Abstract

La présente invention concerne un procédé d'entrée de geste et un dispositif électronique. Le procédé consiste à : acquérir, par un dispositif électronique, un premier geste, le premier geste comprenant un premier sous-geste et un second sous-geste ; lorsque le premier sous-geste correspond à un geste prédéfini, reconnaître une fonction correspondant au second sous-geste ; et exécuter la fonction correspondant au second sous-geste. Un geste de mise en œuvre selon la présente invention peut comprendre un geste de réveil, c'est-à-dire qu'un geste initial du geste de mise en œuvre peut être le geste de réveil, réduisant ainsi le retard de mise en œuvre gestuelle, augmentant l'efficacité de réponse du dispositif électronique, et augmentant l'efficacité d'interaction entre un utilisateur et le dispositif électronique.
