Title (EN) TOUCH INTERFACE INCLUDING A FORCE SENSOR
(FR) INTERFACE TACTILE COMPORTANT UN CAPTEUR DE FORCE
Abstract:
(EN) The invention is a touch interface having a contact surface that is able to be touched by an effector, a finger for example. The interface includes actuating transducers, piezoelectric transistors for example, allowing a standing flexural wave to be formed, in a resonant mode, extending over the length of the slab. The interface includes a detector for measuring the amplitude of the wave, and a detecting circuit for determining an attenuation signal, when the contact surface is touched by an effector. It includes a processing circuit for estimating a magnitude of the force exerted by the effector on the contact surface.
(FR) L'invention est une interface tactile, présentant une surface de contact apte à être touchée par un effecteur, par exemple un doigt. L'interface compote des transducteurs d'actionnement, par exemple des transducteurs piézoélectriques, permettant une formation d'une onde de flexion stationnaire, selon un mode de résonance, s'étendant le long de la plaque. L'interface comporte un détecteur pour mesurer l'amplitude de l'onde, ainsi qu'un circuit de détection pour déterminer un signal d'atténuation, lorsque la surface de contact est touchée par un effecteur. Elle comporte un circuit de traitement pour estimer une intensité de la force exercée par l'effecteur sur la surface de contact.
