Abstract
In one embodiment, a method includes in an inductive-sensing mode, by a controller, applying an alternating-current (AC) signal on a first electrode of a capacitive touch sensor. The capacitive touch sensor is configured to operate in the inductive-sensing mode and a capacitive-sensing mode. The method also includes sensing a signal indicative of a magnetic field on the first electrode. The signal is due at least in part to a magnetic field generated by the object and the magnetic field is generated at least in part in response to the AC signal applied on the first electrode. The method also includes determining a position of the object generating the magnetic field based on the signal indicative of the magnetic field.
