Abstract

L'invention concerne un dispositif de traitement d'informations, et analogue, permettant de distinguer avec précision un contact erroné sur un panneau tactile (11). Lorsque l'une d'une première opération de toucher ou d'une seconde opération de toucher détectée sur le panneau tactile (11) est une opération de toucher dans une zone prédéterminée, une unité de détermination de pression (323) calcule une différence de pression entre les opérations de toucher. Lorsque la différence de pression est supérieure ou égale à une valeur prédéterminée, une unité d'avertissement (324) invalide l'opération de toucher dans la zone prédéterminée.
