Abstract

Le dispositif d'entrée tactile (10) d'après la présente invention comprend une unité de capteur de pression (20), une unité de capteur de position (30), une unité d'écran d'affichage (40) et un module de circuit de calcul (60). Le module de circuit de calcul (60) comprend une unité de traitement de pression (61), une unité de traitement de position (62), une unité de calcul d'action (63) et une unité de traitement d'affichage (64). L'unité de capteur de pression (20) et l'unité de traitement de pression (61) détectent des opérations de commande de pression effectuées sur une surface de commande. L'unité de capteur de position (30) et l'unité de traitement de position (62) détectent une pluralité de positions sur la surface de commande sur laquelle des opérations de commande tactile ont été effectuées. L'unité de calcul d'action (63) accepte une opération de commande de rotation et/ou une opération de commande de rétrécissement sur la base des opérations de commande de pression susmentionnées et des variations des positions susmentionnées.
