1. A head-mounted display, comprising:
a display;
a first image capturing device, being configured to generate a plurality of first real-time images including a self-tracking device in a physical space; and
a processor, being electrically connected to the display and the first image capturing device, and being configured to perform operations comprising:
receiving a first self-tracking pose information from the self-tracking device, wherein the first self-tracking pose information is calculated by the self-tracking device, and the first self-tracking pose information corresponds to a hand holding pose information of a user;
generating a hand pose information based on the first real-time images, wherein the hand pose information is a six-degree-of-freedom information;
calculating a drift information of the hand pose information and the first self-tracking pose information;
calibrating the first self-tracking pose information based on the drift information; and
transmitting the drift information to the self-tracking device to make the self-tracking device calibrate a coordinate system of the self-tracking device based on the drift information.
