Introduction

Since computer literacy education has commenced in schools, the number of personal computers installed at each school is increasing. However, the way in which students use the computer seems to have some intrinsic problems. The students get absorbed in their own matter and do not concentrate on what their teacher is saying. Moreover, it is difficult for the teacher to see the students' faces because they are hidden by displays. Although information processing is available at hand, a PC for each student may destroy the interactive and collaborative relation between the teacher and the students which has been inherent in a class room with a blackboard where the teacher can focus the students' attention on her/his writing on the blackboard.

Although, exercises and self-study with the computer are indispensable for the students to learn for themselves at their own pace, the necessity of combining the information processing power of the computer with the potential advantages of the blackboard is not lessened.

We have made an interactive electronic whiteboard system named "IdeaBoard" (interactive, dynamic, electronic assistant board) similar to Liveboard ( Elord et al. 1992), and developed new human interaction techniques suitable for a large surface with an electronic marker as well as some educational applications which exploit the system ( Nakagawa et al. 1997).

This paper presents two extensions to the IdeaBoard. One extension is to separate the control information from the contents of the board. The second extension is to connect multiple boards.
