Title (EN) RANGE FINDING AND ACCESSORY TRACKING FOR HEAD-MOUNTED DISPLAY SYSTEMS
(FR) TÉLÉMÉTRIE ET SUIVI D'ACCESSOIRE DE SYSTÈMES VISIOCASQUES
Abstract:
(EN) Range finding methods and apparatus that may be implemented by VR/MR systems that include a head-mounted display (HMD) and an accessory that the user holds or wears. Range finding sensors (e.g., ultrasonic transducers) may be included on the HMD and on the accessory and used to track distances to and relative position of walls, objects, and other obstacles within constrained physical environments such as rooms, gyms, yards, or fields, or in unconstrained physical environments. Range finding information from the sensors on the HMD and accessory can be used to generate a 3D map of the user's environment that can be used for various purposes in the VR/MR system. In addition to mapping the user's environment, the range finding methods and apparatus may also be used to track the relative position of the accessory with respect to the HMD.
(FR) L'invention concerne des procédés et un appareil de télémétrie qui peuvent être mis en œuvre par des systèmes VR/MR qui comprennent un visiocasque (HMD) et un accessoire que l'utilisateur tient ou porte. Des capteurs de télémétrie (par exemple, des transducteurs ultrasonores) peuvent être compris sur le HMD et sur l'accessoire et servir à suivre des distances par rapport à des murs, des objets, et d'autres obstacles et leur position relative dans des environnements physiques contraints tels que des pièces, des gymnases, des cours, ou des champs, ou dans des environnements physiques non contraints. Des informations de télémétrie provenant des capteurs du HMD et de l'accessoire peuvent servir à générer une carte 3D de l'environnement de l'utilisateur qui peut servir à diverses fins dans le système VR/MR. En plus de la cartographie de l'environnement de l'utilisateur, les procédés et l'appareil de télémétrie peuvent également servir à suivre la position relative de l'accessoire par rapport au HMD.
