Abstract: A touch interface, intended to control a device and to be touched by an external body, includes a plate, at least one transducer, a control member, a sensor, and a control unit. The at least one transducer is configured to apply a variable amplitude pressure to the plate to vibrate the plate. The control member extends from the plate, between a proximal surface, integral with the plate, and a distal surface. The control member is intended to be in contact with an external body. The sensor is configured to emit a state signal. The state signal is representative of contact of the external body on the control member. The control unit is connected to the sensor and is configured to send, on the basis of the state signal, an activation signal to at least one transducer, to form a vibration propagating along the plate to the control member.
