The embodiments of the disclosure provide a method for tracking trackers and a host. The method includes: obtaining a first relative pose between a first tracker and a second tracker; in response to determining that the first relative pose is stable, determining whether a first pose of the first tracker is trackable; and in response to determining that the first pose of the first tracker is untrackable, determining the first pose of the first tracker based on a second pose of the second tracker and the first relative pose.
