Abstract

L'invention concerne un programme, un processeur étant conçu pour exécuter : une étape consistant à définir un espace virtuel ; une étape consistant à accepter une entrée d'une image obtenue par imagerie avec une caméra à 360° ; une étape consistant à agencer un point de vue virtuel dans l'espace virtuel ; une étape consistant à agencer un objet d'affichage dans l'espace virtuel ; une étape consistant à afficher l'image entrée au niveau de l'objet d'affichage ; une étape consistant à spécifier un sujet de suivi dans l'espace virtuel ; une étape consistant à détecter un mouvement de la tête d'un utilisateur avec lequel un dispositif de tête a été associé ; une étape consistant à commander le champ de vision à partir du point de vue virtuel en fonction du mouvement de la tête ; une étape consistant à commander la rotation de l'espace virtuel, si le sujet de suivi n'est pas inclus dans le champ de vision à partir du point de vue virtuel, de telle sorte que le sujet de suivi sera inclus dans le champ de vision à partir du point de vue virtuel ; et une étape consistant à afficher, au niveau du dispositif de tête, une image de champ de vision correspondant au champ de vision à partir du point de vue virtuel.
