Abstract

L'invention concerne un dispositif d'affichage d'images tactile, le dispositif comprenant : un projecteur d'images pour projeter une image affichée sur une surface ; un système optique à capteur tactile pour projeter de la lumière définissant une pellicule tactile au-dessus de ladite image affichée ; une caméra destinée à capturer une image de détection tactile provenant d'une région comprenant au moins une partie de ladite pellicule tactile, ladite image de détection tactile comprenant la lumière diffusée à partir de ladite pellicule tactile par un objet s'approchant de ladite image affichée ; et un processeur de signal couplé à ladite caméra pour traiter une image de détection tactile provenant de la caméra pour identifier un emplacement dudit objet par rapport à ladite image affichée ; ledit objet étant pourvu d'un élément rétro-réfléchissant pour réfléchir la lumière provenant de ladite pellicule tactile.
