4x6 whiteboard. The working principle of the electromagnetic induction type is: electromagnetic waves can be propagated through air and insulating objects. The electromagnetic induction type is composed of a receiving coil film that can emit electromagnetic waves in two directions, horizontal and vertical, and the size and display area of ??the film. the same. The principle of positioning is that the pen that emits electromagnetic waves emits electromagnetic waves in an intermittent manner. When the pen is close to the film of the receiving coil, the electromagnetic waves emitted by the pen are sensed on the coil. The higher the electromotive force induced by the coil group closest to the pen, the X and Y coordinate positions where the pen is located can be calculated by the electromotive force induced by the horizontal direction and the vertical direction .

The IQAio GR519 is an upgraded lightweight version based on the original IQAio GR511. The original dual-cavity structure was changed to a bottom-edge structure, so that the minimalist design accommodates modern classrooms and conference rooms. With one IQProjector V2 and one IQView E3821, you can achieve flexible and intelligent classroom.
