Abstract (in Japanese) (See Japanese page) 
(in English) We developed a device named Sounding Board that enables mutual and instant assessment during an activity. We performed an experiment in an elementary school, whose students were able to operate the handheld device without difficulty. However, some technical problems are yet to be resolved, e.g., the trade-off between the viewing and IR receiving angles and the occlusion caused by hand. This problem occurred because the tilt angles to capture IR signals and to look at the screen of the handheld device were different.
In order to solve this problem, we developed a device which can detect tilt angle when a user use a PDA and did some experiment to find suitable angle for pointing some targets displayed on the screen. This experiment revealed to us that average tilt angle is 30 deg.
