The presentation execution means executes the presentation by detecting the position or motion of the player with emitted infrared pattern light if the infrared pattern light is not emitted from another game machine set in the periphery when the presentation is started, and executes an alternative presentation which does not require detection of the position or motion of the player without emitting infrared pattern light if emission of the infrared pattern light from the other game machine is detected. <P>COPYRIGHT: (C)2013,JPO&INPIT |
