Abstract

L'invention concerne un procédé, un appareil et un dispositif de traitement de commande d'effacement. Le procédé consiste à : détecter le trajet de déplacement d'une commande d'effacement se déplaçant d'une première position à une seconde position ; obtenir l'angle de décalage de la commande d'effacement sur la base du trajet de déplacement, l'angle de décalage étant l'angle inclus entre la commande d'effacement et la direction verticale ; et afficher une table de bits de la commande d'effacement à la seconde position sur la base de l'angle de décalage. La présente invention résout le problème technique selon lequel la direction d'affichage en mode point de la commande d'effacement est fixe et l'effet d'effacement est médiocre dans l'état de la technique.
