PROBLEM TO BE SOLVED: To enhance a possibility of recognition of presence of an object in an area even if a detection means assumed to detect presence of the object in the area differs from a detection means for actually detecting presence of the object in the area.SOLUTION: Detection signals from sensors S-Sare examined by allowing a subject to shade areas (1,1)-(3,3) on a game board with his or her hand, and the number of subjects who have shaded the respective areas with their hands is allowed to correspond to the sections (1,1)-(3,3) for patterns regarding whether the detection signals from the respective sensors in the columns S-Shave been on. Further, in a determination setting column, an area where the number of subjects is larger than a reference is set as an area to be identified for the patterns in the columns S-S. Then, a correspondence between the columns S-Sand the determination setting column is stored as area identification information. When receiving detection signals from the sensors, a lamp control CPU determines an area where objects exist, based on the area identification information. |
