    Abstract: A tracking method for tracking a head-mounted device includes following steps. First pose data of the head-mounted device is tracked in an inside-out coordinate system. Second pose data of the head-mounted device is tracked in an outside-in coordinate system. A transformation relationship between the inside-out coordinate system and the outside-in coordinate system is calculated according to the first pose data and the second pose data. The first pose data in the inside-out coordinate system is transformed into third pose data in the outside-in coordinate system according to the transformation relationship. In response to that the second pose data is currently available, the second pose data is utilized to determine a device pose of the head-mounted device. In response to that the second pose data is currently unavailable, the third pose data is utilized to determine the device pose of the head-mounted device.
