(EN) METHOD AND SYSTEM FOR PROVIDING INTERACTIVE VIRTUAL TABLECLOTH
(FR) procédé et système pour obtenir une nappe virtuelle interactive
Abrégé
(EN)
A method and system for providing an interactive virtual tablecloth. A server transmits various types of content, and a projector projects images corresponding to the transmitted content onto a display surface. For example, the display surface can be a table. The server receives control signals from at least one wireless client device, and adjusts the content based on the control signals. When a plurality of users share a common display surface, such as restaurant customers at a table, the display surface is divided into windows for each of the users. Each user can use a wireless client device to control his/her own window.
(FR)
L'invention concerne un procédé et un système pour obtenir une nappe virtuelle interactive. Un serveur transmet divers types de contenus, et un projecteur projette des images correspondant aux contenus transmis sur une surface d'affichage. Par exemple, la surface d'affichage peut être une table. Le serveur reçoit des signaux de commande provenant d'au moins un dispositif client sans fil, et règle les contenus sur la base des signaux de commande. Lorsqu'une pluralité d'utilisateurs partage une surface d'affichage commune, telle que des clients d'un restaurant à une table, la surface d'affichage est divisée en fenêtres pour chacun des utilisateurs. Chaque utilisateur peut utiliser un dispositif client sans fil pour commander sa propre fenêtre virtuelle.
