Figure 5. Transfer of the displayed contents on the IdeaBoards.
The system can be used not only for one classroom by placing multiple IdeaBoards, but also for remote classrooms where IdeaBoard(s) at each site displays synchronized contents with the other IdeaBoard(s).
This paper has presented two extensions to our interactive electronic whiteboard system named IdeaBoard. One extension is to separate the control information from the contents of the board so that students are not bothered by the control information. Preliminary evaluation has shown that hiding control enables the audience to focus their attention on the contents, although it may prevent them from predicting what is going to happen. The second extension is to connect multiple electronic whiteboards. This allows us to realize a computerized surface as large as real blackboards. Moreover, it may provide collaborative usage between remote sites. More rigorous evaluation remains to be done.
