Abstract
The invention relates to a method of tracking the position of the bust of a user on the basis of a video image stream, said bus comprising the user's torso and head, the method comprising the determination of the position of the torso on a first image, in which method a virtual reference frame is associated with the torso on said first image, and in which method, for a second image, a new position of the virtual reference frame is determined on said second image, and, a relative position of the head with respect to said new position of the virtual reference frame is measured by comparison with the position of the virtual reference frame on said first image, so as to determine independently the movements of the head and the torso.
