Abstract

L'invention concerne un terminal portable qui empêche de détecter un contact autre que le contact d'une main. Un Smartphone (1) comprend un capteur tactile (31) monté sur le boîtier du Smartphone (1) et un module de détection d'état (33) qui détecte si l'état des alentours du Smartphone ou l'état du Smartphone lui-même correspond, ou non, à un état prescrit. Quand un contact avec le capteur tactile (31) est détecté et que le module de détection d'état (33) a détecté l'état prescrit pendant qu'un module d'affichage (34) est dans un état dormant, le Smartphone commute l'état dormant du module d'affichage (34) à un état d'affichage.
