The invention relates to an interaction arrangement (1) for interaction between at least one display screen (3) disposed behind a transparent pane (2) and at least one pointer object (4) located in front of the pane (2), comprising at least two cameras (6, 7) disposed behind the pane (2), wherein one deflection unit (8, 9) is associated with each of the cameras (6, 7), by means of which deflection units at least one optical path (10.1) may be deflected from an interaction region (11) in the vicinity of and in front of the pane (2) into the camera (6, 7) and one processor unit (12) connected to each of the cameras (6, 7) for detecting a position of the pointer object (4), which is being guided in a visible manner to at least two of the cameras (6, 7), wherein at least the interaction region (11) may be stroboscopically illuminated with infrared light and the cameras (6, 7) are infrared-sensitive and may be synchronized with the stroboscopic illumination.

L'invention concerne un système d'interaction (1) pour assurer une interaction entre au moins un écran (3) disposé derrière une vitre (2) transparente (2) et au moins un objet indicateur (4) situé devant la vitre (2). Ledit système d'interaction comprend au moins deux caméras (6, 7) disposées derrière la vitre (2), une unité de déflexion (8, 9) étant associée à chacune des caméras (6, 7) et servant à dévier au moins une trajectoire de faisceau (10,1), d'une zone d'interaction (11) se trouvant à proximité et devant la vitre (2), dans la caméra (6, 7), ainsi qu'une unité de calcul (12) reliée à chacune des caméras (6, 7), pour déterminer une position de l'objet indicateur (4) guidé de manière visible pour au moins deux des caméras (6,7). Au moins la zone d'interaction (11) peut être éclairée de manière stroboscopique par lumière infrarouge et les caméras (6, 7) sont sensibles aux infrarouges et peuvent être synchronisées avec l'éclairage de type stroboscopique.
