1. A wearable electronic device, comprising:
a body;
a cover glass coupled to the body;
a plate coupled to the body, the plate configured to be positioned adjacent to a portion of a user when the wearable electronic device is worn;
a first sensor, coupled to the cover glass, that produces a first signal in response to a first force exerted on the cover glass;
a second sensor, coupled to the plate, that produces a second signal in response to a second force exerted between the portion of the user and the plate; and
a processing unit, communicably coupled to the first and second sensors, that is configured to adjust the first signal using the second signal.
