1. A lineographic data input system for allowing a user to enter alphanumeric characters, numbers, and symbols into an electronic device, said lineographic input system comprising: a keypad bordered by a raised frame, said keypad consisting of 12 touch sensitive cells and a touch sensitive grid separating said cells, each of said cells and said grid adapted to generate an input signal when touched, whereby a user trace that touches a first one of said 12 touch sensitive cells and crosses over a portion of said grid to an adjacent second one of said 12 touch sensitive cells thereby generates a complete signal, said complete signal including signals corresponding to said first one of said cells, said second one of said cells, and said portion of the grid crossed; said keypad electrically connected to means for electronically processing said input signals from said keypad and corresponding said input signals with alphanumeric characters, numbers, and symbols; wherein each of the 26 letters of the alphabet correspond to a complete input signal formed by a single linear trace on said keypad, said linear trace touching only two adjacent cells and a portion of said grid; whereby data input may be entered into an electronic device by making short linear traces across the cells and grid thereby generating said input signals corresponding to alphanumeric characters, numbers, and symbols.
