Abstract

Des modes de réalisation de la présente invention concernent un système de projection, un procédé, un serveur et une interface de commande. Le système de projection comprend un dispositif d'affichage, un film de projection, un projecteur et ledit système affiche simultanément respectivement des premières données vidéo et des deuxièmes données vidéo à l'aide du dispositif d'affichage et du film de projection. Les premières données vidéo et les deuxièmes données vidéo comprennent respectivement des données vidéo des images vidéo à différentes plages de profondeur. Du fait qu'une ligne de temps utilisée par les premières données vidéo et les deuxièmes données vidéo est la même que celle des images vidéo et que l'affichage desdites premières et deuxièmes données vidéo est effectuée simultanément, lors du processus d'affichage par projection, un objet cible apparaîtra dans le dispositif d'affichage lorsque l'objet cible se trouve dans une première plage et l'objet cible passera vers le film de projection lorsque l'objet cible se déplace dans une deuxième plage. Lorsque l'objet cible se déplace, un utilisateur regardant l'affichage de projection aura l'impression que l'objet cible subit un changement de profondeur lorsque ledit objet cible se déplace entre le dispositif d'affichage et le film de projection, ce qui permet de réaliser un effet d'affichage tridimensionnel, de fournir une expérience visuelle plus immersive à l'utilisateur et d'améliorer l'expérience utilisateur.
