A background
With the rapid development of science and technology and the maturity of virtual technology, after multimedia, a new type of teaching media has emerged in the field of teaching technology. It is a virtual studio system. Its application in the education system has caused a new teaching model. The revolution made us get rid of the constraints of traditional space environment, space distance and factual objects, and enter an infinite imagination space, enriching the teaching content with various novel and peculiar creativity. The rapid development of education informatization, the expansion of enrollment and development of colleges and universities, and the continuous extension of network and distance education have enabled more and more schools to use virtual studios to achieve multimedia, network, and satellite distance education through more communication channels. School image, publicize school culture, reflect the school's comprehensive strength, and expand academic influence.
Comrade Jiang Zemin profoundly pointed out at the conference to commemorate the 100th anniversary of the establishment of Peking University: "Science and technology are advancing by leaps and bounds, the knowledge economy has seen signs, and national power competition is becoming increasingly fierce." From the perspective of the general trend of world economic development, in the face of the rapid development of modern economy, the development of education in China has lagged behind, and we must further adapt to economic development and strengthen advance awareness. This is a major prerequisite for building a virtual studio system and is also a routine Further improvement and development of teaching methods.
Second application in teaching
The application of virtual studio system in teaching has fundamentally improved the limitations of traditional studio recording courses. It solves the problems of expensive traditional studios, lack of realism in recorded courses, and boring teaching mode.
Virtual studios mostly require fixed scenes in teaching videos such as lectures, experiments, operations, and demonstrations, and the scope is not large. Basically, they can be accommodated in multimedia classrooms. It is very suitable for virtual studios. Through the virtual system and material library, the investment in real manpower, material resources and financial resources is greatly reduced.
Many difficulties in the production of teaching video programs, such as abstract scientific principles, (such as buoyancy knowledge is the key and difficult content in physics, when using traditional teaching media to reveal the causes of buoyancy, Archimedes principle and other difficult content , By analyzing the pressure of the liquid on the six surfaces of a cube immersed in water, it is concluded that the buoyancy is equal to the difference between the upward and downward pressures on the object. The relationship between the pressure of the liquid and the depth is used in the analysis. Knowledge such as force balance involves more power, and students feel very abstract in their understanding, and it is not easy to form the correct concept in the brain. The virtual studio system can provide some situations that students cannot experience in reality, and use them to conduct experiments on their own. Students adjust the parameters through human-computer interaction, explore the physical state under different parameter states, and obtain relevant real-time data, so that some invisible factors in physics and their changing laws are presented to the students, so as to discover and summarize some laws. Turning invisible into tangible and abstract into image, breaking through the difficulties and making it easier for students to understand ) Macrocosm and microcosm, and so on, are very suitable for animation and other virtual reality approach to the performance, and virtual studio technology itself is a graphical workstation-based, there are inherent advantages in the performance of virtual reality. Only in this way can we learn to take the initiative, exert imagination and originality, and it is more suitable for students to understand memory.
Virtual studio technology In distance education, how to combine multimedia courseware and video has always been a problem people try to solve. In a virtual studio, the producer can use the virtual electronic background to combine the computer multimedia courseware with the video image of the presenter. Teaching needs to be synthesized or switched at will to achieve the best teaching effect.
Since the electronic background of the virtual studio is generated by a computer, if the position information and video data are transmitted together, the distance education can be interacted by setting the feedback area of ​​the image, and a humanized learning environment can be created to make the remote Teaching students can learn in a natural and friendly atmosphere in order to stimulate students' interest in learning and understand memory.
Make up for the lack of distance teaching conditions. In distance teaching, some teaching experiments that should be set up cannot be carried out due to reasons such as experimental equipment, experimental site, and teaching expenses. Using the virtual studio system can make up for these shortcomings, students can do a variety of experiments without leaving home, get the same experience as the real experiment, so as to enrich the perceptual knowledge and deepen the understanding of the teaching content.
For the school, having a good virtual studio can not only increase the enrollment rate, improve the teaching quality, shape the school image, but also lay a solid foundation for the school to train a variety of artistic talents.
The world today has entered the information age, and colleges and universities are vigorously developing their own information technology, information communication facilities, and information industry. The virtual studio provides a new way for education, teaching and scientific research.
In traditional teaching activities, teachers impart knowledge to students through explanations, demonstrations, student group experiments, etc. Due to the limitations of students ’thinking development, teachers must use many image languages ​​to describe, and teachers’ presentations are sometimes subject to objective conditions. Limitations, the effect is not obvious enough, the application of information technology can break through the limitations of time and space and the difficulty of language description, visually display materials, reproduce the experiments made by previous people, and students can gain an understanding of the phenomenon by observing the experiments. For example, the relationship between the rotation direction of the coil in the generator, the direction of the magnetic induction line and the direction of the induced current in the coil, the effect of the explanation and the wall chart is not intuitive and vivid without the multimedia courseware animation effect combined with the virtual studio system.
Teaching work should be efficiency-oriented. According to the current trend of teaching reform, it is more difficult for students to learn more knowledge without relying on excessive schoolwork burden. It is more difficult to rely on textbooks, blackboards, and chalk. After using the virtual studio system, you can fully mobilize the students' various sensory organs to achieve the effect that the whole is greater than the sum of the parts. The video display produced by the virtual studio system can increase the opportunities for students to practice, thereby mobilizing the students 'enthusiasm for learning, increasing the students' activity time, thereby achieving the purpose of increasing the capacity of the class and improving the classroom teaching effect.
All kinds of teaching resources, various teaching elements and teaching links are integrated with each other to achieve overall optimization. The courseware interactively produced by the virtual studio system can not only simulate various experiments and demonstrate the scenarios and processes of material changes, but also reproduce the derivation process of theorems, laws and laws. For some physical processes that are difficult to describe clearly in language, simulate and reproduce with a virtual studio system, which saves a lot of teachers ’oral time. This information is very expressive, saves a lot of time on blackboard and drawing, and keeps students learning. The continuity of thinking in the middle, at the same time arouse students' eyes, ears, mouth, hands, brain and other senses, prompt students to take the initiative to remember, think hard, explore hard, and actively participate in teaching. The main role of students can be brought into full play, learning is easy and lively, enjoyable, and they can learn and master new knowledge quickly. The courseware produced by the virtual studio system is not only used in classroom teaching, but also plays a role in self-study tutoring for students after class, so that the 45 minutes of the classroom have enough extension and optimize the teaching process.
Modern students are more lively, they are particularly interested in new things, and they are very concerned about the development of the society. Traditional education media sometimes cannot meet the urgent requirements of students. Multimedia education technology under the virtual studio system can be very good. To meet the requirements of students, you can use the obtained information for teaching in a timely manner, use information technology to display the achievements of modern science and technology, expand students' horizons, and use information technology for ideological and aesthetic education in teaching.
Introducing the technology of virtual studio system into teaching can not only make teaching methods more abundant and vivid, but also promote the diversification of teaching organization forms and teaching methods, and can promote the diversification of information exchange in the teaching process and the diversification of cognitive methods. , And ultimately achieve the diversification of teaching objectives.

Five conclusions
To develop virtual studio technology, virtual studios must handle policies and markets, serve learning and services, current interests and long-term interests, market operations and school systems, with the popularization of educational information, the exchange of teaching information in various places, and the learning resources Sharing, showing the image of a school, it is imperative for the school to build a virtual studio system. In teaching, the virtual studio is used to assist teaching, increase student interest, and play a very good role in increasing school awareness, school advertising, And lay the foundation for school recruitment and employment.
Virtual studios are just one of the contents of school informatization, but we still emphasize it so much because there are a lot of abstract scientific principles in teaching. The macro and micro worlds are very suitable for virtual studios to achieve, enabling students to be vivid Intuitively understand the principles. Through the virtual studio, we discovered the problems that previously troubled our students, the unacceptable knowledge, and solved it. Its unique and powerful functions are worthy of course developers, teaching staff and institutions, and even the entire society. The attention and research on the above core issues do not let the campus virtual studio stay in the ideal.
Note: This virtual studio design principle and technical difficulty analysis mainly refer to Beijing Xinchuang Jiahe Digital Video Co., Ltd. UCX-3D series campus true three-dimensional virtual studio system.
