With the development of the Internet + era, the education model has also undergone tremendous changes. Network information technology is widely used in the contemporary education system, and major colleges and universities have successively launched live online classes. The integration of new technologies has undoubtedly injected new vitality into traditional classroom teaching. Through the webcast class, one-to-many real-time interactive teaching is realized, which brings a lot of convenience to our current teaching. But at the same time, due to the initial application and contact with this teaching method, there are also many problems that need to be solved in the teaching process.

1. Problems with live online classes

1. In the webcast class, the teacher explains the content of the classroom knowledge in the form of webcast. However, due to the limitations of the mouse, the content of the annotations and writing on the blackboard often cannot keep up with the speed of the explanation, and the handwriting is relatively scribbled and poor. During the whole live broadcast class, the teacher cannot flexibly explain the content on the floor, and the teaching experience is not strong, which affects the overall teaching quality.

2. The teaching form is tedious, and the students' sense of participation is not strong.

In the traditional teaching classroom, the teacher can be very passionate when facing the students in the audience, but in live teaching, the teacher only faces one screen, and the teaching form is tedious. In this way, the quality of teaching is weakened, which is harmful to students. Teachers' lectures are no longer lively and interesting, students can't concentrate, and they are less and less interested in live classes, which ultimately affects the overall teaching effect.

2. Feasible solution to the problem of live webcasting

For teachers and students who are accustomed to traditional classroom teaching, the biggest problem is how to realize online blackboard writing and classroom interaction. During the live online class, although the teacher can use the mouse to annotate the content of the courseware, the writing process is very laborious and the handwriting is ugly. Therefore, a hardware device that supports handwriting input recognition is an urgently needed teaching tool for webcast classes.
