VR Revolution: Virtual Reality will change life - Dr. Qingpu Lee


Abstract: Technology changes the world, VR changes life. Virtual reality VR originated from entertainment, bringing unlimited imagination space but also hit a large splash in all walks of life. With VR, you can stand on the distant Mars and feel the shock brought to us by the unknown planet. With VR, you can walk through mountains and rivers without leaving home and enjoy exotic scenery around the world. Wearing VR, you can walk into a virtual airplane and experience the science fiction world in the human brain. All of these seemingly incredible things can be done with the help of VR. This paper will further interpret what VR is and how VR will change our life by showing the development status of VR, experience characteristics and life applications.

Key words: VIRTUAL reality technology, characteristics, application, VR new life

1 VR is hot

Since The layout of Facebook in VR swept the technology circle like wildfire, Microsoft, Google, SONY, Samsung and other industrial giants have laid out their layouts, a large number of VR-related entrepreneurial teams continue to emerge around the world, the capital market is hot, and feverish players are eager to pay attention to VR. All of a sudden, VR is hot. Tencent, as the first social platform in China, has announced that VR wechat version is coming! Luo Yonghao, founder of Smartisan technology, expressed his determination for VR during an eight-and-a-half hour conversation with Luo Zhenyu, founder of the APP. He thinks the next generation of computing platforms, if nothing else, will be VR, which will be successful in about a decade. All industries are scrambling to get into the VR industry, which is booming under the high speed operation of 5G.

Virtual reality (VR) generates a virtual simulation environment through computer simulation system, which immerses users in a three-dimensional dynamic interactive simulation scene with the fusion of multi-source information related to vision, hearing, touch, smell, taste and so on. It is a computer simulation system that can create experiential virtual worlds. In the 1960s, Ivan Sutherland, known as the father of computer graphics and virtual reality, built the world's first virtual reality prototype. However, due to the underdeveloped information technology and excessive capital investment at that time, VR not only made no achievements in the consumer field and remained unknown for a long time, but also had a very small scale of application scenarios in the enterprise market. With the popularization of mobile intelligent terminals and the rapid development of chip computing capability, VR technology has ushered in this round of important development inflection point. The rapid development of 5G high-speed communication technology has solved the technical and capital dilemma of VR. VR entrepreneurship boom at home and abroad is rising again, and the capital market is once again hot attention.

2. Three major features to enhance experience

2.1 Display 720 degree panoramic view

Unlike 3D's "visual deception", VR not only allows users to fully immerse themselves in the virtual environment, which is indistinguishable from real and fake, but also adjusts and interacts with the user's intentions and actions in a timely manner. The most intuitive difference between VR and 3D is that VR has achieved a 720 degree panorama without dead Angle, that is, on the basis of the horizontal 360 degrees, plus the vertical 360 degrees, forming a 720 degree stereo panorama without dead Angle rotation range, which can show the panorama of "sky" and "earth". 720-degree panoramic technology is a new vision technology that is developing rapidly and becoming popular all over the world. It brings people a new sense of on-site visual and interactive experience. It can be widely used in 3D e-commerce, such as online real estate display, virtual tourism, virtual education and other fields. The scene displayed is the real scene, which is more realistic than the traditional virtual reality. Drag through the mouse, so that ordinary users operate more easily. Three-dimensional panoramic images are derived from the photographic capture of the real scene, which has a strong sense of reality. This is why the 720-degree panoramic display is so vivid and realistic.

2.2 Bring a more realistic experience

The biggest technical requirement of VR is immersion, the feeling of being immersed and confused between virtual and real. Some people think this experience can be described as "daydreaming". The more immersive the VR device, the more realistic the virtual scene the experiencer feels he is in. Ideally, when the experiencer reaches full immersion, it becomes impossible to distinguish between the virtual world and the real world. Total immersion includes the five senses of sight and hearing as well as touch, smell and taste, all of which fully realize the interaction between the experiencer and the virtual scene. There has been a lot of research going on around the technical difficulties of making VR close to reality. The first is about the display effect, including improving screen clarity, changing the internal structure of VR head display, etc. The second is more anthropomorphic support, including eye tracking, gesture recognition, motion-sensing vests, smell simulators, running simulators, etc., aiming to achieve "real" experiences in VR.

2.3 Give full play to man-machine interaction

Interactivity is the two-way interaction between the experiencer and VR scene through man-machine interface and control equipment. Currently, VR interaction methods are mainly divided into the following categories: "motion capture", "haptic feedback", "eye tracking", "gesture tracking", "direction tracking", "voice interaction", "sensor" and "a real venue". Wearing VR gloves, you can see your hands in the virtual scene, and the VR scene changes with the head Angle. Wearing VR goggles, you can realize the tactile feedback in the virtual scene. For example, when you play shooting games, you can feel the very real body sensation of shooting with live bullets and being hit. In the future, with the gradual improvement of motion capture, eye tracking and various sensor technologies, more and more consumer products are expected to be introduced gradually. Virtual reality VR is a new revolution of interaction mode, people are realizing the change of interaction mode from interface to space. In the future, multi-channel interaction will be the mainstream interaction form in VR era.

3 VR brings a new life mode

VR provides an opportunity to improve the efficiency of the demand side and the supply side. After users are involved through the terminal entrance of the virtual perfect experience space, it can bring zero-distance contact between demand (users) and supply (various resources, information flow, service flow, capital flow, etc.). With the development of 5G high-speed communication technology, all walks of life have begun to flood into VR, an emerging industry, unconsciously affecting all aspects of life.

3.1 VR + entertainment

VR originated from entertainment, rise in entertainment, the first into the horizons of ordinary people or entertainment. Since the VR boom, a large number of VR entertainment social brands have emerged around the world. Participants can take on new challenges in a virtual world with a backpack, helmet and sensor in hand. The main theme of the game is plot, secret escape and supernatural. However, no matter for offline experience or online game, the world created by VR can only be seen by the experiencer himself, and the "immersive" feeling cannot be shown to the outside world through screen recording. In the current trend of relying on social platforms for fission communication, VR can only rely on the most primitive "oral Amway" if it cannot break through this layer of shortcomings. From a product point of view, VR games have very different design logic from traditional games, including the UI. Developers also need to consider how they can interfere with the player's ability to drive the story in an immersive, free perspective. However, due to the shortage of funds, manpower and other reasons, many companies will choose VR and PC dual mode parallel. With the resurgence and even explosive growth of offline entertainment after the epidemic, it is hard to make a leap of judgment on whether VR can really break out this time. However, from an objective perspective, the globalization and prolonged pandemic does present opportunities for immersive experiences.

3.2 VR + education

With the recent rapid development of VR technology, VR education has broken the traditional rigid and single teaching method. In the classroom, students only need to wear VR virtual reality equipment and add relevant scenes, so they can easily realize the course teaching, completely replacing the traditional way of teachers dictating and writing on chalk. In addition, the interest in VR teaching software and the limitations of wearable devices make students highly focused, and this learning method can be said to be very efficient. And in traditional teaching, part of the scene may be the teacher can not use language to describe. If these scenes can be displayed, the effect must be better than language, just like allowing students to see the artistic conception depicted in ancient poems directly, which is more vivid and intuitive than the teacher's language description.

VR technology can also simulate the restoration of experimental equipment, so that the original expensive equipment can be readily available, effectively reducing the cost. And in the virtual scenario, students don't have to worry about toxic substances or the dangers of going wrong.

3.3 VR + tourism

VR's idea of infinite space has brought great breakthroughs to tourism. First, virtual tourism expands the influence of tourist attractions. Based on the panoramic images shot in real scenes, the real tourist landscape is built through WEB3D development and VR virtual reality technology, with animation and voice for cultural explanation. Viewers can freely choose sightseeing contents and routes for interactive experience, crossing the time and geographical restrictions, from within the province to outside the province, from home to abroad, and fully expanding the breadth of cultural communication. Secondly, the restoration of scenic spots and historic sites to reproduce the tourist landscape. Dream back to The Old Summer Palace, independently developed by Guangzhou Huarui Interactive, truly reproduces the full picture of the bustling Old Summer Palace, solves the problem of restoring ancient architectural sites and improves the depth of ancient architectural civilization. Furthermore, tourism planning is carried out. VR the idea of virtual reality technology and space can carry on the reasonable planning of tourist attractions, through the system modeling to generate the corresponding virtual reality system, then the human-computer interaction into the virtual scene experience to judge the merits of the planning scheme, and can be modified and auxiliary specifies a final plan, to speed up the development cycle and reduce design cost. Finally, better protection of cultural heritage and ecological environment. With the help of multimedia and AR augmented reality technology, China's ancient cultural heritage can be digitally displayed and effectively protected. Tourists can watch cultural relics from a distance without causing any damage. These precious cultural heritages can be preserved for a longer time if the problems of cultural relics being difficult to protect and vulnerable to disasters are solved.

3.4 VR + medical care

The most promising application of VR+ therapy is medical training. The fully immersive 3D surgical simulation can help train young doctors to watch and learn surgeries from the perspective of the operator, so as to maximize the approximation to the actual operation scenes and enhance the learning effect, which is of great help to more precise surgical learning. Psychologists have found that VR can bring other pleasant experiences besides super-exciting horror games, and in turn use VR technology to treat mental illness. Now medical students are widely used in VR technology under the simulation of human anatomy experiments, VR live surgery, vision correction, pain management, patient education, conversion disorder treatment, smoking cessation and so on. The combination of VR and the medical industry is gradually unfolding, and may become the main technology means of the medical industry in the future.

5. VR+ Social

Facebook became the first VR social platform when it bought VR equipment maker Oculus for $2 billion amid the VR boom. Tencent in China also announced that it would launch wechat VR version, and many VR social platforms have emerged to open a new world for users. In Facebook Spaces, users can design their avatars in VR using their avatars, choosing different hairstyles, face shapes, features and more. Once you've set up your avatar, you'll be able to experience the wonders of Facebook Spaces with a new identity.

3.6 VR + electrical contractor

Traditional e-commerce platforms are limited in the expression of commodity information, which can be seen but not touched. This is the most obvious gap between e-commerce platforms and physical stores. With the help of VR/AR technology, the future e-commerce platform can not only present the real appearance of goods, but also realize partial interaction. This is the value of VR/AR technology for traditional e-commerce, it can to some extent change the embarrassment of "visible and intangible". Taking JINGdong as an example, by introducing VR/AR technology, users can obtain a more intuitive shopping experience when using JINGdong APP. At present, JINGdong has transformed the technology into actual products in terms of AR trial makeup, 3D commercial details, AR real scene purchase, VR panoramic stores and other aspects. In addition, VR/AR technology related products have been fully laid in beauty makeup, 3C home appliances, home furnishing and other fields.

3.7 VR + military

In recent years, the application of VR technology in various industries is gradually mature, especially in the military and national defense construction has played a great role. 1, save expenses, reduce wastage, economic security. The use of VR technology allows soldiers to experience in virtual scenes, saving money and reducing the wear and tear of equipment. And training in the virtual battlefield will not be injured because of mistakes, relatively safe. 2, improve training efficiency, enhance combat ability. VR military simulation and drill system can deliver infinite virtual scenes to soldiers, which solves the problem of limited space and equipment. Multiple soldiers can wear VR equipment at the same time and carry out training in the same subject without affecting each other. They can also repeatedly train themselves in areas where they are not skilled, so as to improve training efficiency and enhance combat ability. 3, all kinds of war environment arbitrarily switch. VR can simulate a variety of war environments and thousands of battlefield emergencies. Trainees can select corresponding tactical movements through relevant VR equipment and experience different combat effects. This experience is no different from actual combat, and to a certain extent, exercise and improve reaction ability and psychological endurance. 4. Provide new ideas for exercises. VR technology can be used for military exercises and training, and large-scale theater and strategic exercises can be carried out in a relatively short time with a small cost, and problems that may occur in actual combat can be found and solved through a variety of exercises. Commanders can also observe the deployment of forces and battlefield conditions on both sides in real time, so as to judge the enemy situation and make a correct judgment, which also provides new ideas for exercises.

3.8 VR + industry

"VR technology is one of the main supporting technologies of Industry 4.0, and is an advanced means of innovative design of modern manufacturing products." Nanjing University of Science and Technology professor Chen Qian said. He believes that the application of VR in engineering design can effectively solve the problems of high risk and high cost of complex system structure. For example, designers can test products in the form of models through VR technology and collect market feedback, thus reducing product development time and cost. In the engineering training center of Nanjing University of Science and Technology, a large screen measuring nine meters long and three meters high is quite conspicuous. Students simply put on VR headsets and a realistic, three-dimensional engine appears before their eyes. If you want to understand the internal structure of the engine, just move the interactive handle in the hand, you can disassemble the engine, and every internal part structure will be exceptionally clear in front of everyone. At the same time, each structure can be zoomed in and out, and can even be viewed in all directions. For example, Kuntian automation applies it to parts disassembly and assembly, and on the basis of ITS system, with VR peripherals, makes the training more vivid and intuitive.

4 conclusion

Many people in the industry believe that VR is not only a hardware, a product, a field, it will be a product of the era of disruption. VR will usher in an era of change, perhaps ushering in a new era of commerce at a time when post-industrial wealth is overpowering and energy is running out. From the law of the development of science and technology, the development cycle of technology market generally needs to go through five stages, that is, the germination stage, the development stage, the trough stage, the recovery stage and the mature stage. Most new technologies will have a ups and downs road from concept to popularization. Up to now, the real immersive experience of VR devices has attracted the most attention and affection. Now with 5G, VR will once again make waves, bringing us deeper and more exciting experiences. VR is trying to create a new virtual reality interesting world, the future may change the way we live. VR is worth waiting for.
