Our product is new with high technology.  It is based on the general projector with more advanced features. It dosen't need to stick any pare part on the wall or board surface but only need a small A-frame mount. It support  touching and laser remote writing, drawing, control, etc. At the same time, its weight and volume is much smaller than the traditional whiteboards. We have our own manufacturers to keep the competitive price. As far as I know that this new Interactive Whiteboard is very popular among worldwide customers. I believe it will have a bright future in the IWB field in future.
