1. 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 the sensors operatively coupling with 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 at least one position corresponding to the at least one first external object only at the portions in the touch sensitive information that matches the characteristic.
