1. A method for determining an elementary angle of a control trajectory on a touch surface, comprising:

  • measuring two values of elementary displacements along two perpendicular axes in the course of a predetermined duration;

    comparing said two values of elementary displacements with spans of unit values of elementary displacements of a reference data table; and

    ascribing a reference datum representative of an angle to an elementary angle of the control trajectory.
