Use of comparative sensor data to determine orientation of head relative to body

摘要

Methods and systems are described that involve a head-mountable display (HMD) or an associated device determining the orientation of a person's head relative to their body. To do so, example methods and systems may compare sensor data from the HMD to corresponding sensor data from a tracking device that is expected to move in a manner that follows the wearer's body, such a mobile phone that is located in the HMD wearer's pocket.
