1. An input device comprising:
a chassis having an interactive region comprising a conductive surface; an input surface configured to deflect relative to the conductive surface in response to applied force, the input surface comprising a capacitive sensing layer comprising a plurality of transmitter electrodes and a plurality of receiver electrodes, the capacitive sensing layer has a first region and a second region, wherein the capacitive sensing layer has an electrical interaction with the conductive surface, and wherein the conductive surface is grounded; and a processing system communicatively coupled to the input surface and configured to:
transmit a transmitter signal using the plurality of transmitter electrodes,receive, using the plurality of receiver electrodes, a resulting signal comprising effects of the transmitter signal and the electrical interaction between the conductive surface and the capacitive sensing layer,determine, from the resulting signal, force information attributable to a relative magnitude of deflection, toward the conductive surface, of the first region as compared to deflection, toward the conductive surface, of the second region in response to an applied force, anddisambiguate the first region and the second region based on the relative magnitude of deflection in the force information. |
