The students can only look at the big screen, judge the teacher's explanation position through the arrows on the screen, and listen to the teacher's explanation. In this case, the image of the teacher is not in the students' field of vision, the eyes of the teacher and the students cannot meet, the teacher's body language cannot be displayed, and the teacher becomes the "narrator" of the multimedia presentation screen. If the teacher stands in front of the big screen to explain, although the above problems can be solved, but because of the need to switch the display screen from time to time, for example, when demonstrating a PPT document, in this way, he has to go to the teaching computer to operate the computer from time to time, which brings a lot of problems to teaching. A lot of inconvenience.

Although there are already some multimedia teaching demonstration devices that can be remotely and wirelessly controlled, the teacher can control the teaching computer through the controller in his hand, and the wireless communication between the controller and the teaching computer, so that the teacher does not have to stay by the computer all the time. Activities can be performed throughout the teaching area. But at present, this kind of controller can only perform simple functions such as PPT page turning. If the lecturer wants to make some notes on the document, he still needs to go back to the teaching computer and operate on the computer. In addition, when teaching, when the teaching space is large and there are many people, the teacher often needs to prepare amplifying equipment such as microphones, which also causes cumbersome teaching equipment and inconvenience in use.
