Title (EN) TOUCH POSITION DETERMINING DEVICE AND METHOD, AND ELECTRONIC TOUCH-SENSITIVE DEVICE
(FR) PROCEDE ET DISPOSITIF PERMETTANT DE DETERMINER LA POSITION DU TOUCHER ET DISPOSITIF ELECTRONIQUE TACTILE
Abstract: front page image
(EN)In a device (2) for determining the position (P1(x, y) ) of a touch on a contact surface (1a), a plurality of vibration sensors (4) are configured to detect mechanical vibrations (9) generated by the touch on the contact surface (1a) and to generate corresponding vibration signals, and a processing circuit (6) is connected to the vibration sensors (4) and is configured to determine the touch position (P1 (x, y) ) via a time-of-f light algorithm, based on differences between times of detection (t1, t2, t3) of the mechanical vibrations (9) by the vibration sensors (4).
(FR)Dans un dispositif (2) conçu pour déterminer la position (P1(X, y) ) d'un toucher sur une surface de contact (1a), plusieurs capteurs de vibrations (4) permettent de détecter des vibrations mécaniques (9) engendrées par le toucher sur la surface de contact (1a) et produisent des signaux vibrants correspondants. Un circuit de traitement (6) est relié aux capteurs de vibrations (4) et il permet de déterminer la position du toucher (P1(x, y)) grâce à un algorithme durée de trajet, fondé sur les différences entre les temps de détection (t1, t2, t3) des vibrations mécaniques (9) par les capteurs de vibrations (4).
