Title
(EN) IMPAIRMENT DETECTION WITH ENVIRONMENTAL CONSIDERATIONS
(FR) DÉTECTION D'ALTÉRATIONS TENANT COMPTE DE CONSIDÉRATIONS ENVIRONNEMENTALES
Abstract
(EN) A method and system for monitoring impairment indicators. The method comprises, during a first time window, measuring a first movement signal related to movement of a person with a movement sensor associated with the person, and measuring a first environmental signal with an environmental sensor. The method further comprises electronically storing at least one numerical descriptor derived from the first movement signal and the first environmental signal as reference data for the person. The method further includes, during a second time window, measuring a second movement signal related to movement of the person with the movement sensor and measuring a second environmental signal with the environmental sensor; and comparing at least one numerical descriptor derived from the second movement signal and the second environmental signal to the reference data to identify an impairment indicator.
(FR) L'invention concerne un procédé et un système de surveillance d'indicateurs d'altérations. Ce procédé comprend, pendant un premier créneau temporel, la mesure d'un premier signal de mouvement lié au mouvement d'une personne au moyen d'un capteur de mouvement associé à la personne, et la mesure d'un premier signal d'environnement au moyen d'un capteur environnemental. Le procédé comprend également l'enregistrement électronique d'au moins un descripteur numérique dérivé du premier signal de mouvement et du premier signal d'environnement comme données de référence pour la personne. Le procédé comprend également, pendant un deuxième créneau temporel, la mesure d'un deuxième signal de mouvement lié au mouvement de la personne au moyen du capteur de mouvement, et la mesure d'un deuxième signal d'environnement au moyen du capteur d'environnement; et la comparaison d'au moins un descripteur numérique dérivé du deuxième signal de mouvement et du deuxième signal d'environnement avec les données de référence afin d'identifier un indicateur d'altération.
