SYSTEM AND METHOD FOR COUNTING THE CHANGES IN DIRECTION OF A PERSON

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.
