Abstract

La présente invention concerne un terminal mobile comprenant une unité d'affichage souple, et son procédé de commande. Ledit terminal mobile comprend : un corps de terminal qui possède une surface avant, des surfaces latérales et une surface arrière et qui est souple, de telle sorte qu'au moins une de ses parties est pliable ; une unité d'affichage se trouvant sur la surface avant et comportant une première partie et une seconde partie conçues de manière à ce que la seconde partie puisse tourner par rapport à une partie bord située sur un côté de la première partie afin que la première partie soit recouverte par la seconde ou ne soit pas recouverte par la seconde ; une première unité de détection placée sur l'extrémité gauche du corps de terminal et générant un premier signal sur la base d'un mouvement de l'extrémité gauche ; une seconde unité de détection placée à l'extrémité droite du corps de terminal et générant un second signal sur la base d'un mouvement de l'extrémité droite ; et une unité de commande destinée à commander au moins une des fonctions exécutables sur le terminal selon le premier et le second signal.
