1 Introduction
Thank you for selecting our infrared interactive whiteboard and software!
1.1 Infrared technology principle
A plane scanning surface is formed by the infrared receiver and transmitters on x-axes and y-axes located
inside the frame. When an object enters the scanning surface and stops the scanning on that point, the
point’s coordinate(x, y) is found by sensing the blocked infrared beams from horizontal and vertical
directions.
