Abstract

La présente invention concerne un système et un procédé de mesure de la posture du corps et de paramètres de santé d'une personne utilisant une chaise. La chaise comprend un réseau de détection, une unité de traitement, un dispositif informatique et un dispositif d'alarme. Le réseau de détection comprend une pluralité de détecteurs associés audit dispositif. Chaque détecteur fournit une sortie, indicatrice d'une réponse du détecteur à l'individu. Le réseau de détecteurs fournit un moyen d'estimer une attitude de position de l'individu sur la base des signaux émis par ladite pluralité de détecteurs. Le réseau de détecteurs comprend un ou plusieurs détecteurs de contact qui sont sensibles à des déformations structurelles ou géométriques.
