Problems solved by technology

[0002] Today, when the society is becoming informatized and intelligent, the development of educational informatization is still relatively lagging behind. Its corresponding products include the initial multimedia to the current electronic whiteboard, recording and broadcasting classrooms, etc. Among them, multimedia equipment can only be used on computers. The operation can not be directly operated on the multimedia screen, and the interaction is very lacking. Without high-quality presentations, it is easy to cause the class process to be boring and the students' learning efficiency to be relatively low.
The electronic interactive whiteboard developed in recent years has largely improved this problem, but the electronic whiteboard also has high cost, unstable quality, and low actual utilization rate. Based on the current situation of unbalanced educational resources, Difficult to popularize and promote
