Ring-shaped touch sensor and associated human-machine interface

Abstract

The present invention relates to a ring-shaped sensor assembly (R), the assembly comprising: an annular element (ANN) having a substantially cylindrical shape; at least two deformation sensors (SENS1, SENS2, SENS3) mounted on the annular element on at least two radii of the annular element, the two radii being angularly distinct from each other, so that at least two sensors are sensitive to the overall deformation of the annular element; and an electronic module (EL) configured to generate a detection signal representing the overall deformation of the annular element in response to the step of processing at least two signals transmitted by the at least two deformation sensors (SENS1, SENS2, SENS3), respectively.
