Abstract:
1. A touch sensing system, comprising: a sensing device to sense at least one touch on a single layer sensor surface comprising a plurality of conductive strips disposed along one direction; and a processing device coupled to the sensing device to determine a horizontal position and a vertical position of the at least one touch by processing currents generated in response to the at least one touch, the currents simultaneously flowing in opposite directions away from the at least one touch through at least one of the plurality of conductive strips, wherein the processing device is configured to measure a first current through a first end of the at least one of the plurality of conductive strips and measure a second current through a second end of the at least one of the plurality of conductive strips, wherein the currents discharge a capacitor formed between the each one of the at least one touch and the single layer sensor surface.
