Abstract
A data input method and device is provided that allows a user to input data to a computer by means of bending his/her five band digits in a specified manner representing a keyboard character intended for input to the computer system. The bending of the user's five hand digits will then cause wrist muscle movements, which can be then sensed by a piezoelectric element in the data input device. In response, the piezoelectric element generates a corresponding electrical signal, which is then converted into binary form and transmitted via cable or wireless link to the computer system. Inside the computer system, the CPU searches through a predefined character-mapping table to find the character corresponding to the received signal from the data input device.
