Abstract:
1. An apparatus, comprising: a conductor pattern including a plurality of first conductors disposed in a first direction and a plurality of second conductors disposed in a second direction different from the first direction; a first circuit for detecting first response signals produced by each of the plurality of first conductors to identify a first identified conductor of the plurality of first conductors; a second circuit for detecting second response signals produced by each of the plurality of second conductors to identify a second identified conductor of the plurality of second conductors, an intersection between the first identified conductor and the second identified conductor corresponding to a possible location of a user's interaction with the conductor pattern; and a signal processing circuit for receiving a select response signal from the second identified conductor produced in response to a select input signal applied to the first identified conductor, the select input signal being applied to the first identified conductor after the possible location is identified, the select response signal being used to determine whether the possible location is an actual location of the user's interaction with the conductor pattern.
