Claim:
1. A capacitive input device comprising: a plurality of sensing electrodes configured to sense objects in a sensing region; a conductor; a shield layer comprising at least one shield electrode, the at least one shield electrode disposed between the plurality of sensing electrodes and the conductor; a processing system coupled to the plurality of sensing electrodes and the at least one shield electrode, the processing system configured to: operate in a first mode, wherein when operating in the first mode the processing system is configured to electrically drive the at least one shield electrode and to determine position information for objects in the sensing region using the plurality of sensing electrodes; and operate in a second mode, wherein when operating in the second mode the processing system is configured to electrically float the at least one shield electrode and to determine force information for objects in the sensing region using the plurality of sensing electrodes.
