US 2011/0084937 A1 · Method and device for analyzing positions

Abstract

A method and device for analyzing positions are disclosed. In sensing information, at least one position is determined according to a first characteristic of a touch related sensing information. The sensing information also has a touch related sensing information with a second characteristic, which is opposite to the first characteristic. The touch related sensing information with the second characteristic is neglected or filtered. In addition, another method and device for analyzing positions are disclosed. An AC signal is provided through a pen, and a first characteristic of a touch related sensing information corresponding to a finger is opposite to the second characteristic of the touch related sensing information corresponding to the pen. The first characteristic and the second characteristic can be used to distinguish the touch of the finger from the touch of the pen or for palm rejection.

Dependent claims

A method for analyzing positions, comprising:

obtaining a touch sensitive information from a plurality of sensors corresponding to at least one first external object touching or approaching a signal source, wherein the at least one first external object electrically coupled with at least one second external object, and the touch sensitive information corresponds to signals of these sensors mutual-capacitively coupled to the signal source, the at least one first external object and the at least one second external object;
determining a characteristic in the touch sensitive information corresponding to the at least one first external object;
and
analyzing a position corresponding to the at least one first external object only at a portion in the touch sensitive information that matches the characteristic.
