Recently, a lesson "Virtual Reality Production" lectured by Ni Dong from the School of Visual Art was broadcast on the Bilibili live broadcast platform, attracting 1,865 "students" to watch online, which was reported by the Sanxiang City News.
Ni Dong started with people’s feeling of alienation caused by the isolation from their families during the epidemic, inspiring "students" through learning, creativity, design and production to combine the virtual reality technology and art in the course to break the psychological distance brought by physical isolation to people. It helps to realize the emotional appeal of people in this special period and to narrow and harmonize the emotional exchange between people. From the virtual reality, augmented reality, to mixed reality, he did the explanation and demonstration step by step, which benefited "students" to a great extent.
This "Virtual Reality Production" course is the first live broadcast of the network theory teaching work in HNMMC. It has formed 208 episodes of granular micro-classes, with more than 5,600 students selected.
It has been broadcast for more than 40 times so far, with an average online viewing and learning volume of 2000 people around at the same time inside and outside school and in the industry. The peak reached about 3,000 people, pushing the course to the top of the list by the live broadcast website with the online course views exceeding one million. It was kindly praised by students as a breath of fresh air in the live broadcast industry. Although the conditions at home during the epidemic were limited, Mr. Ni studied hard, using simple props and equipment to conduct a high-tech information teaching method. Utilizing the model of virtual studio in combination with real-time image matting technique, he naturally integrated the real image of the teacher into the virtual teaching environment, bringing students a visual enjoyment like watching a blockbuster, and stimulating their interest in study while having the sense of immersion and interaction in the real-time classroom.
At the same time, catering to the interests and hobbies of the new generation of students and preventing them from having a dull visual fatigue, Mr. Ni created a virtual character capture technology, integrating the teacher and virtual animation character, which could be replaced in real time. With the help of an ordinary camera, the application of expression capture technology and body and limb capture technology made the teaching by a virtual character real. Using students’ favorite cartoon image to assist the teaching brought the freshness to students and stimulated their interests in study. Some students joked that they used to be late for classes but now they watch it on time without missing any classes. It can not only attract the attention of students, but also strengthen the love and desire for knowledge.
Live broadcast of teaching brought a new demand and challenge to the real-time analysis and mastery of the studying situation so as to dynamically adjust the teaching focus and difficulties. Mr. Ni then took informatization methods to study and tried to use the online discussion wall to encourage students to express their perception of the course and inspire creative thinking. What’s more, it guided students to create a design thinking that integrated with the current epidemic to effectively help people’s life and prevent the epidemic, which stimulated their great interest in discussion and enthusiasm for participating in live broadcast courses. Meanwhile, it offered an interesting self-assessment method, encouraging students to bravely and truly evaluate the effect of distance self-study, which could be used as a scientific basis for teachers to adjust the content of live courses, solve teaching priorities, and difficult problems. It enabled to meet students’ creative ideas in real time and be more aligned with students’ interests, solving students’ problems and confusions specifically, actively helping students to eliminate obstacles in learning, and playing a positive role in building their confidence to overcome difficulties. Students have shown unprecedented enthusiasm for cooperation in this form of informational interaction. Through a more comprehensive analysis of study conditions, the efficiency of remote live teaching has been greatly improved.
