The following fields are the most widely used medical treatment with vr/ar at present. Ancient medical treatment pays attention to looking, hearing, asking and cutting, and the word "looking" ranks first among the four methods. In modern society, the importance of the word "Wang" is increasing, such as CT, B-ultrasound, X-ray fluoroscopy and other medical methods, all of which are observed and treated by the naked eye with the help of scientific equipment. Conceptually, AR technology is to display information that is invisible to the naked eye. Therefore, the application of vr/ar technology in anatomical training, teaching, diagnosis and treatment, image-guided surgery and other medical research is almost logical, which enables medical students to understand the patient's condition more intuitively and concretely and endows doctors with "perspective function".

The traditional profession of tourist guide is that its main job is to guide tourists to feel the beauty of mountains and rivers, and to help them with food, accommodation and transportation. Generally speaking, it is difficult to realize one-to-one tour guide service, and tourists can't make personalized "operations" on tour guides, and AR technology can perfectly realize this function. With vr/ar glasses, you can see scenic spot introduction information, road guidance information, surrounding recommendation information, etc., and you can set tracking or shielding at will according to your personal hobbies, which also avoids the hidden dangers of "tour guides cheating customers" and "strong buying and selling" that are popular today.

There are a large number of workers with high professional skills in the production sites of large-scale equipment such as airplanes, trains, automobiles and machine tools. Their operations are complicated and have many steps, and they are prone to omission or repetition. If the worker wears vr/ar glasses and carries out standardized operation according to the guidance of holographic images, he can see the next working steps, the information of the equipment or objects in front of him and the working action route. Not only avoid mistakes, but also improve efficiency and shorten the training period of workers. If workers encounter problems, wear vr/ar glasses and connect with experts remotely, experts can observe the situation from the first perspective of workers, and then understand the problems and guide workers how to deal with them. It is a practical technology for industry to greatly improve efficiency that services can be opened and called only by natural interaction such as eyeballs and gestures.

When real estate/home improvement developers sell houses, they will make a "sand table" in the sales department, so that buyers can directly preview the effect of the completed property, including road information, community greening, building spacing and so on. But no matter how realistic and beautiful the sand table map is, it is just a miniature version that stays on the desktop. Vr/ar technology can directly restore the final effect of real estate in an open space with a size of 1:1, so that consumers can feel it more intuitively. Similarly, in the home improvement industry, such as color matching and furniture placement, there is often a gap between the actually installed effect and the previously expected effect. With vr/ar technology, you don't need to wait until the decoration. You can use AR to decorate your house when you arrive at an empty and undecorated house, and you will see the decoration you want from your vr/ar equipment.

As the carrier of education, educational products are always boring if they are only the display of knowledge. Especially for children's educational products, the first point is to attract children and be fun. The characteristics of simulation and interaction of vr/ar technology can present abstract and obscure knowledge in a more vivid, intuitive and comprehensive way, enhance students' sense of substitution with immersive experience, and have certain entertainment, thus stimulating students' interest in learning. Children can not only get in touch with the real world outside the screen, but also enjoy a lot of interesting educational content, which will make parents very satisfied. For example, the 4D interactive children's textbook "Story of Journey to the West" and "4D Animal Show" created by China Augmented Reality Industry Alliance is the first batch of innovative children's education products designed by vr/ar technology in China, which is very popular in the market.

e-commerce itself has developed with the popularity of the Internet, which is the biggest benefit area of internet plus. Now, if the e-commerce industry wants to reproduce the explosive business growth in the past five years, it must rely on new technologies. Baidu believes that this year's AR field can be described as frequent actions, double eleven AR marketing, the big explosion of AR games, AR red envelopes, etc., which all confirm the feasibility of AR+ e-commerce.

Now vr can do vr movies, vr games, vr concerts, vr tourism, museums, vr education and training. AR Alliance thinks that the problem of vr is mainly the development of content. The more content, the more vr can do.
