1. A wearable electronic device, comprising:
a body;
a cover 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, that produces a first signal in response to movement of the cover;
a second sensor, coupled to the plate, that produces a second signal in response to movement of the plate; and
