1. A tracking system, comprising:
- a head-mounted display (HMD) worn on a head of a user and configured to virtualize a body movement of the user in a virtual environment; and
a plurality of sensors worn on feet of the user configured to determine body information of the user according to the body movement of the user, and transmit the determined body information to the HMD, each of the plurality of sensors being connected to the HMD via a first connection, the plurality of sensors being directly connected to each other via a second connection, a plurality of mutual relationships between each two of the plurality of sensors and between each of the plurality of sensors and the HMD being acquainted, each of the plurality of sensors comprising an inertial measurement unit to simulate a coordinate, each of the plurality of sensors sharing the coordinate of each of the plurality of sensors to each other via the second connection and to the HMD via the first connection;
wherein the HMD virtualizes the body movement of the user according to the determined body information;
wherein the body information is related to the plurality of mutual relationships between the each two of the plurality of sensors and between the each of the plurality of sensors and the HMD;
wherein one of plurality of sensors calibrates a relative distance and a relative location between the one and another of the plurality of sensors of the plurality of mutual relationships according to the shared coordinates via the second connection and the shared coordinates via the first connection, and the relative location and the relative distance between two of the plurality of sensors are acquainted by one of the plurality of sensors.
