Abstract

See full text

A touch interface includes a plate, at least one actuation transducer, at least one detector, and an amplification circuit. The plate defines a contact surface intended to be touched by an external body. The at least one actuation transducer is configured to make the plate vibrate as a function of an activation signal. The at least one detector is configured to detect an amplitude of a vibration of the plate and to generate a detection signal dependent on the detected vibration amplitude. The amplification circuit extends between an input and an output. The input is linked to the detector, and the output is linked to the actuation transducer. The interface also includes a processing unit configured to estimate an intensity of a pressing force exerted on the contact surface by the external body and to generate a force signal depending on the estimated intensity of the force.
