HI Series of Interactive Whiteboard IEBOARD use infrared sensor technology. It use One-to-one infrared emission control and infrared receiver tubes. Slightly above the surface of the whiteboard the projection forms an invisible layer of the matrix cross grid. When touching the surface of the board, the wave from the LED emits in the infrared will be blocked, and then the signal of receiving tube disappeared, after the XY coordinate information is detected its location, through the main transmission to the computer control panel. Infrared interactive whiteboard can be used under harsh environment. Any non-transparent objects can be changed the infrared ray on the contacts to realize the infrared touch screen operation.
