Different from traditional whiteboards, digital whiteboards can realize the functions such as touch, writing with finger or pen, and gesture recognition. For example, our IQBoard can support up to 16 points touch, built-in teaching software for facilitating teaching, and 18 hotkeys to make the operation more convenient.. 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.
