Iqboard Lt V7

The IQBoard LT V7 is a fully featured interactive teaching and presenting system that can transform any standard whiteboard, flat surface (such as a wall), plasma or LCD screen into an interactive whiteboard or touch board. It is a perfect solution for converting traditional classrooms or meeting rooms to interactive platforms that engaging every present student or audience
Principle:
Interactive whiteboard adopting infrared technology consists of an infrared pen which can emit infrared signal and a CMOS sensor which only allow infrared beam to pass through and filter out other visible light. When pressed to the whiteboard surface, the infrared pen sends out infrared signal. The CMOS sensor detects this signal and tracks the (X, Y) position of infrared pen. This technology may be combined with a hard (usually ceramic on steel) surface, which has long life and erases cleanly.
