Application field of virtual reality

The application of VR technology is extremely extensive. Helsel and Doherty made statistics on 805 VR research projects that have been carried out in the world in 1993. The results show that the current applications in entertainment, education and art occupy the mainstream, reaching 21.4%. Secondly, military and aviation reached 12.7%, medicine reached 6.13%, robots accounted for 6.21%, and commercials accounted for 4.96%. In addition, there are also considerable proportions in visual computing and manufacturing. A brief description of some of its applications follows.

Medical vr

The application of VR in medicine has very important practical significance. In the virtual environment, a virtual human body model can be established. With the help of trackballs, HMDs, and sensation gloves, students can easily understand the structure of various organs inside the human body, which is much more effective than the existing method of using textbooks.

In the early 1990s, researchers such as Pieper and Satara built a virtual surgical trainer based on two SGI workstations for leg and abdominal surgery simulations. This virtual environment includes virtual operating tables and surgical lights, virtual surgical tools (such as scalpels, syringes, surgical forceps, etc.), virtual mannequins and organs. With HMD and sensation gloves, the user can perform surgery on a virtual mannequin. However, the system needs to be further improved. If you need to improve the realism of the environment, increase the network function, so that it can train multiple users at the same time, or work under the guidance of foreign experts.

In addition, VR technology is of great significance in remote remote surgery, planning of complex operations, information guidance of surgical procedures, prediction of surgical outcomes and improvement of sputum status of disabled people, and development of new drugs.

Entertainment, art and education vr

Rich sensory capabilities and 3D display environment make VR an ideal video game tool. Since the realism of VR in entertainment is not too high, VR has developed most rapidly in this respect in recent years. For example, Chicago (Chicago) opened the world's first large-scale VR entertainment system for multiplayer. The theme is about a future war in 3025; a VR game system called "Virtuality" developed in the UK, equipped with HMD greatly enhances the sense of reality; in 1992, a system called “Legeal Qust” added artificial intelligence to make the computer have self-learning function, which greatly enhanced the fun and difficulty, and made the system get the year. VR Product Award. In addition, VR has also shown good prospects in home entertainment.

As a medium for transmitting display information, VR's potential application capabilities in the future art field cannot be underestimated. VR's presence and interaction ability can transform static art (such as oil painting, engraving, etc.) into dynamic, which allows viewers to better appreciate the author's ideological art. In addition, VR improves the artistic expression ability, such as a virtual musician can play a variety of musical instruments, people with inconvenience or people who are far away can go to the virtual concert hall in his living room to enjoy concerts, etc. Wait.

The potential application value of art also applies to education. For example, in explaining some complex system abstract concepts such as quantum physics, VR is a very powerful tool. Lofin et al. established a “virtual physics laboratory” in 1993. Used to explain certain physical concepts such as position and speed, strength and displacement.

Military and aerospace industry VR

Simulation training has always been an important topic in the military and aerospace industry, which provides a broad application prospect for VR. DARPA, the US Department of Defense's Advanced Research Projects Agency, has been working on a virtual battlefield system called SIMNET since the 1980s to provide tank coordination training that can connect more than 200 simulators. In addition, VR technology can be used to simulate a zero-gravity environment instead of the current non-standard underwater training astronauts.

Urban planning VR

VR technology is often used in urban planning. VR technology can not only visually represent the virtual urban environment, but also simulate the city under various weather conditions, and can understand the drainage system and power supply system at a glance. Road traffic, ditches and lakes, etc. Moreover, it can simulate the sudden occurrence of natural disasters such as hurricanes, fires, floods, and earthquakes. It plays a pivotal role in the government's work in urban planning.

Interior design

In the interior design application, VR technology not only can perfectly represent the indoor environment, but also can walk freely in the three-dimensional indoor space. At present, the industry commonly used VR technology for indoor 360-degree panoramic display and indoor roaming, has been well received, and can not only roam indoors, but also use VR technology to make pre-decoration system, which can instantly change the color of the wall or paste it. Different materials of wallpaper, you can also change the color of the ground or paste different wooden floors, tiles, etc., can move the position of the furniture, change different decorations. All of this will be perfectly represented under VR virtual reality technology.

Cultural relic protection

VR technology is also widely used in cultural relics protection. Egypt's pyramid has been an online experience center, using panoramic virtual technology and 3D virtual technology, and IBM has successfully used VR virtual reality technology to carry out the overall digital virtualization of the Forbidden City in Beijing. . Now everyone can see the digital three-dimensional Forbidden Palace directly on the Internet. (See: "IBM builds the virtual Forbidden City online" article)

traffic

Whether it is in the air, land or ocean river traffic planning simulation, VR virtual technology has its unique advantages, not only can use 3D GIS technology to fully display various traffic routes, but also can dynamically simulate various natural disasters. Happening.

real estate

In recent years, in the performance and promotion of real estate, VR virtual reality technology has been used more and more, and gradually replaced the effect map and three-dimensional animation. Using VR virtual technology can not only perfectly represent the environment and facilities of the entire community. It can also represent green belts, fountains, rest areas, sports fields, etc. that are not existing but will be built. Not only that, but users can also roam freely in the entire community and carefully appreciate every scene of the community. Greatly stimulated the feelings of the viewer.

game

For the development of games, VR technology is more suitable for development: role-playing, action, adventure, and racing games. The advanced image engine is no less than the image performance of the current mainstream game engine. And the integration of the dynamics and AI system provides convenience for the development of the game.

Home appliance

In the display, exhibition and release of home appliances, the use of VR technology can not only perfectly represent the appearance of the product, but also the performance of its functions. Moreover, the home appliance industry has a wide variety of products and a large number. The market demand is very large, whether it is the use of panoramic virtual, video virtual or three-dimensional virtual technology can make a big difference in the home appliance industry.

geography

In the geographical application of VR technology, the three-dimensional GIS geographic information system is mainly used to express the intuitive three-dimensional topography, which provides convenience for geographers and provides reliable reference data for related engineering construction.

education

In the field of education, VR technology mainly exerts its interactive and vivid performance effects, and is used for simulation of related courseware such as solid geometry and physical chemistry. And in the relevant professional training institutions, VR virtual reality technology can provide more assistance for students, such as virtual driving, simulation of various traffic rules. Special equipment simulation operations, simulation equipment, etc.

industry

In industrial applications, VR technology is mainly used in industrial park simulation, machine tool simulation operation, equipment management, virtual assembly, and industrial control simulation. Due to the characteristics of VR technology itself, it is very convenient, fast, accurate and accurate to engage in the above related work simulation.
