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 in space;
identifying two or more values of the induction signal in one or more directions in space;
comparing each of the two or more values with a reference;
determining at least one upward trend and/or at least one downward trend in space if one of the two or more values is greater than the reference and another one of the two or more values is no greater than the reference; and
determining the number of objects based on the number of upward trends and/or downward trends in space in each received induction signal;
wherein the reference is obtained by measuring, averaging and evaluating an induction caliber of induction lines in one or more directions.

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.

9. A method for detecting one or more objects on a touch device, comprising:
-
receiving one or more induction signals caused by at least one object along one or more directions in space on the touch panel of the touch device; identifying two or more values of the induction signal in one or more directions in space; comparing each of the two or more values with a reference; determining at least one upward trend and/or at least one downward trend in space if one of the two or more values is greater than the reference and another one of the two or more values is no greater than the reference; and determining the number of objects based on the number of upward trends and/or downward trends in space in each received induction signal; wherein the reference is obtained by measuring, averaging and evaluating an induction caliber of induction lines in one or more directions. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A device for detecting one or more objects on a touch device, comprising:
a detecting module, configured to detect one or more induction signals caused by at least one object along one or more directions in space on the touch panel of the touch device; and
a calculating module, configured to receive the induction signal, identify two or more values of the induction signal in space, comparing each of the two or more values with a reference, determining at least one upward trend and/or at least one downward trend in space if one of the two or more values is greater than the reference and another one of the two or more values is no greater than the reference, and determine the number of objects based on the number of upward trends and/or downward trend in each received induction signal;
wherein the reference is obtained by measuring, averaging and evaluating an induction caliber of induction lines in one or more directions.- View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
