Abstract
The invention relates to a method for tracking an end of a utensil equipped with a magnetic object, wherein a parameter K(tn) representative of a contact between the end and a reference surface of a touch sensor is determined, and when contact is detected: an actual value D(k+1) of the distance Dbetween the end and the magnetic object is determined, on the basis of a value DI(k+1) of a distance, referred to as the projected distance DI between the position PA(tn) of the magnetic object and a position PI(tn) of a point of intersection between the reference surface and a straight line collinear with the magnetic moment m(tn), then the recorded value of the distance Dis updated on the basis of the actual determined value D(k+1) of the distance D
