Patent Images
1. A finger recognition method for use in an electronic device, comprising:
- providing a database, wherein the database records a shape corresponding to at least one finger;
detecting a contact corresponding to an input tool via a touch-sensitive device;
obtaining a shape corresponding to the input tool according to the contact;
determining whether the shape corresponding to the input tool conforms to the shape corresponding to the at least one finger recorded in the database; and
when the shape corresponding to the input tool conforms to the shape corresponding to the at least one finger recorded in the database, determining the input tool to be a finger.

Abstract
Finger recognition methods and systems for use in an electronic device are provided. First, a contact corresponding to an input tool is detected via a touch-sensitive device, and a shape corresponding to the input tool is obtained according to the contact. It is determined whether the shape corresponding to the input tool conforms to a shape corresponding to the at least one finger recorded in a database. If so, the input tool is determined to be a finger.
