Abstract

Un appareil (10) permettant la communication visuelle comporte un écran (12) pourvu d'une surface de projection (14) que l'on peut faire alterner au choix entre un état transmissif (16) et un état diffus. A l'état transmissif (16), une caméra (28) placée derrière l'écran (12) enregistre l'image d'un utilisateur (26) de l'autre côté de l'écran (12). A l'état diffus (18), un projecteur (30), également placé derrière l'écran (12), projette une image (20) sur la surface de projection (14). L'appareil (10) peut être disposé soit sous forme de poste unique pour permettre une communication visuelle au profit d'utilisateurs (26) en un seul endroit, soit sous forme de deux postes séparés positionnés en des endroits éloignés pour permettre une communication visuelle bidirectionnelle entre des utilisateurs (26, 126) positionnés à chaque poste. Le positionnement et la synchronisation de la caméra (28) et du projecteur (30) permettent un contact visuel face à face entre les utilisateurs (26, 126).
