Abstract

La présente invention concerne un dispositif d'entrée pour la détection multidimensionnelle, qui permet de mesurer successivement ou en parallèle plusieurs valeurs de pression à de multiples emplacements grâce à la mesure de valeurs de pression ultérieures résultant du déplacement d'éléments du dispositif d'entrée, sans avoir à déplacer le dispositif d'entrée lui-même. Selon un mode de réalisation préféré, la présente invention se rapporte à un dispositif d'entrée à réseau de tiges en association avec une feuille conductrice sensible à la pression et avec des éléments élastiques, qui est conçu pour commander en temps réel un appareil, tel qu'un instrument de musique.
