Title
(EN) MULTI-MODAL HAND LOCATION AND ORIENTATION FOR AVATAR MOVEMENT
(FR) LOCALISATION ET ORIENTATION DE MAIN MULTIMODALES POUR UN MOUVEMENT D'AVATAR
Abstract
(EN)
Examples of systems and methods for improved hand tracking of a user in a mixed reality environment are disclosed. The systems and methods may be configured to estimate the hand pose and shape of a user's hands for applications such as animating a hand on a user's avatar. Data from multiple sources, such as a totem internal measurement unit ("IMU"), external totem location tracking, vision cameras, and depth sensors, may be manipulated using a set of rules that are based on historical data, ergonomics data, and motion data.

Selon l'invention, des systèmes et des procédés donnés à titre d'exemple permettent un suivi amélioré de la main d'un utilisateur dans un environnement de réalité mixte. Les systèmes et les procédés peuvent être configurés pour estimer la position et la forme des mains d'un utilisateur pour des applications telles que l'animation d'une main sur un avatar de l'utilisateur. Des données provenant de multiples sources, telles qu'une unité de mesure interne de totem ("IMU"), un suivi d'emplacement de totem externe, des caméras de vision et des capteurs de profondeur, peuvent être manipulées à l'aide d'un ensemble de règles qui sont basées sur des données historiques, des données d'ergonomie et des données de mouvement.
