Technical introduction
VR = Virtual Reality, or virtual reality technology, is actually a computer system that can create and experience a virtual world (Virtual World).
Friendliness is important
With the development of social economy, computers have become an indispensable and important part of social life. Friendly human-computer interface technology has long become an important topic of concern to people, because a relatively poor human-computer Interactive interfaces are likely to make a highly functional product unacceptable.
In general, there are two main research directions for human-machine interface technology: (1) How do people command the system (2) The system How to provide information to users.
As we all know, people’s experience in using computers (ie, the friendliness of the human-computer interaction part) directly affects people’s acceptance of the system Degree, and these two aspects directly determine the friendliness of the human-computer interaction part.
Virtual Reality
The advent of the Internet era makes human communication adopt new methods and enter new fields. The specific development process is as follows: command interface-character interface-graphical user interface-multimedia interface-virtual reality.
So, what is virtual reality technology?
Virtual Reality (Virtual Reality, referred to as VR), was created by the American VPL company founder Jaron Lanier in the 20th century Proposed in the early 1980s. Its specific connotation is: the comprehensive use of computer graphics systems and various reality and control interface devices to provide immersive technology in an interactive three-dimensional environment generated on a computer. Among them, the computer-generated, interactive three-dimensional environment becomes a virtual environment (ie Virtual Environment, VE for short).
On March 26, 2014, American social networking platform Facebook announced that it would spend US$2 billion to acquire Oculus, an immersive virtual reality technology company 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. And plans to expand the application of Oculus to businesses other than games. Prior to 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, familiar to more people outside the industry. According to industry insiders, virtual reality has ushered in spring again after more than 7 years.
March 2015 on MWC2015
, HTC Vive, a VR headset product jointly developed by HTC and Valve, which has produced original games such as Portal and Half-Life, was unveiled. The HTC Vive controller positioning system Lighthouse uses Valve’s patent. It does not need to use a camera, but relies on lasers and photosensitive sensors to determine the position of moving objects, which means that HTC Vive allows users to move within a certain range. This is the biggest difference between it and the other two major headsets Oculus Rift and PS VR. The kit is planned to be released before the virtual reality blowout in 2016, and it is very likely to meet with consumers at the end of 2016.
Application area
VR (virtual reality) technology can be widely used in urban planning, interior design, industrial simulation, restoration of historical sites, bridge and road design, real estate sales, tourism teaching, water conservancy and electricity, geological disasters , Education and training and many other fields, to provide practical solutions for it.
In the field of advanced manufacturing, standing in front of 3D images of large aircraft engines, “Can be disassembled at will”, the strength of virtual reality is vividly demonstrated. The operator can remove many parts of the virtual engine one by one, and then enter the inside of the engine. “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 discover and correct design defects and potential process problems in time, and improve The manufacturing success rate of product development.
Virtual reality technology is also very useful in the field of education and training. Create conditions for teaching functions that are not available or difficult to complete in real experiments. 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, which can project the works designed by college students on the wall, ceiling and ground. For example, a student designed a shower room, he can use this system to show it in the laboratory, the same size as a real shower room. After creating this kind of teaching environment, teachers can communicate with students more conveniently about the pros and cons of each link, and make changes at any time.
Some corporate training programs are also inseparable from virtual reality. Take the petrochemical industry as an example. As we all know, large-scale petroleum irrigation areas concentrate a large number of hazardous chemicals. If they are not handled properly, they may cause fires, explosions, and secondary disasters such as environmental pollution. Therefore, the government and enterprises have put forward high requirements for the safety of large-scale oil irrigation areas and the professionalism of operators. Virtual reality technology can build an emergency rescue and safety training system for the storage tank area
, it can not only present various scenes of the operation process to employees , To guide them to learn and master safe operation skills, and to simulate accidents and raging scenes, allowing employees to carry out rescue operations in immersive virtual images.
Movies
At the US Sundance Film Festival in early 2015
, a VR short film “LOST” made entirely on CG It has attracted a lot of heated discussion. In July of the same year, the “LOST” production company also brought their second VR short film “HENRY”. Unlike the previous “LOST”, this time they designed an “interactive” scene in the film, which changed the audience’s completely passive experience. Even Lin Yibin, the director of the “Fast and Furious” series, shot a VR short film “HELP” this year. This shows that the spring breeze of VR has indeed begun to blow towards the film industry.
Painting
Google created Tilt Brush on the basis of the VR device HTC Vive jointly developed by HTC and Valve.
Vive’s left and right controllers to realize painting creation. The controller on the left maps a cube in the virtual space, displaying the control panel menu, and you can turn the cube to make selections; the controller on the right is equivalent to a mouse, and there will be an English prompt when the cursor moves to the corresponding menu. The drawing board is the entire three-dimensional space, you can set the wallpaper background for it, and the lines can also be freely set with colors.
Virtual reality games
Currently, virtual reality games can be experienced through HTC Vive on the SteamVR platform.
Steam’s official webpage shows that there are currently 204 games that support virtual reality. Among them, there are many masterpieces like “Half-Life”, and all recommended games support the base station motion capture system.
Domestic industry development
From Beginning in 2015, many domestic VR companies have successively obtained 100 million-level financing. Among them, Ant Vision’s A4 round of financing of 300 million yuan has become the largest domestic VR industry investment, demonstrating the capital market’s enthusiasm for VR.
Entering 2016, known as the “first year of VR”, standards are still to be determined and order to be established. This provides opportunities for Chinese companies including Ant Vision. Since 2014, YTV has entered the VR industry. As one of the forerunners in the industry, Antvision has grown into a unique force in the industry despite the gap in size from the international giants. “When designing products, Antvision does not blindly follow the so-called trend, but has its own views and creations.” At this exhibition, Antvision brought two new products to surprise appearances, becoming a new industry force that has attracted much attention from the industry. On September 14, 2015, under the guidance and support of the Information Office of the State Council, the National Tourism Administration and the Chinese Consulate General in New York, and hosted by Wuzhou Communication Center, the first large-scale overseas promotion campaign using virtual reality technology to showcase Chinese tourism resources and promote Chinese culture” “Beautiful China Experience Day” was successfully held in the United States for the first time. After wearing the 3Glasses helmet, the participants of the “Beautiful China” experience day expressed incredible experience of the virtual travel experience. 3Glasses is one of the earliest companies engaged in VR exploration in China and has released Asia’s first one. The VR helmet 3Glasses D1 and the world’s first mass-produced 2k screen VR helmet 3Glasses D2 will be stationed in the Shenzhen Industrial Exhibition Hall for free experience for social groups and ordinary citizens. China’s creation of native VR power represented by 3Glasses is leading China’s virtual reality Going to the world. Dapeng VR is the leading brand of domestic VR, with a market share of 67% in the PC-side VR market, and is the first brand to enter the Alibaba VR laboratory. Dapeng VR also has a wealth of game and video resources . It cooperates with iQiyi, Wasu Media, Thunder and Aofei Animation to produce content for VR all-in-one machines. Hundreds of immersive VR games built-in completely subvert our previous game methods; we can also use this The VR all-in-one machine can experience the movie watching experience of the IMAX movie theater at any time; or watch the celebrity concert through the VR all-in-one machine, let us feel the shock of being on the scene. Entering 2016, known as the “first year of VR”, the standard is still to be determined and the order is yet to be determined Established. This provides opportunities for Chinese companies including YTV. Since 2015, many domestic VR companies have received 100 million-level financing. Among them, YTV has become the largest domestic VR with an A4 round of financing of 300 million yuan. Industrial investment shows the capital market’s enthusiasm for VR.
