Abstract
A touch-sensing apparatus may include a first controller configured to measure a first set of capacitance values from a first area of a touch-sensing surface and a second controller coupled with the first controller, where the second controller is configured to receive the first set of capacitance values from the first controller, and calculate a first position of a contact at the touch-sensing surface based on the first set of capacitance values and a second set of capacitance values measured from a second area of the touch-sensing surface adjacent to the first area of the touch-sensing surface.
