Abstract
The infrared light emitting diodes 11 intermittently emit infrared light. The infrared light are retroreflected by the retroreflection sheet 4 of the operation article 3-N, and it is input into the image sensor 21. The image sensor 21 generates the differential image between the image of the emitting period and the image of the non-emitting period. And the MCU 23 analyzes the differential image and detects the movement of the operation article 3-N and transmits the detection result (the trigger, the position, the area) to the terminal 5. The terminal 5-N uses the detection result received for the online game processing and transmits it to host computer 31.
