Abstract

La présente invention concerne un dispositif informatique destiné à fournir un apprentissage de perception visuelle et un procédé et un programme, fondés sur un dispositif d'affichage monté sur la tête, destinés à fournir un apprentissage de perception visuelle. Le procédé, fondé sur un dispositif d'affichage monté sur la tête, destiné à fournir un apprentissage de perception visuelle selon un mode de réalisation de la présente invention comprend : une étape (S200) dans laquelle un ordinateur fournit un premier objet sur un premier écran du dispositif d'affichage monté sur la tête et fournit un second objet sur un second écran du dispositif d'affichage monté sur la tête ; une étape (S400 ; une étape de réception d'opération d'utilisateur) dans laquelle l'ordinateur reçoit, d'un utilisateur, une opération pour commander la relation de position entre le premier objet et le second objet ; une étape (S600 ; une étape de changement de positions des écrans) dans laquelle l'ordinateur modifie les positions des premier et second écrans en fonction de l'opération ; et une étape (S800) dans laquelle un contenu de perception visuelle est émis dans le champ de vision d'un patient, comprenant une zone de déficience visuelle, sur la base de la direction centrale du champ visuel.
