Abstract
A system and method for capacitive sensing comprises driving a first sensor electrode of a plurality of sensor electrodes with a first sensing signal to acquire a first resulting signal with the first sensor electrode during a period and driving a second sensor electrode of the plurality of sensor electrodes with the first sensing signal to acquire a second resulting signal with the second sensor electrode during the period. Further, a third sensor electrode of the plurality of sensor electrodes is driven with a reference signal during the period. Rotational information for an input object is determined at least partially based on the first resulting signal and the second resulting signal.
