Abstract
This method of converting a displacement of a magnetic object into a signal directly perceptible by a human being, comprises: —the acquisition (32) of a temporal succession of measurements of a magnetic field modified by the displacements of the object during a sliding time window of predetermined duration, —the construction (34) on the basis of this acquired temporal succession of measurements of several signals each representing a characteristic of the measured magnetic field dependent on a corresponding characteristic of the displacement of the object, and —the adjustment (50) of several parameters of the directly perceptible signal as a function of the signals so as to render these characteristics directly perceptible.
