Abstract

L'invention concerne un procédé et un dispositif de commutation de mode. Le procédé consiste : à détecter, par un écran tactile capacitif d'un terminal, un changement de courant de l'écran tactile capacitif provoqué par un objet externe qui n'est pas en contact avec l'écran tactile capacitif; et à commuter entre des modes correspondants en fonction du changement de courant. Au moyen de la présente invention, on résout le problème selon lequel le temps de fonctionnement est consommé en raison du fait que des modes d'un terminal mobile doivent être commutés manuellement par un utilisateur, en réalisant ainsi la commutation automatique de modes et en améliorant l'expérience utilisateur.
