Abstract
A wearable device for detecting a user state is disclosed. The wearable device includes one or more of an accelerometer for measuring an acceleration of a user, a magnetometer for measuring a magnetic field associated with the user's change of orientation, and a gyroscope. The wearable device also includes one or more microphones for receiving audio. The wearable device may determine whether the orientation of the wearable device has changed and may designate or re-designate microphones as primary or secondary microphones.
