Description

technical field [0001] The present invention relates to an electronic whiteboard and a system using the electronic whiteboard, more specifically, to an electromagnetic induction interactive electronic whiteboard and a system using the electronic whiteboard. Background technique [0002] With the development of electronic technology, electronic whiteboards have appeared in recent years. For example, Chinese patent ZL02257337.2 with an application date of September 16, 2002 discloses a "electronic whiteboard with a built-in wire grid electromagnetic induction layer". This electronic whiteboard includes an input part, a frame and a control circuit. The input part includes a writing layer, a bottom support layer and an input sensing layer between the two layers. The output of the input sensing layer is connected to the control circuit. The input sensing layer is composed of a wire It is wound along the X and Y axes respectively to form a staggered warp and latitude network, whic...
