Title
(EN) HEAD MOUNTED DISPLAY WITH FULL FIELD OF VIEW AND HIGH RESOLUTION
(FR) VISIOCASQUE A CHAMP COMPLET DE VISUALISATION ET HAUTE RESOLUTION
Abstract
(EN)
A head mounted virtual environment display with high visual resolution and a full field of view is disclosed. The display uses an optical system in which the video displays and corresponding lendses are positioned tangent to hemispheres with centers located at the centers of rotation of a user's eyes. Centering the optical system on the center of rotation of the eye allows both a full field of view and high fidelity visual resolution, without compromising visual resolution. A multi-panel video wall design for the video displays allows each lens facet to image a miniature flat panel display at optical infinity. The flat panel displays are centered on the optical axes of the lens facets. A parallel graphics architecture uses data from high resolution and accuracy head trackers and built-in eye trackers to generate high detail 3D models at high frame rates with minimal perceptible lag. Resolution for central vision is optimized with a roaming high level of detail window, and slip artifacts associated with rapid head movements are eliminated using freeze-frame.

L'invention concerne un visiocasque à environnement virtuel à haute résolution virtuelle et champ complet de visualisation. L'affichage utilise un système optique dans lequel les affichages vidéo et les lentilles correspondantes sont positionnés de manière tangentielle par rapport aux hémisphères avec des centres situés sur le centre de rotation des yeux d'un utilisateur. Le centrage du système optique sur le centre de rotation de l'oeil permet d'obtenir à la fois un champ complet de visualisation et une résolution haute fidélité sans compromettre la résolution visuelle. La conception de la paroi vidéo à multiples panneaux permet à chaque facette de la lentille de représenter un affichage à panneau plat miniature à infinité optique. Les affichages à panneaux plats sont centrés sur les axes optiques des facettes de la lentille. Une architecture graphique parallèle utilise les données de dispositifs de suivi du visiocasque haute résolution et haute précision et de dispositifs de suivi visuels intégrés pour générer des modèles 3D hautement détaillés à des fréquences de trames élevées avec une persistance faiblement perceptible. La résolution pour la vision centrale est optimisée avec un niveau élevé d'itinérance de fenêtre détaillée, et les artéfacts de glissement associés à de rapides mouvements de tête sont éliminés par arrêt d'image.
