Abstract

L'invention concerne un piano de poche. Dans le cas d'un piano de poche associé à un dispositif mobile de petite taille tel qu'un teléphone cellulaire, la limitation du petit écran rend difficile l'utilisation de tous les claviers de plusieurs largeurs d'octave ainsi que des tonalités dynamiques ou des tonalités de pédale. L'invention vise à résoudre ces inconvénients. Dans un mode de réalisation, un capteur de mouvement est destiné à détecter un mouvement. Lorsqu'un mouvement est détecté, l'affichage s'élargit en réponse à un signal de mouvement latéral, dans une direction latérale des claviers ainsi que sur la distance de mouvement. Des effets de pédale sont également générés en réponse à un signal de mouvement vertical. Chaque clavier comprend des zones avec différents niveaux dynamiques, permettant ainsi à l'utilisateur de toucher une zone particulière avec un niveau dynamique désiré. Grâce à l'invention, un utilisateur peut jouer du piano, y compris au moyen d'un dispositif mobile de petite taille, comme s'il jouait réellement du piano.
