Technical application of Virtual Reality

Medical application

The application of VR in medicine has very important practical significance. In a virtual environment, a virtual human body model can be established. By means of a trackball, HMD, and sensory gloves, students can easily understand the structure of various internal organs in the human body, which is much more effective than the existing textbook-based approach. Researchers Pieper and Satara built a virtual surgical trainer based on two SGI workstations in the early 1990s for leg and abdomen surgery simulations. This virtual environment includes a virtual operating table and surgical lights, virtual surgical tools such as scalpels, syringes, surgical forceps, and virtual human models and organs. With HMD and sensory gloves, the user can perform surgery on a virtual mannequin. However, the system needs to be further improved. For example, it is necessary to improve the environmental authenticity, increase the network function so that it can train multiple users at the same time, or can work under the guidance of field experts. VR technology has very important significance in predicting the outcome of surgery and improving the living conditions of disabled people, and even in the development of new drugs.

In medical schools, students can perform "autopsy" and various surgical exercises in virtual labs. With this technology, training costs are greatly reduced as it is not subject to specimens, venues, etc. Some virtual reality systems for medical training, internship and research have a very high degree of simulation and their advantages and effects are incalculable and incomparable. For example, a catheter-inserted arterial simulator may enable a student to repeatedly practice catheterization into an artery; an eye surgery simulator that creates a three-dimensional stereoscopic image based on the anterior ocular structure of the human eye with real-time tactile feedback that the student uses We can observe the whole process of simulating the removal of the lens, and observe the structure of the anterior eye vessels, iris and scleral tissue and corneal transparency. There are anesthesia virtual reality system, oral surgery simulator.

With virtual reality technology, surgeons can simulate surgeries on the display, move organs within the body, find the best surgical solution, and improve proficiency, before the real surgery. Virtual reality technology can play a very important role in long-distance remote-controlled surgery, planning of complicated surgery, information guidance in surgical procedures, prognosis of surgical outcomes, improvement of living conditions of disabled people, and even research and development of new drugs.

Entertainment applications

Rich sensory capabilities and 3D display environment make VR the ideal video game tool. VR has been the most rapidly evolving in this area in recent years due to the less demanding VR requirements for entertainment. Such as Chicago (Chicago) opened the world's first large-scale multi-use VR entertainment system, the theme is about a future war in 3025; developed in the United Kingdom called "Virtuality" VR gaming system with HMD, greatly enhance the sense of reality; 1992, a system called "Legeal Qust" because of the addition of artificial intelligence capabilities, so that the computer has a self-learning function, greatly enhancing the fun and the difficulty of the system by the year VR Product Award. In addition, VR also showed good prospects in home entertainment.

As a medium for transmitting and displaying information, VR should not underestimate the potential application of VR in the field of art in the future. VR's presence and interaction skills can transform static art (such as painting, sculpture, etc.) into a dynamic, enabling viewers to better appreciate the author's art of thought. In addition, VR enhances the ability of artistic expression, such as a virtual musician can play a variety of musical instruments, handicapped people or people in remote areas can live in his living room to a virtual concert hall, etc. Wait.

The potential value of art for education is equally applicable to education. For example, VR is a very powerful tool in explaining some complex concepts of system abstraction such as quantum physics. Lofin et al. Established a "virtual physics laboratory" in 1993, , Used to explain some of the physical concepts, such as location and speed, strength and displacement.
