Abstract

L'invention concerne un dispositif de commande de pilotage et analogues qui permettent de détecter, par une sensation de toucher, si une région d'affichage spécifique est ou non contenue dans une section d'affichage. Le dispositif de commande de pilotage comprend : une unité de stockage dans laquelle des données d'image d'une image pouvant être amenée à défiler et des données de position sont stockées en association les unes avec les autres, les données d'image ayant un bloc pour afficher une image ou signe prédéterminé(e) et étant conçues pour avoir une partie de l'image affichée dans une section d'affichage, et les données de position représentant la position du bloc dans l'image ; une unité de calcul qui détermine une quantité d'opération et de direction d'une opération de défilement ; et une unité de commande de pilotage qui, lorsque l'opération de défilement est réalisée, pilote un élément de vibration à l'aide d'un signal de pilotage pour amener une vibration spécifique dans la plage d'ultrasons à être produite sur une surface d'exploitation, sur la base des données de position, et de la quantité d'opération et de la direction d'opération de l'opération de défilement, l'élément de vibration étant piloté à l'aide d'un premier motif lorsque l'une d'une extrémité gauche et d'une extrémité droite du bloc ou l'une d'une extrémité supérieure et d'une extrémité inférieure du bloc n'est pas affichée dans la section d'affichage, et l'élément de vibration étant piloté à l'aide d'un second motif lorsque l'une de l'extrémité gauche et de l'extrémité droite ou l'une de l'extrémité supérieure et de l'extrémité inférieure est affichée dans la section d'affichage.
