Abstract

L'invention concerne un dispositif de détermination d'opération tactile (30) comprenant : une unité de détection de position d'indicateur (33) qui détecte la position d'un indicateur dans un espace dans lequel est disposé un dispositif d'entrée tactile (100), ledit dispositif d'entrée tactile étant équipé d'une première surface d'entrée tactile (11) et d'une première unité de détection de coordonnées tactiles (12) ; et une unité de détermination de validité (34) qui détermine la validité d'un premier contact tactile sur la première surface d'entrée tactile (11) et d'un second contact tactile sur une seconde surface d'entrée tactile (21). L'unité de détermination de validité (34) détermine la validité du premier contact tactile et du second contact tactile sur la base du changement de la position de l'indicateur dans une séquence temporelle avant que le premier contact tactile et le second contact tactile soient réalisés, lorsque le temps entre le premier contact tactile et le second contact tactile est plus court qu'un temps seuil prédéfini.
