What technology is VR?

Introduction: With the development of digital technology, digital has been integrated into us. VR (Virtual Reality, VR for short) was proposed by Jaron Lanier, founder of the American VPL company, in the early 1980s. Its specific connotation is: a technology that comprehensively utilizes computer graphics systems and various reality and control interface devices to provide an immersive feeling in an interactive three-dimensional environment generated on a computer. Among them, the computer-generated, interactive three-dimensional environment becomes the virtual environment (Virtual Environment, VE for short). The carrier for the realization of virtual reality technology is the virtual reality simulation platform, namely (Virtual Reality Platform, referred to as VRP). What technology is VR

Technology introduction

VR = Virtual Reality, virtual reality, or spiritual realm technology, is actually a computer that can create and experience a virtual world (Virtual World) system.

Friendliness is very important

With the development of social economy, computers have become an indispensable and important part of social life, and friendly human-computer interface technology has long been a concern for people. An important topic, because a poor human-computer interaction interface is likely to make a highly functional product unacceptable.

Generally speaking, the main research directions of human-computer interface technology have two aspects: (1) how people command the system (2) how the system provides information to users.

As we all know, people’s feelings about using computers (that is, the friendliness of the human-computer interaction part) directly affects people’s acceptance of the system, and these two aspects directly determine the friendliness of the human-computer interaction part. Spend.

Virtual reality

The advent of the Internet era has enabled human communication to adopt new methods and enter new fields. The specific development process is as follows: command interface? graphical user interface? multimedia interface? virtual reality.

So, what is virtual reality technology?

Virtual Reality (VR for short) was developed by Jaron Lanier, the founder of the American VPL company, in the 1980s. proposed at the beginning of the 1990s. Its specific connotation is: a technology that comprehensively utilizes computer graphics systems and various reality and control interface devices to provide an immersive feeling in an interactive three-dimensional environment generated on a computer. Among them, the computer-generated, interactive three-dimensional environment becomes the virtual environment (Virtual Environment, VE for short).

On March 26, 2014, the American social network platform Facebook announced that it would spend US$2 billion to acquire the immersive virtual reality technology company Oculus VR. Facebook CEO Mark Zuckerberg firmly believes that virtual reality will become another major event in computing platforms after mobile devices such as smartphones and tablets. It also plans to expand the application of Oculus to businesses other than games. Before this, Oculus was mainly used to create an immersive feeling for people during the game. Facebook's acquisition of Oculus has made virtual reality, a niche term in the technology industry, become familiar to more people outside the industry. According to industry insiders, virtual reality has ushered in spring again after more than 70 years.

Application fields

VR (virtual reality) technology can be widely used in urban planning, interior design, industrial simulation, historic site restoration, bridge and road design, real estate sales, tourism teaching, water conservancy It provides practical solutions in many fields such as electric power, geological disasters, education and training, etc.

In the field of advanced manufacturing, standing in front of a 3D image of a large aircraft engine, the strength of virtual reality that can be disassembled at will is clearly demonstrated. Operators can remove many parts of the virtual engine one by one and then enter the engine interior. ?Virtual reality? realizes cross-platform interactive design, virtual display, virtual assembly, CAE data visualization and other functions, greatly improving the design efficiency of the design team, enabling R&D personnel to promptly discover and correct design defects and potential process problems, and improve Manufacturing success rate of product development.

Virtual reality technology is also of great use in the field of education and training. Create conditions for teaching functions that real experiments do not have or are difficult to complete. When it comes to high-risk or extreme environments, inaccessible or irreversible operations, high cost, high consumption, large-scale or comprehensive training, etc., virtual reality technology can provide reliable, safe and economical experimental projects. The G-Magic Virtual Reality Laboratory of East China University of Science and Technology is an example of virtual reality teaching in colleges and universities. The laboratory has a CAVE cave-like virtual reality system that can project works designed by college students onto walls, ceilings and floors.

For example, if a student designs a shower room, he can use this system to display it in the lab as the same size as a real shower room. After creating this kind of teaching environment, teachers can more easily communicate with students about the design pros and cons of each link and make modifications at any time.

Some corporate training programs are also inseparable from virtual reality. Taking the petrochemical industry as an example, it is well known that large quantities of hazardous chemicals are concentrated in large petroleum irrigation areas. Improper handling may cause fires, explosions, and secondary disasters such as environmental pollution. Therefore, the government and enterprises have placed high demands on the safety of large-scale petroleum irrigation areas and the professionalism of operators. Virtual reality technology can build an emergency rescue and safety training system in the tank area. It can not only present various scenarios of the operation process to employees, guide them to learn and master safe operation skills, but also simulate accidents and raging fire scenes, allowing employees to Conduct rescue operations in immersive virtual imagery.

Domestic industry development

The market demand is huge, but the supply is slightly insufficient, especially there are not many companies with core intellectual property rights and excellent technology, and the industry as a whole lacks brand effect.

International Industry Development

In 2015, Google is internally developing an operating system customized for VR devices. There are dozens of engineers in the project. Once completed, it will lower the threshold for developing VR applications.
