IR white board

IR white board

Adopting LED light technology, infrared-emitting diode embedded in one side of the board frame transmits infrared light and received by infrared detection diode in the other parallelled side of the board frame, therefore, the infrared light from horizontal and vertical position forms X, Y coordinates. Any opaque object such as a finger or a pointing device writes on the board surface, the infrared light is blocked so as to achieve the accurate positioning coordinates.
