Abstract (en)
[origin: WO2022090090A1] Method for implementing a touch device (1), the touch device (1) comprising: - a panel (10), comprising at least one texturization area (10') to which a texturization pattern (M, M1, M2) is assigned, the panel being intended to be touched by an external body; - at least one transducer (12), configured so as to set the panel (10) in vibration at an ultrasonic vibration frequency, the transducer being configured so as to be controlled by an activation signal; the method comprising: a) moving an external body (9) along the texturization area (10'); b) determining a position (S(t)) of the external body on the texturization area (10'); c) measuring a speed (V(t)) of the external body along the panel; d) when the external body moves along the texturization area, generating an activation signal (Act(t)), so as to activate the transducer (12) or each transducer; the method being characterized in that: the texturization pattern is oriented with respect to a reference axis; step c) comprises: • taking into consideration a reference axis (R); • measuring a component of the speed (VR) of the external body along the reference axis; during step d), the activation signal depends on the texturization pattern and on the component of the speed of the external body on the reference axis.
