Claim 18:
19. A touch device comprising a plate that is touchable by an external body, the plate comprising at least one texturing area to which a virtual texturing pattern is assigned, the touch device further comprising:
at least one transducer configured to vibrate the plate;
a position sensor configured to generate a position signal, the position signal representing a position of the external body on the plate;
a calculation unit for determining a speed signal based on position signals that are respectively generated at different instants, the speed signal representing a speed of the external body along the plate; and
a control unit that is connected to the position sensor and to the calculation unit and configured to implement, as recited in claim 1, the generation of the activation signal based on the position signal generated from the position sensor and the speed signal determined from the calculation unit.
