Abstract
Touch sensor methods, devices and systems are disclosed. One embodiment of the present invention pertains to a touch sensing system comprising a sensing device for sensing one or more touches on a sensor surface made of multiple conductive strips in one direction and a dual processing device for determining a horizontal position and a vertical position of each touch by processing currents generated in response to the touch, where the currents charge and discharge a capacitor formed between the touch and the sensor surface.
