Virtual reality technology integrates computer graphics technology, computer simulation technology, sensor technology, display technology and other science and technology，It creates a virtual information environment on a multidimensional information space，Enables users to have a sense of immersive，The ability to interact with the environment is perfect，And helps to inspire ideas。Therefore, immersive - interactive - imagination is the three basic characteristics of VR environment system。The core of virtual technology is modeling and simulation。 [1]
Application field
VR has not only been focused on the field of computer images, it has involved a wider range of fields, such as video conferencing, network technology and distributed computing technology, and the development of distributed virtual reality。Virtual reality technology has become an important means of new product design and development。Among them, collaborative virtual reality is a new research and application hotspot of VR technology, it introduces new technical problems, including human factors, network, database technology and so on。Such as human factors, it is necessary to consider how multiple participants interact with each other in a shared space, and the behavior of virtual objects in virtual space under the joint action of multiple participants。In the collaborative design in the VR environment, team members can engage in the construction and operation of virtual objects in the virtual environment synchronously or asynchronously, and can evaluate, discuss and redesign the virtual objects。Distributed virtual environment enables geographically distributed designers to face the same virtual design object. Through the collaborative use of sound and video tools in the shared virtual environment, design defects can be eliminated at the early stage of design, the time to market of products can be reduced, and product quality can be improved。In addition, VR has become an important tool for constructing virtual prototyping and supporting virtual prototyping technology。VE - Virtual environment technology enables engineers to interact with their design prototypes (virtual prototyping) in real time in 3D space。
Industry application
First, real estate roaming: in the virtual reality system to walk freely, arbitrary viewing, strong impact, can enable customers to get the real feeling of immersive, promote the speed of contract signing。
Second, virtual model room: for commercial projects long-term investment, leasing, for all kinds of evaluation activities。One-time investment can be applied in all aspects of project approval, construction, sales, investment and leasing, and can be used permanently。
Third, multi-professional coordination: multi-type vehicle routes and other arrangements, headroom height, such as road and bridge simulation。
Fourth, online house viewing: The users of the rental and sale stage through the Internet immersive understanding of the project's weekly environment, space layout, interior design 。
5. Venue simulation: Show the real venue style in advance, assist design approval, and avoid design investment risks。
Virtual Reality (Virtual Reality, hereinafter referred to as VR) technology can be truly experienced by consumers, but when it comes to the industry level, VR is still there
In the growth period, whether in technology, products, content, norms, are slightly immature。There is no doubt about the VR trend, but for now, the VR market is still only a weak fire。VR "fire" in the industry and geeks two specific groups of people, for the mass consumer, VR is clearly not just needed。
However, people are optimistic about VR, because it is not only a new technology that represents the future, but also a product of the development of the Internet technology industry chain and people's increasing entertainment needs, which is a new thing born with the trend。On the surface, the core value of VR is to take the audiovisual experience to a new level。On a deep level, that could be a big deal。At present, the global VR equipment is mainly based on glasses and helmets, and China's development progress is basically the same, but the scale is small。On a global scale, there are several major problems: first, the wearing experience is not good;Second, lack of content, difficult to meet the needs;Third, the lack of uniform norms。It is important to note here that history has taught us countless times that what we thought would be a problem will not be a problem.

2016 China Dream micro film competition launched VR panoramic micro film has become a new highlight, many people like to use VR glasses to watch movies。
Education: The application of virtual reality technology in the field of education mainly focuses on four aspects: supporting the creation of learning environments, supporting practical skills training, supporting language learning, and supporting the education of special children。
Virtual reality technology can fully mobilize learners' vision, hearing, touch, smell, taste, etc., realize the connection of physical and mental feelings, and enhance learners' sensibility。
The potential of the application of virtual reality technology in the field of education stems from its advantages in stimulating learning motivation, enhancing learning experience, creating psychological immersion, realizing situational learning and knowledge transfer。
