Abstract
A tracking system includes an attachable device and a tracking device. The attachable device is removably mounted on a head mounted display device. The attachable device includes an optical emitting module for emitting optical radiation. The tracking device is communicated with the attachable device. The tracking device includes an optical sensor for receiving the optical radiation. The tracking device calculates spatial coordinates of the attachable device relative to the tracking device according to the optical radiation sensed by the optical sensor. The tracking device transmits the spatial coordinates to the attachable device or the head mounted display device.
