The "stamp rally" is an event that participants go the round with predetermined points for the purpose of collecting stamps. They bring a stamp card to these points. They, however, sometimes leave or lose their card. In this case, they do not reach the final destination of the stamp rally. The purpose of this research is the construction of the stamp rally system which distinguishes each participant with his or her hand instead of the stamp card. We have realized our method recognizing a hand posture by the image processing. We have made a simple experiment to confirm the accuracy of our recognizing method by 30 examinees. We have also evaluated accuracy by 7 examinees with the prototype system developed based on the system design.
