<p><P>PROBLEM TO BE SOLVED: To easily discriminate a terminal from which annotation is performed, by selectively displaying only an object drawn on a designated layer. <P>SOLUTION: An electronic drawing device includes: a display means 1 connected with a plurality of information terminals for displaying a shared screen thereon; a layer display control means 7 for displaying a selected layer while superimposing it on the shared screen; a layer information storage means 4 for storing a corresponding layer for each information terminal and information about the layer; and a layer information distributing means 6 for managing the layer information stored in the layer information storage means and for distributing layer information being managed when there is a layer information acquisition request from an information terminal. In such a configuration, only a drawing object drawn on a designated layer is selectively displayed, thereby easily discriminating a terminal from which annotation is performed. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
