Data input method and device for a computer system
First Claim
1. A data input method for use with a computer system for user data input to the computer system, comprising the steps of:
- (1) predefining a set of combinations of hand digit movements, each combination of hand digit movements representing a specific character, (2) predefining a character mapping table which maps each combination of hand digit movements predefined in said step (1) to a specific character, (3) sensing user'"'"'s wrist muscle movements due to the user'"'"'s hand digit movements representing a character intended for input to the computer system, and thereby producing a corresponding data signal;
(4) transmitting the data signal to the computer system; and
(5) searching through the character mapping table to find the character corresponding to the received data signal.

Abstract
A data input method and device is designed for use with a computer system, which allows the user to input computer data, such as keyboard characters including alphabetic letters, numbers, special marks, and control codes, into the computer system. The proposed data input method and device allows the user to input data to the computer system by means of bending his/her five hand 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, and then displays the retrieved character on the monitor screen, completing the input of one keyboard character to the computer system.
