Educational Interactive Whiteboard
Infrared interactive whiteboard
HT series infrared interactive whiteboard adopts infrared induction technology, which use corresponding IR emitting tube and receiving tube, to form a layer of invisable grid matrix. IR that sent from LED electric wave will be cutted off when any touch to the surface and signal vanish accordingly, then the detected X, Y coordinates position information will be sent to computer via main control board, Infrared interactive whiteboard is available for use in tough environment, any non-transparent object can alter the infrared contacter to accomplish screen touching operation.

Electromagentic interactive whiteboard
HT series electromagnetic interactive whiteboard adopts a pen which can emit electromagnetic waves to the board, it is composed of horizontal and vertical arranged receiving coil films that in a same size with display area. Pen emits the electromagnetism intermittently, and coil inducts the most electromotive force when the pen closing to it, then the positions of the X, Y coordinate can be figured out accordingly.
