Abstract
A processing system for an input device includes a sensor module coupled to sensor electrodes. The sensor module includes sensor circuitry and configured to acquire first capacitive measurements when the input device is in a first state, and acquire second capacitive measurements when the input device is in a second state. The second state has an increased ground as compared to the first state. The processing system further includes a determination module configured to determine positional information for an input object based on the first capacitive measurements and the second capacitive measurements.
