A complete set of LABWE (Infrared) E-Blackboard system should include the following parts: Infrared Induction Electronic Blackboard, Normal Pen, PC, Projector and LABWE Electronic Blackboard Software. The Infrared Induction Electronic Blackboard can detect the movement of normal pen on its surface and the information can be transmitted to a PC which connected to it. LABWE E-Blackboard software application installed on the PC converts the movement information of the normal pen into the computer's screen coordinates, and the results are projected onto the Infrared Induction E-Blackboard by projector. This constitutes a complete interactive demonstration system. Users can operate with any opaque object on the Infrared E-Blackboard screen so as to manipulate the computer and to edit, modify, annotate, draw geometric figures, print, save, etc., simulating efficiently the Mouse and Keyboard. LABWE (Infrared) Electronic Blackboard can be widely used in classroom teaching, training, conferences, presentations, distance learning and many other areas. Wooden carton
