72"Dual Users Writing Interactive Whiteboard

Work principle:
An IR IWB is surrounded by infrared receiving tubes and infrared emission tubes which are in one-to-one relationship on the surface of IWB and form into an invisible infrared network. "When an object comes into the infrared network, it will weaken receiving signal in both transverse and vertical direction. The equipment positions the touch point through receiving signal's fluctuation. Only a pair of infrared tubes (one emission tube and one receiving tube correspondingly in physical position) can process data when IR IWB works. The circuit can achieve rapid response through the high-frequency data collection from this special pair of infrared tubes.
