Abstract
Systems and methods for creating a finger keypad using the twelve finger segments of the human hand as a 12-key keypad are presented. In one embodiment, the finger segments are each associated with respective successive keys of a 12-key keypad, and a sensor device worn on the thumb or the wrist detects the thumb of the hand tapping on a selected finger segment and produces an output signal which varies based on which finger segment is tapped. A processor associated with the sensor device converts the output signals to corresponding 12-key values, and the 12-key values are converted to corresponding alpha-numeric values.
