Abstract
The present disclosure is directed to a system and method of determining a movement of a user's head with a ranging sensor. The ranging sensor transmits a ranging signal that is reflected off of a user's shoulder and received back at the ranging sensor. The received ranging signal can be used to determine distance between the user's head and the user's shoulder or to determine the reflectivity of the user's shoulder. With the distance or the reflectivity, a processor can be used to determine movement of the user's head. Furthermore, a multiple zone ranging sensor or multiple ranging sensors can be used to detect the user's shoulder in different spatial zones.
