Abstract

L'invention concerne un manège, un système de manège et un procédé permettant la mesure et la correction de position en temps réel. Le procédé permettant la mesure de position en temps réel d'un manège sous la commande d'un dispositif informatique peut comprendre les étapes consistant : à recevoir un signal de codeur provenant d'un codeur connecté à au moins une roue du manège ; à recevoir des signaux infrarouges émis respectivement par une pluralité de capteurs infrarouges provenant de la pluralité de capteurs infrarouges prévus pour être espacés les uns des autres sur une piste entraînant le mouvement du manège ; à calculer une valeur de position relative du manège sur la base du signal de codeur reçu ; à calculer une valeur de position absolue du manège sur la base des signaux infrarouges reçus ; à calculer la différence entre la valeur de position relative et la valeur de position absolue ; et à générer, sur la base de la différence, un signal de commande capable de commander la vitesse de lecture du contenu de réalité virtuelle.
