A Walk-Rally Support System Using Two-Dimensional Codes and Mobilephones

摘要

"Walk-Rally" (WR), an orienteering-like recreation game, is common especially in Japan. Plenty of trials to combine WR and educational activity are shown by some educators. We developed a WR support system based on the mobilephones having a function of two-dimensional (2D) code reader. Our system can be adapted to both of following two cases: 1) WR Participants read 2D codes placed at each check points with their mobilephones. 2) Human checkers having a mobilephone at each check points read a 2D code which is printed on each WR participant's ID tag. We tested our system with two events whose populations were 100-600. During these events our system had been working successfully.
