Moreover, the interactive projector can project the screen onto the curtain, whiteboard or even directly onto the wall. As long as you want, any plane can interact without any restrictions. From now on, the teacher will no longer be confined to the podium, he / she can move around in the room at will, and can also pass the "pen" to someone behind the room to enable it to interact with the projected content. More importantly, this interaction is not limited to the teacher and the teaching content, but also exists in the arbitrary interaction between the teacher, the student, and the teaching content.

Gradually developed.
