Abstract

La présente divulgation concerne un casque de réalité virtuelle (10) qui comprend une zone de lentille primaire (16, 18) et une zone de lentille périphérique (20, 22). Le casque de réalité virtuelle (10) peut également comprendre un ou plusieurs écrans d'affichage primaires (30) alignés avec les zones de lentilles primaires (16, 18) et de multiples écrans d'affichage secondaires (32) alignés avec les zones de lentilles périphériques (20, 22). Les zones de lentilles périphériques (20, 22) peuvent comprendre une texture semi-transparente pour déformer des images visualisées à travers la zone de lentille périphérique (20, 22) pour apparaître comme par l'intermédiaire d'une vue de vision périphérique et pour compléter des images principales vues à travers la zone de lentille primaire (16, 18).
