Working principle of interactive electronic whiteboard

The working principle of the infrared touch screen is to cover the infrared receiving tube and the infrared transmitting tube around the touch screen. These infrared tubes are arranged in corresponding position relationships on the surface of the touch screen to form a light network composed of infrared rays. When an object (it can be a finger, a gloved hand or any touching object) enters the infrared light network and blocks the infrared emission and reception somewhere, this point receives infrared rays horizontally and vertically.
