Adopting Wireless Electromagnetic Induction technology, LABWE Electromagnetic Blackboard is an input device providing strong interaction potential between Human and Computer, Man and Software, E-Blackboard software and other software applications. Connected the E-Blackboard to PC, the E-Blackboard screen can synchronously display content on PC screen. In the mean time, the computer can be manipulated by Electromagnetic stylus operating on the E-Blackboard screen instead of Mouse connected to the PC (enabling Left & Right Click functions). LABWE Electromagnetic Blackboard has surpassed traditional one-way operation of projection equipment system and achieved great breakthrough in terms of interaction. A complete set of E-Blackboard system should include the following parts: 1.Electromagnetic E-Blackboard 2.Electromagnetic Stylus 3.Personal Computer 4.Projector 5.LABWE Electromagnetic Blackboard Software Electromagnetic Blackboard can detect the movement of the Electromagnetic stylus and the information can be transmitted to a PC which connected to it. E-Blackboard application software installed on the PC converts the movement information of the electromagnetic stylus into the computer's screen coordinates, and the results are projected onto the E-Blackboard by projector. This constitutes a complete interactive demonstration system. Wooden carton
