Abstract

L'invention concerne un écran tactile dans lequel un retour de force horizontal fourni à l'utilisateur, et un moyen d'entrée utilisant l'écran tactile autre qu'une pression peuvent être mis en œuvre au moyen d'un composant unique. Un mécanisme d'amplification du déplacement à levier composite est disposé sur les côtés de l'écran tactile et joue simultanément le rôle d'une source de détection et d'une source d'entraînement. Cela permet non seulement de fournir une sortie vibratoire simple, mais également de délivrer des ondes progressives par l'intermédiaire des positions de toucher. En utilisant un mécanisme d'amplification du déplacement pour détecter le mouvement de l'écran tactile lui-même, il est également possible de saisir une entrée en déplaçant l'ensemble du panneau tactile lui-même.
