Abstract
A system for counting a basic displacement of a person includes a housing (BT) and a fixing device (EF) for securely mounting the housing (BT) on the person. Within the housing are a magnetometer for measuring the direction of the terrestrial magnetic field in the reference frame of the housing, a device for determining a quantity representative of the inclination of the measured magnetic field with respect to the vertical, and a device for detecting a change of orientation of an orthogonal projection of the direction of the terrestrial magnetic field in a horizontal planar reference frame having axes of constant directions and tied in translation to the person, on the basis of the measured direction of the magnetic field and of the quantity representative of the inclination of the magnetic field with respect to the vertical.
