Claim 13:
14. The method of claim 1, wherein:
the texturing pattern is oriented relative to a first reference axis and a second reference axis;
measuring the speed of the external body along the plate comprises measuring a first projection of the speed on the first reference axis and a second projection of the speed on the second reference axis; and
generating the activation signal comprises, during the movement of the external body:
generating a first activation signal that is formed by a first periodic wave carrier modulated by a first modulation function, a temporal shape of the first modulation function depending on the first projection of the speed;
generating a second activation signal that is formed by a second periodic carrier modulated by a second modulation function, a temporal shape of the second modulation function depending on the second projection of the speed; and
combining the first activation signal and the second activation signal to form the activation signal.
