Abstract

METHODE D’EVALUATION D’UNE POSTURE, DISPOSITIF D’EVALUATION ASSOCIÉ L’invention se rapporte à une méthode d’évaluation de la posture d’un utilisateur par un dispositif comprenant un accéléromètre, la méthode comprenant : Une étape d’établissement de scores d’inclinaison et de flexion réalisée à un instant courant puis à un instant immédiatement successif à partir d’amplitudes d’inclinaison et de flexion provenant d’une accélération mesurée par l’accéléromètre, Une étape de calcul de différence entre les scores à l’instant immédiatement successif à l’instant courant et à l’instant courant, Si au moins une des différences entre les scores est supérieure à un seuil, une étape d’établissement d’une note à partir des différences entre les scores Une étape d’évaluation de la posture de l’utilisateur par classification de la note établie. Figure à publier avec l’abrégé : Fig. 5aMETHOD FOR EVALUATING A POSTURE, ASSOCIATED EVALUATION DEVICE The invention relates to a method for evaluating the posture of a user by a device comprising an accelerometer, the method comprising: A step of establishing scores of inclination and flexion carried out at a current instant then at an immediately successive instant from amplitudes of inclination and flexion coming from an acceleration measured by the accelerometer, A step of calculating the difference between the scores at instant immediately successive to the current instant and the current instant, If at least one of the differences between the scores is greater than a threshold, a step of establishing a score from the differences between the scores A step of evaluation of the user's posture by classification of the established score. Figure to be published with the abstract: Fig. 5a
