Abstract

Procédé de détection du contact d'un objet (7) contre un écran (2) transparent ou translucide, le procédé de détection comprenant : - une étape d'émission de rayons infrarouges dans un premier demi-espace (DE1) d'un premier côté (C1) de l'écran (2) ; puis - une étape de détection par une caméra infrarouge (4) d'une image infrarouge (12), l'image infrarouge (12) étant issue de la réflexion des rayons infrarouges contre ledit objet (7), ledit objet (7) étant positionné du premier côté (C1) de l'écran (2) et la caméra infrarouge (4) étant positionnée d'un deuxième côté (C2) de l'écran (2), opposé au premier côté (C1) de l'écran (2) ; puis - une étape de détection d'un trou à l'intérieur de l'image infrarouge (12).Method of detecting the contact of an object (7) against a transparent or translucent screen (2), the detection method comprising: - a step of emitting infrared rays in a first half-space (DE1) of a first side (C1) of the screen (2); then - a step of detection by an infrared camera (4) of an infrared image (12), the infrared image (12) being derived from the reflection of the infrared rays against said object (7), said object (7) being positioned on the first side (C1) of the screen (2) and the infrared camera (4) being positioned on a second side (C2) of the screen (2), opposite to the first side (C1) of the screen (2); then - a step of detecting a hole inside the infrared image (12).
