Abstract

The invention discloses a head-mounted display device, a handle and a positioning and tracking method thereof. The method includes: controlling an electromagnetic wave transmitter in the head-mounted display device to generate and emit electromagnetic waves; receiving an electromagnetic wave receiver in the handle to induce a corresponding induced electromotive force, And determine the relative position and direction information of the electromagnetic wave receiver and the electromagnetic wave transmitter according to the induced electromotive force and then send the relative position and direction information; according to the received relative position and direction information, determine the position of the handle in space. The embodiment of the present invention adopts the electromagnetic positioning technology, which avoids the influence of obstructions, ensures the positioning accuracy and facilitates the free movement of the user during operation.
