Abstract

L'invention concerne un appareil (1) d'affichage comportant une unité (10) de saisie d'opérations, une unité (20) de commande, une unité (21) de stockage, une RAM (22), une unité (30) d'affichage, une unité (60) de communications de LAN sans fil, une unité (61) de communications 3G, et une batterie (70). L'unité (10) de saisie d'opérations est dotée d'un capteur (11P) d'appui et d'un capteur tactile (11D). Lorsqu'une surface (101) d'opération de l'unité (10) de saisie d'opérations est pressée, le capteur (11P) d'appui émet vers l'unité (20) de commande un signal de détection d'appui à un niveau de signal (DSp) correspondant à une quantité d'appui (force d'appui). Lorsqu'il est déterminé que le niveau de signal (DSp) du signal de détection d'appui émanant du capteur (11P) d'appui est supérieur ou égal à une valeur seuil prédéterminée, l'unité (20) de commande conserve dans la RAM (22) des informations de page qui indiquent le contenu d'une première page. Lorsqu'il est déterminé que le niveau de signal (DSp) du signal de détection d'appui émanant du capteur (11P) d'appui est supérieur ou égal à la valeur seuil prédéterminée, l'unité (20) de commande donne pour consigne à l'unité (30) d'affichage d'afficher la première page.
