Palm Detection Using Multiple Types of Capacitance Measurements
18 May 23
A touch sensor may include a substrate; a first set of electrodes and a second set of electrodes that are in communication with a capacitance controller; memory in communication with the capacitance controller where the memory includes programmed instructions that, when executed, cause the capacitance controller to take a first capacitance measurement using a first capacitance measurement technique capable of detecting an object within a first range; take a second capacitance measurement using a second capacitance measurement technique capable of detecting the object within a second range, wherein the second range is larger than the first range; and determine, based at least in part on both the first capacitance measurement and the second capacitance measurement, that an object is resting proximate the touch sensor.
