Abstract
A method for implementing a touch device—having a plate, touchable by an external body and having at least one texturing area assigned with a texturing pattern oriented relative to a reference axis, and at least one transducer configured to vibrate the plate at an ultrasonic vibration frequency and controllable by an activation signal—includes moving the external body along the texturing area; determining a position of the external body on the texturing area; measuring a speed of the external body along the plate; and, when the external body moves along the texturing area, generating the activation signal to activate the, or each, transducer. Measuring the speed takes into account the reference axis and measuring a component of the speed of the external body over the reference axis. The activation signal depends on the texturing pattern and on the component of the speed.
