboards, a circular one, and one consisting of two vertical columns. We've published a paper about Cirrin as well. The system is actually part of a suite of input and output tools (inputlets and outputlets), in use in a DigitalDesk-like environment as part of the Pendragon project. These include a foot mouse, a keyboard, a software mouse, soft-key buttons, and several circular word-level keyboards with complementary character sets. With this combination, our user often finds herself doing four-limbed input!
