Abstract:
A method includes obtaining various resistance measurements of a sensor electrode in an input device, where the resistance measurements correspond to electrical resistance values across the sensor electrode. The method further includes obtaining a capacitive response using various sensor electrodes in the input device, where the capacitive response corresponds to changes in capacitance in response to an input object being located in a sensing region. The method further includes determining an adjusted capacitive response using the resistance measurements and the capacitive response. The method further includes determining, using the adjusted capacitive response, object information regarding the input object in the sensing region.
