摘要

Infrared light emitting diode 11 emits infrared light intermittently. It is retroreflected by retroreflective sheeting of the operation article 4 3-N, the infrared light is input to the image sensor 21. Generating a difference image between the image unlit image lit, by analyzing the difference image, MCU23 detects the motion of the operation article 3-N, the image sensor 21 to the terminal (trigger, position, area) of the detection result I want to send to 5. In addition to reflecting the online game process the detection result received, 5-N terminal to the host computer 31. In addition to reflecting the detection processing result received, the host computer 31 transmits to the 5-N other terminals. 5-N terminals of the other reflects the online game process the detection result received.
