In one embodiment, a method comprises generating, by a control unit, a first drive signal and a second drive signal. The method further includes emitting, by a touch sensor, a first electric field that extends in a plurality of directions in response to reception of the first drive signal. The method also includes attenuating, by a conductive shield, a portion of the first electric field that extends from the touch sensor towards the conductive shield by generating a second electric field in response to reception of the second drive signal. |
