Abstract

L'invention concerne un dispositif électronique disposant d'un écran tactile et comprenant : un actionneur qui fait vibrer l'écran tactile; et une unité de commande d'activation qui reçoit, d'un serveur sur un réseau, des informations de lien associant les fonctions du dispositif électronique et des modèles de vibration en fonction de l'apparition d'un événement préétabli, et, lorsque les fonctions du dispositif électronique sont choisies suite à l'apparition de l'événement, applique un signal d'activation à l'actionneur, à l'aide du modèle de vibration indiqué dans les informations de lien. Le signal d'activation est l'un quelconque parmi : un premier signal d'activation qui répète une onde sinusoïdale de f0 × m/n (m et n étant des entiers naturels et m ≠n) m fois, lorsque la fréquence de résonance de l'actionneur est f0; un second signal d'activation qui est une onde sinusoïdale de la fréquence de résonance f0 de l'actionneur et qui se termine au niveau d'un point différent du centre de l'amplitude de l'onde sinusoïdale; et un troisième signal d'activation qui est une vibration répétant m fois une forme d'onde présentant une phase décalée de π/2 de l'onde sinusoïdale de f0 × m/n (m et n étant des entiers naturels et m ≠n), lorsque la fréquence de résonance de l'actionneur est f0, et se terminant au niveau d'un point différent du centre de l'amplitude de la vibration.
