A method and system for time-motion compensation for use with head mounted displays is disclosed. According to the method, a remote camera captures an image for display on a head-mounted display (HMD) including a viewing window. The image and camera position data is transmitted to a system including the HMD for display to a wearer of the HMD. The HMD position is determined. An offset between the HMD position and a known position of the HMD is determined as is an offset between the camera position and a known position of the camera. The image is offset relative to the viewing window of the image based on the difference between the two determined offsets.

L'invention concerne un procédé et un système de correction de temps et de mouvement conçus pour être utilisés sur des affichages montés sur la tête. D'après ce procédé, une caméra à distance prend une image afin de l'afficher sur un affichage monté sur la tête (HMD) comprenant une fenêtre de visionnement. Les données d'image et de position de la caméra sont transmises à un système comportant le (HMD) afin de les afficher pour l'utilisateur du HMD. On détermine la position de ce dernier. On détermine un décalage entre la position du HMD et une position connue du HMD, ainsi qu'un décalage entre la position de la caméra et une position connue de la caméra. Cette image est décalée par rapport à la fenêtre de visionnement de l'image en fonction de la différence entre les deux décalages déterminés.
