Abstract

La présente invention concerne un dispositif à écran tactile et un procédé d'ajustement de la dimension d'un écran tactile. Si une première entrée tactile est détectée sur l'écran tactile puis qu'une seconde entrée tactile est détectée immédiatement après, des procédés selon certains modes de réalisation de la présente invention peuvent permettre à une trajectoire de la première entrée tactile d'être suivie de façon à ajuster la dimension d'écran sur la base de la trajectoire de la première entrée tactile suivie. Ainsi, selon lesdits modes de réalisation de la présente invention, une technique peut être fournie pour un utilisateur pour que celui-ci soit apte à ajuster facilement la dimension d'écran d'un dispositif à écran tactile sur la base d'une simple entrée tactile.
