Abstract
Control circuitry for a touch panel includes a touch panel interface, a memory including object classification logic, and a controller in communication with the memory and the touch panel interface. The controller is operable, when the object classification logic is executed, to perform selected processing of the touch panel heat map, including: classifying a touch as a hover touch, finger touch, or stylus touch; rejecting palm or other large object touches; rejecting knuckle touches; rejecting grip touches; and other processing.
