A method of monitoring a subject includes detecting subject head motion information via a microelectromechanical systems sensor associated with an earpiece worn by the subject, processing, via a processor associated with the earpiece, the head motion information to determine subject head displacement relative to an origin and to determine if the subject has fallen down and/or is not moving, and transmitting the processed head motion information to a remote device. The method further includes communicating corrective action to the subject from the remote device and/or communicating corrective action for the subject from the remote device to a third party. The earpiece may include an audio headset, a hearing aid, or an earpiece fitting.

A wearable monitoring device configured to be attached to a subject includes at least one physiological sensor configured to identify the subject and to detect and/or measure physiological information from the subject, at least one motion sensor, at least one battery, digital memory storage, at least one processor, and at least one transceiver. The at least one transmitter communicates sensor data from the at least one physiological sensor and the at least one motion sensor with at least one remote device and receives targeted advertisement information from the at least one remote device. The targeted advertisement information is generated by processing the sensor data from the at least one physiological sensor and the at least one motion sensor.
