摘要

The positions of cursors (67) are adjusted such that on a screen (21) in a real space, the positions of retroreflective sheets (17L, 17R) in the real space and the positions of the cursors (67) in a video image projected on the screen (21) match. A processor (23) can recognize the positions in the video image where the retroreflective sheets (17) are placed via the cursors (67). Therefore, a player (15) can make input to the processor (23) by moving the retroreflective sheets (17L, 17R) on the video image projected on the screen (21) to directly indicate desired positions in the video image by the retroreflective sheets (17L, 17R).
