Abstract

L'invention concerne un dispositif qui comprend un écran tactile et un capteur, conçu pour détecter une force résultant de l'enfoncement de l'écran tactile. Le capteur comprend un dispositif optique qui reçoit une réflexion d'un signal optique, ladite force agissant sur la réflexion. La réflexion peut être une réflexion d'un motif sur une surface de l'écran tactile, ladite force agissant sur la réflexion.
