    摘要: The invention relates to a system for counting a basic movement of a person, including a housing (BT) and attachment means (EF) for rigidly connecting said housing (BT) to a portion of the body of said person, including: means for measuring the direction of earth's magnetic field in the frame of reference of the housing; means for determining (DET_INC) a quantity representative of the inclination of the measured magnetic field relative to the vertical; and first means for detecting (DETEC1) a change in the orientation of an orthogonal projection of said direction of earth's magnetic field in a horizontal planar frame of reference having constant directional axes and linked in translation to said person on the basis of said measured direction of the magnetic field and on said quantity representative of the magnetic field inclination relative to the vertical.

    摘要: The invention relates to a device and to a method for characterising movements made by an object, in particular a limb of a human being, fitted with at least one accelerometer sensor. The invention is particularly useful for determining the direction, the orientation and the length of the steps of said human being. The invention uses algorithms for processing the signals from the sensor in order to segment the steps by detecting the lifting and lowering of said limb from and on the floor or ground by comparing output signals from the sensor to thresholds, determine the direction and the orientation of the steps by comparing the maximum values of the signals along two axes substantially parallel to the walking plane, and calculate the length of a step by double integration of the signals according to the direction of the step. The invention can also be used for hand movements having variation characteristics close to those of steps.

    摘要: The invention relates to a system and method for recognizing gestures of an entity, in particular a human being, and optionally controlling an electrical or electronic apparatus or system. The invention uses sensors which measure signals, said signals preferably being representative of inertial data on the movements of said entity, and implements a process for developing a dictionary of said gestures to be recognized and an algorithm for recognition from among the classes of gestures of said dictionary. The implemented algorithm is preferably a dynamic time warping algorithm. The system of the invention implements preprocessing such as the removal of signals sensed during periods of inactivity of the entity, subsampling the signals, and normalizing the measurements by means of reduction, and preferably uses, for classifying gestures, specific distance-calculating modes and merging or voting modes among the various measurements of the sensors.

    摘要: L'invention est un procédé de détermination d'un niveau de stress d'un individu, en fonction d'un paramètre physiologique de l'individu, le procédé comportant :
    a) mesure d'une valeur du paramètre physiologique dans différentes périodes de calibration durant une période temporelle de calibration ;
    b) définition d'une plage de variation des valeurs du paramètre physiologique mesurées lors des périodes de calibration ;
    c) en fonction de la plage de variation, établissement d'une fonction d'appartenance, déterminant un niveau de stress de l'individu en fonction de la valeur du paramètre physiologique, le niveau de stress déterminé par la fonction d'appartenance pouvant évoluer entre :
    - un niveau de repos, correspondant à un état de repos de l'individu ;
    - un niveau de stress, correspondant à un état de stress de l'individu ;
    - et au moins un niveau intermédiaire, compris entre le niveau de repos et le niveau de stress ;

    d) suite à l'étape c), mesure d'une valeur du paramètre physiologique durant une période de mesure, et détermination du niveau de stress de l'individu en appliquant la fonction d'appartenance à la valeur du paramètre mesurée ;
