INTECH Portable Interactive Whiteboard is a fully featured interactive whiteboard system that transforms any standard whiteboard, flat surface (such as a wall) or projection screen into an interactive whiteboard.No battery is required for USB signal receiver and the unit can be mounted to the ceiling if a permanent solution is required. Working with the extendable pointer E-Pen(Electronic pen) or stylus E-pen, you and your students can explore internet websites, build interactive flipcharts and creat more opportunities for discussions and interaction in the classroom.
