Abstract

L'invention concerne un procédé, un dispositif et un système d'utilisation de tableau blanc, un dispositif de type tableau blanc et un support de stockage, qui sont appliqués au domaine des dispositifs de type tableau blanc. Le procédé consiste à : détecter un événement d'utilisation qui se produit au niveau d'un premier tableau blanc ; si une cible de l'événement d'utilisation est un élément de page, demander un verrouillage d'élément de l'élément cible ; et après la demande du verrouillage d'élément de l'élément cible, afficher un résultat d'une utilisation pour l'élément cible sur le premier tableau blanc, l'élément cible étant un élément de page vers lequel est dirigé l'événement d'utilisation et l'élément cible n'appartenant pas à des éléments de page actuellement en cours d'utilisation d'un événement d'utilisation d'un deuxième tableau blanc. Le premier tableau blanc et le deuxième tableau blanc appartiennent à la même réunion partagée, et les pages affichées sur le premier tableau blanc et le deuxième tableau blanc sont les mêmes, ce qui permet d'obtenir l'effet d'une pluralité d'utilisateurs qui utilisent simultanément le tableau blanc au niveau de multiples terminaux de tableau blanc qui participent à la réunion partagée. Les modes de réalisation de la présente invention résolvent le problème de faible efficacité lorsque de multiples personnes utilisent un tableau blanc dans une réunion partagée, et évitent les conflits de fonctionnement lorsque de multiples personnes utilisent le tableau blanc.
