1.Product Description Interactive whiteboard PS is a new teaching and demonstrating tool adopting electromagnetic induction technology.It is used to emit electromagnetic wave of a pen and the board surface is composed by the receiving coil membrane in both directions by the horizontal and vertical array. The membrane size is the same with the display area.Electromagnetic pen intermittently emits electromagnetic wave. When the pen is near the membrane of the receiving coil, the coil will be induced to the electromagnetic launchers. According to the horizontal direction and vertical direction of the force sensor, the pens location of X, Y coordinates can be found by calculating.
