Abstract

La présente invention concerne un procédé de commande tactile, ainsi qu'un appareil et un système de traitement. Le procédé de commande tactile comprend : le calcul d'une première position de coordonnée en fonction d'une première zone tactile détectée sur un écran tactile; la commande de l'affichage d'un curseur sur l'écran tactile en dehors de la première zone tactile en fonction de la première position de coordonnée; et la commande du mouvement du curseur en fonction de la vitesse et de la direction de déplacement de la première position de coordonnée. Le procédé de commande tactile, ainsi que l'appareil et le système de traitement commandent le mouvement du curseur affiché sur l'écran tactile par détection de la vitesse et de la direction de déplacement de la position de coordonnée obtenue par le calcul tactile, ce qui déplace le curseur jusqu'à une position définie, et peuvent parvenir à ce que le curseur sur l'écran tactile soit déplacé précisément jusqu'à une position de sélection souhaitée afin d'améliorer la précision de la commande tactile pour l'écran tactile.
