Abstract
Method for determining the orientation of the trajectory followed by a pedestrian, associated with a trajectory frame, with respect to a reference frame is provided. At least one motion sensor associated with the pedestrian generates data representative of the motion of the sensor housing on the basis of said sensor assembly in the reference frame. A first rotation transformation operator representative of the orientation of the reference frame with respect to the trajectory frame is calculated. The data representative of the motion after transformation by said first operator exhibits at least one characteristic of a set of characteristics which are representative of signals of walking or running motion of a pedestrian and are expressed in the pedestrian frame.
