Abstract

La présente invention porte sur un système (100), un procédé (900) et un appareil (110) servant à afficher une image (880). Le système (100) peut utiliser un miroir incurvé (420) en association avec une plaque partiellement transparente (430) pour projeter une image directement sur les yeux (92) d'un utilisateur (90). La combinaison miroir incurvé (420) et plaque (430) peut également servir à donner des fonctions supplémentaires à un appareil de visée à VRD (116), par exemple la possibilité de fonctionner en mode suivi (123), pour le suivi des yeux (92) de la personne qui regarde (96), et la possibilité de fonctionner en mode augmentation (122), pour que la personne qui regarde (96) voie l'image (880) affichée par-dessus la vue de son environnement physique (650).
