1. In science and technology development
Virtual reality can shorten the development cycle and reduce costs. For example, the Chrysler Corporation in early 1998 will use virtual reality technology, in the design of a two new types of cars made a breakthrough, for the first time to make the design of the new car directly from the computer screen into the production line, that is to say, completely omitted the intermediate trial production. As a result of the use of excellent virtual reality technology, Chrysler avoided 1,500 design errors, saving eight months of development time and 80 million dollars. The use of virtual reality technology also allows for automobile crash tests to be conducted, showing the consequences of crashes under different conditions without the use of a real car. Virtual reality technology has become one of the three major means for human beings to explore the laws of the objective world, together with theoretical analysis and scientific experiments. It can be used to design new materials, so that the effect of changing the composition on the material's performance can be understood in advance. It is possible to know how parts made from such materials are damaged in different stress situations before the materials are even manufactured.
2. Commercially
Virtual reality is often used in sales pitches. For example, when bidding for construction projects, the design of the program with virtual reality technology, you can take the owners into the future of the building to visit, such as the height of the door, window orientation, how much light, the house decoration, etc., can be empathetic. It can also be used for tourist attractions and the promotion of goods with many functions and diverse uses. Because the use of virtual reality technology to show the charm of such commodities, more attractive than the text or picture publicity alone.
3. Medical
Virtual reality applications are roughly of two types. One is the virtual human body, that is, the digital human body, so that the mannequin doctor easier to understand the structure and function of the human body. The other is a virtual surgical system, which can be used to guide the conduct of surgery. Militarily, the use of virtual reality technology to simulate the process of war has become the most advanced multi-fast and economical way to study war and train commanders. It is also due to the high level of virtual reality technology that nuclear weapons can be continuously improved despite the absence of nuclear testing. The war laboratory can also play a huge role in testing the pre-determined program for the actual war. 1991 before the start of the Gulf War, the U.S. Army will be the Gulf region of various natural environments and the Iraqi army's various data into the computer, to carry out a variety of combat scenarios simulation before the initial combat program. Later, the development of actual combat and simulation experiments were quite consistent with the results.
4. Entertainment
Application of virtual reality is the most extensive use. Britain sells a ski simulator. Users wearing a ski suit, feet on skis, hands on ski stick, head carrying a helmet display, hands and feet are equipped with sensors. Although in the bucket room, as long as you do a variety of skiing action, you can helmet display, see the pile of snow-covered mountains, canyons, cliffs and steep walls, one by one from the side of the past, the scene and in the ski resort really skiing feel the same.
5. Now
Virtual reality technology not only creates virtual scenes, but also creates virtual hosts, virtual singers and virtual actors. Japanese television launched the singer DiKi, not only singing and charming style, attracted countless fans have fallen, many fans want to see its face, forcing the TV station had to explain that she is just a virtual singer. The United States Disney company is also ready to launch a virtual actor. This will make the "actor" art of youth, vitality forever. Star pay to the sky is another reason for the use of virtual actors. After the virtual actor becomes the main character of the movie, the movie will become a branch of the software industry. Software companies will develop countless virtual actor software for people to buy. Granted, virtual actors will not be able to compete with real actors in terms of humor and human touch for a long time, if ever, but they do make good actors. The recent selection of the heroine of the computer-generated game show Tomb Raider as a globally recognizable character heralds the coming age of the virtual actor.
