Claim 6:
7. The method of claim 6, wherein:
when the external body passes on either side of the notch of the at least one notch, the modulation function successively comprises:
an anterior phase when the external body approaches the notch of the at least one notch;
a notch phase when the external body crosses the notch of the at least one notch; and
a posterior phase when the external body moves away from the notch of the at least one notch;

a feeling of the notch, of the at least one notch, by the user depends on the modulation function during the anterior phase, the notch phase, and the posterior phase; and
the modulation function is such that in the notch phase the modulation function changes over a wider range of variation than in the anterior phase and in the posterior phase.
