Abstract

L'invention concerne un système et un procédé de mise à jour d'un message affiché sur un écran électronique par l'intermédiaire d'un dispositif de communication sans fil ou d'un site Web distant. Des messages sont entrés dans le dispositif de communication (terminal d'entrée) ou sur une interface Web par le biais de commandes vocales ou de la saisie d'un texte. L'entrée est ensuite transmise à un ou plusieurs écrans électroniques, où le message est affiché. Ainsi, les utilisateurs peuvent mettre à jour un affichage électronique sans manipuler directement l'écran d'affichage. Chaque écran électronique peut communiquer sans fil sur des réseaux cellulaires et via des connexions Bluetooth. Grâce à ces procédés de connexion, plusieurs écrans électroniques peuvent être appariés à un seul dispositif de communication sans fil, et plusieurs dispositifs de communication peuvent manipuler n'importe quel écran donné directement ou par l'intermédiaire d'une interface Web.
