Abstract:
A key pad device provides the same function as a keyboard or keypad with a mistake proof design that allows one hand use and only requires three fingers. Each of the primary two fingers has nine pressure points, or keys, whose location is accessible by moving left to right, up and down, forward and back, side to side, and center. A thumb toggle can operate in one of three positions—up, down or not toggled.
