benefits of an interactive whiteboard in the classroom. WHY CHOOSE IT OVER A COMPETITOR??Avocor product development is built upon end user feedback, and this is telling in the features available on the new E series. This feedback has led to our product being different by design, such as the Windows 10 optimisation, best-in-class touch technology, unique object recognition, guest input access and connectivity options to complement existing devices for classroom activities.. 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.
