The Thumbscript, alphabet is based on the world¹s most common input device, the telephone keypad. The unique idea behind the technology is seeing the keypad, not as a series of numbers, but as a simple drawing slate. Users "draw" letters on the 9 buttons of the keypad or on a 9 dot target. With a
visual resemblance to standard letters, Thumbscript is remarkably easy to learn and natural to use. Extending the visual metaphor, the system gives direct access to everything on the standard keyboard without mode shifting or menu choices.
