Finger-identifying keyboard
First Claim
1. A finger-identifying keyboard, comprising:
- a plurality of keys;
a plurality of sensors, each of which is uniquely associated with a different finger;
a coding synthesizer used to simultaneously identify the keys and the fingers used to press the keys, to synthesize the coding, and generate the resultant input coding signal.

Abstract
The present invention provides a finger-identifying keyboard, comprising a plurality of keys; a plurality of sensors, each of which uniquely represents and identifies a different finger; a coding synthesizer used to identify simultaneously the keys and the fingers used to press the keys, to synthesize the coding and to generate the resultant input coding signal. The invention can effectively reduce the number of keys on the keyboard, thereby achieving the goal of reducing the size of the keyboard so as to be adapted to the requirements of various handheld devices. Even though the size of the keyboard is reduced, the size of the finger keys can remain the same size to facilitate typing.
