CA 2187026

A system is provided for tracking the three-dimensional position of an object within a three-dimensional region by triangulation techniques to generate signals corresponding to such three-dimensinal positions. The signals may be used to operate a variably operable system to create a virtual reality system. The triangulation means may comprise at least three ultrasound emitters cooperating with ultrasound receivers located on a body moving in the three-dimensional region. The signals are produced from multiplexed frequencies and/or intermediate signals may be projected using a triaxial accelerometer.

Système permettant de suivre la position tridimensionnelle d'un objet dans un espace tridimensionnel par technique de triangulation afin de générer des signaux correspondant à de telles positions. Ces signaux peuvent être utilisés pour commander une système à fonctionnement variable afin de créer un système de réalité virtuelle. Les moyens de triangulation peuvent comprendre au moins trois émetteurs d'ultrasons coopérant avec des récepteurs d'ultrasons situés sur un corps se déplaçant dans l'espace tridimensionnel. Les signaux sont produits à partir de fréquences multiplexées et/ou des signaux intermédiaires peuvent être émis au moyen d'un accéléromètre à trois axes.
