Abstract

On décrit un dispositif (1) de mesure de mouvements corporels permettant de détecter l’équilibre lors de mouvements corporels même en l’absence d’un capteur de pression installé. Le dispositif (1) de mesure de mouvements corporels est équipé d’une unité (12) de détection d’accélération servant à détecter une variation d’accélération due à la marche, une unité (14) de calcul servant à détecter l’équilibre lors de la marche à partir d’un signal d’accélération détecté par l’unité (12) de détection d’accélération, et une unité (13) d’affichage servant à effectuer des sorties en fonction de l’équilibre détecté lors de la marche. L’unité (14) de calcul exécute des étapes S8, S12 consistant à reconnaître des unités de pas de marche à partir du signal d’accélération et à acquérir PPimpair, PPpair, Timpair et Tpair qui sont des informations par jambe, et des étapes S9, S13, S16 consistant à détecter l’équilibre lors de la marche en fonction des informations par jambe.
