Abstract:
Positioning a handle in a head mounted display system, and a head mounted display system. A wireless radio frequency master device is used on a head mounted device in the head mounted display system to perform operations of pairing with a wireless radio frequency slave device of a first handle and a wireless radio frequency slave device of a second handle. An electromagnetic wave receiver is used to receive electromagnetic waves emitted by an electromagnetic wave emitter of the first handle and an electromagnetic wave emitter of the second handle and generate an induced electromotive force. And, calculating position and posture information corresponding to the first handle and information of position and posture corresponding to the second handle respectively, wherein the position and posture information includes position translation information and direction rotation information when the wearer wears the first handle or the second handle.
