A position of a cursor 67 is controlled so that positions of retroreflective sheets 17L and 17R in real space coincides with positions of cursors 67 in a video image projected onto a screen 21, on the screen 21 in the real space. A processor 23 can recognize positions of the retroreflective sheets 17 on the video image via the cursors 67. Hence, the player 15 can perform input to the processor 23 by moving the retroreflective sheets 17L and 17R on the video image projected onto the screen 21 and indicating directly desired locations on the video image by the retroreflective sheets 17L and 17R.
