Patent Images
1. A method for detecting one or more objects, comprising:
- receiving one or more induction signals caused by at least one object along one or more directions;
comparing each received induction signal with a reference to detect at least one upward trend and/or at least one downward trend in the induction signal; and
determining the number of objects based on the number of upward trends and/or downward trends in each received induction signal.

Abstract
A method for detecting one or more objects is disclosed. In one embodiment, the method comprises the steps of: receiving one or more induction signals caused by at least one object along one or more directions; comparing each received induction signal with a reference to detect at least one upward trend and/or at least one downward trend in the induction signal; and determining the number of objects based on the number of upward trend and/or downward trend in each received induction signal. A device for detecting one or more objects on a touch device is also disclosed.
