Title
(DE) INTERAKTIVES DRUCKPOSITIONSKODIERTES MUSTER-WHITEBOARD
(EN) INTERACTIVE PRINTED POSITION CODED PATTERN WHITEBOARD
(FR) TABLEAU BLANC INTERACTIF COMPRENANT UN SCHÉMA IMPRIMÉ AVEC ENCODAGE DE LA POSITION
Abstract
(EN)
An interactive display system comprising a position coded pattern that is printed on a display surface. An electronic pen is equipped with a decoding real-time processor; the decoding of the surface pattern reveal sets of predetermined (x, y) coordinates embedded within the pattern. A real-time processor works simultaneously to decode (x, y) coordinates while these are sent immediately via wireless communication to a host PC which is normally attached to a projecting device.

(FR)
L'invention concerne un système d'affichage interactif comprenant un schéma codé en position imprimé sur la surface de l'affichage. Un crayon électronique est équipé d'un processeur de décodage en temps réel. Le décodage du schéma imprimé sur la surface indique des jeux de coordonnées prédéterminées (x, y) incluses dans le schéma. Un processeur en temps réel travaille simultanément pour décoder les coordonnées (x, y), celles-ci étant transmises immédiatement par communication sans fil à un ordinateur hôte qui est normalement raccordé à un dispositif de projection.
