This summer, "This! As soon as the fifth season of "Street Dance" was broadcast, it ranked first in the variety list with a full-end broadcast market share of 9.28%; According to Lighthouse Professional Edition, "This! That is, Street Dance 5 was launched for 1 hour, and the market share of real-time whole-network variety feature films was as high as 45%, accounting for nearly half. In the first phase, it ranked first in the comprehensive program of the whole network.

Behind the numbers, it reflects the word-of-mouth and popularity accumulated by a program in the past five years. After five years of enthusiasm, for many viewers, the summer without hip-hop is incomplete. Last year’s fourth season, "This! It is street dance that ended the last stage with the international elite challenge. What higher level can this program go to? The audience is full of great expectations and expectations, but it is undoubtedly an unknown challenge for the program creators.

This year, "This! In the fifth season, Hip-hop didn’t choose to move forward on the established safe road, but walked out of the comfort zone, started from the "new" and focused on the growth of the new generation with a responsibility of shouldering the future development mission of hip-hop culture. Under the brand-new theme of "Battle For Hope", the program is positioned as "Training Camp for Young Dancers" and the competition system has been upgraded. The contestants have to go through the selection and elimination again and again in three months to interpret the topic of "inheritance" of China street dance.

"this! It is the three highlights of the fifth season of Street Dance:

Cenozoic, Parallel Universe, Immersion Experience

1. Focus on the new generation of street dance in the future.

The core concept of street dance in the fifth season is "youth", with a brand-new lineup of dancers and a new generation of dancers becoming the absolute protagonists of this season’s program. In the training camp for young dancers, the proportion of "post-95" dancers exceeds 90%, and 50% are "post-00". The outstanding dancers in the first four seasons are incarnated as "master groups" to escort young dancers. Street dance needs representative figures, OG (predecessors), as well as young blood and young people’s own representatives. After the launch of the fifth season, young players such as Zaizai, Zhou Yuxiang, Ang Ang, Sniper and Badd machine quickly emerged with their strength. The program not only shows young people their own stage, shows the new generation of young people’s playing methods and preferences, their wild imagination, their different personalities, but also gives them propositions and challenges, and stimulates the infinite potential of young people with the competition system.

In the first round of points elimination, young dancers competed in the form of teams for their works, 1v1 and routine battle respectively. The upgraded competition system was even more cruel, from the original "tie-break" to a battle wheel battle, and the team that took the lead in completing the cumulative points goal won. The score was tied and the battle was very fierce. Finally, with the joint efforts of all the dancers, 32 rounds of the battle were completed, which directly set a new record for the number of rounds of the Battle on the street dance stage. As the team leader, young dancer Doudou, with a waist injury, still completed the performance of her work with high quality and participated in the battle session with great pain. Doudou’s persistence greatly inspired everyone on the scene, and the team members were even more uncompromising, and they became more and more brave, becoming the ultimate winner of the battle Wheel War in the absence of one person in the team. This shows us the enthusiasm and determination of this group of young people to dance, and also feels the spiritual core of the program "Let’s be brave sometimes and pass on hope".

2. Create a new concept of street dance parallel universe.

This season’s "This! It is street dance that puts forward the concept of "parallel universe" of street dance very imaginatively. Under the guidance of this core concept, the past four seasons can be regarded as a hip-hop universe bearing the glory of yesterday. In the fifth season, it is necessary to discover and create another new hip-hop universe, a world belonging to the future, which is in harmony with the fifth season, namely, youth and rookie competition.

The parallel universe of street dance is both traditional and contemporary; It belongs to both the pioneers and the later generations. They are parallel, complement each other, and even cross each other, breaking the "uniqueness". Plurality and richness are the core essence of parallel universes.

At the same time, the parallel universe also implies another important theme: growth. The parallel universe is full of unknowns. If you are in the parallel universe, can you imagine what you might be like in another parallel universe and how to deal with sudden challenges? Whether you will make efforts to become a better you. Therefore, the highlight of this season is not the "Great God", but how a young man chooses, grows up, becomes a stronger self gradually, and even moves from obscurity to an influential international stage.

3. Multi-scene immersive new dance beauty

The concept of street dance parallel universe needs to be further grounded through the beauty of dance in the program, so this season’s beauty of dance has made a big breakthrough than before. The original ambience design of four theme streets has been replaced by two parallel universes, one representing "tradition" and taking the old school style, and the other representing "future", which is full of futuristic sense of science and technology, and the two-dimensional plane dance beauty originally used as the background has been upgraded to a three-dimensional space in an all-round way, so that dancers can better blend in and perform, and also bring the audience the immersion feeling of shuttling between different parallel worlds.

This season’s dance beauty pays great attention to the creation of atmosphere and the experience of people in the space, creating daily social life scenes that young people are very familiar with, such as basketball square, skateboarding park, campsite, game room, singing room, barbecue house and so on. In these rich and varied scenes, young people show themselves, communicate and find companions through street dance, which is also the real social state of young people at present.

It is worth mentioning that the recording site of this season’s program itself is a building with a sense of the times, and the "row column", an element with historical specificity inside the building space, has been preserved and presented by the choreographer. In the beautiful dance design of the main stage of the race, two rows of towering reinforced concrete columns lead our view to a deep place, like a tunnel of time and space, which can return to the historical scene and witness the birth of a new history. In such a unique aesthetic space, silent and exploding, two cultures with different faces and styles have a fierce collision.

When we combine the new generation, parallel universe and immersive experience, this season’s "This! It is street dance that fully reflects the characteristics of the post-Internet era and the development trend of youth group culture. With the continuous development of street dance IP, derivative interactive applications of derivative programs and social attributes have been launched. It’s hip-hop, which shows us the infinite possibilities of hip-hop. It’s a medium, a field, or a universe that seeks the coexistence of souls.

The national comprehensive sample "this! It’s street dance

Write an advanced history of national synthesis in five seasons

"this! It’s street dance, which has maintained its innovation and vitality for five seasons. From the ice-breaking in the first season, the broken circle in the second season, to the leap in the third season, and the transnational in the fourth season, we can say, "This! In four years’ time, It’s Street Dance presents the audience with an encyclopedia of street dance culture, a list of street dance celebrities, intergenerational inheritance, countless scenes, etc., and has completed a whole set of knowledge and aesthetic system structure about street dance.

Simon Lu, the general director, said frankly that although this program puts the culture of hip-hop circles at a stage where the mass communication can be perceived, it uses the resources accumulated by China hip-hop circles over the years. This year is a "hematopoietic" program, and a "hematopoietic" program is always more difficult than a consumption-oriented program. This is for sure.

Since the five seasons, this program has been embedded in the historical process of the progress and development of domestic variety shows in terms of conceptual changes and commercial expansion, and has also been continuously improved and enlarged in three dimensions.

At the level of program innovation, "This! It is street dance that has created an original and internationally recognized program model. The program firmly grasps "battle" and "Work", the two core elements of street dance, and combines the beautiful dance form with visual impact to make the charm of this culture itself visible to everyone, reflecting the creativity and value of art itself.

At the level of industry value, innovation, breaking the circle and cross-border integration. "this! It is street dance that shoulders the mission of promoting street dance culture and cultivating new dancers, and promotes the rapid development of street dance industry at home and abroad.

At the level of social value, "this! Hip-hop reflects the social responsibility of the creators and platforms, deeply resonates and connects with social reality and people’s current life feelings, and always advocates positive values. As the general director Simon Lu said, "I have always felt that making programs can’t be too light. Aside from the beauty and entertainment of the program itself, a program should also give people a sense of faith and strength. In this program, I hope everyone can see that when the younger generation encounters particularly great difficulties and challenges, they can stand up and be willing to fight. If people who watch this program are in a particularly unstable or insecure state, they can also get some encouragement from it. In short, "hope" is very important. "

The fifth season "This! The slogan of "Street Dance" is "Battle for Hope". From Peace and Love to Battle for Hope, the fifth season will become a landmark iteration of this variety show. The "Battle" spirit of hip-hop gives the program the courage to break through without setting limits, which is the inexhaustible vitality of the program. I hope this spirit can be injected into a new generation of young audiences with this national variety show and become a spiritual force that affects the growth of a generation.

　　China Jiangxi Network Ganzhou News CorrespondentLiu binReport: At about 17: 00 Beijing time on April 19th, 2018, news came from the headquarters of FAO in Rome, Italy. At the 5th GIAHS International Forum, 14 projects in China, Egypt, Japan, South Korea, Mexico, Portugal, Spain and Sri Lanka were awarded the title of "Global Important Agricultural Cultural Heritage". "Rice Terrace System in Southern Mountainous Areas of China"-"Hakka Terrace in Chongyi, Jiangxi" was officially recognized as an important global agricultural cultural heritage, and was awarded the license by FAO on the spot. Liu Chunxiang, the county leader, attended the forum in Rome on behalf of the county party committee and government and accepted the award from Ms. Sai Mei Duo, Deputy Director-General of FAO.

　　It is reported that "Jiangxi Chongyi Hakka Terrace" existed in the Southern Song Dynasty, which was built in the late Ming Dynasty and completed in the early Qing Dynasty, with a history of more than 800 years. Looking at the Hakka terraces, I saw a chain-like belt, winding from the foot of the mountain to the top of the mountain, layered on top of each other and strewn at random; Seen from a height, the beautiful lines of terraced fields are one by one, or parallel or cross, winding like spring snails and spreading like a cloud tower, showing the fascinating curvaceous beauty. Its lines are flowing, natural and unrestrained, and it is known as the "beautiful ladder", and it is also one of the oldest ancient terraced fields in China. Pieces, rows and rows of terraced fields are like a heavy epic across the world, witnessing the wisdom and sweat of Hakka ancestors and becoming a spectacle of Hakka farming civilization. At present, Chongyi Hakka Terrace Reserve covers an area of more than 40,000 mu, stretching over Shangbao, Fengzhou and Sishun townships, with more than 30,000 mu in Shangbao alone. The scope of the reserve is 73 kilometers from east to west and 59 kilometers from north to south.

Avatar 2

Time Network News In the last weekend of 2022 in North America, Avatar: The Way of Water (referred to as Avatar 2) reached 66.84 million US dollars for three consecutive championships, up 6% from last week, with a total of 424 million US dollars in North America and 1.4 billion US dollars in the world. (The data source of this article is boxofficemojo)

Last week, the North American market rose by 4% as a whole. The runner-up Cat in Boots 2 and the runner-up Panther 2 rose by 31.2% and 38.3% respectively from last week.

Let’s briefly summarize the North American market in 2022. Last year, the box office in North America was estimated to be 7.37 billion US dollars (50.8 billion RMB), up 64% from last year’s 4.48 billion US dollars, but it was still far from the pre-epidemic level. In 2019, North America reached 11.4 billion US dollars.

In 2022, North America mainly relied on the summer file led by the prequel of Top Gun 2 and Jurassic World 3’s Little Yellow Man with Big Eyes: Despicable Me, and the market began to slump in September until the release of Avatar: The Way of Water.

This year, the total box office in North China was converted into RMB 50.8 billion, 70% higher than the 30 billion in, and it became the largest movie market in the world again.

In the last weekend of 2022, North America mainly relied on Avatar 2, which rose by 2% month-on-month in the third week, even better than the performance of Avatar, which fell by 9.4% in the third week 13 years ago. Of course, this downturn has something to do with the overall market rise. North America was hit by a snowstorm on Christmas weekend, and many viewers delayed their plans to enter the cinema.

Battle for the annual crown

The American media estimated that the box office of the film will exceed 440 million dollars on January 2, and it will be three times as big as the opening box office in the third week, while the box office of Top Gun 2 will be 395 million dollars in the third week. Avatar 2 seems to have the possibility of surpassing Top Gun 2 in the North American market and winning the annual title in North America.

In the international market, "Avatar 2" rose 4% from last week, with a global total of $1.397 billion, surpassing "Harry Potter and Under the Deathly Hallows" and becoming the 15th movie in the global film history.

The film’s performance in Britain and Japan was average, but it was a big hit at the box office in France, South Korea and India, and the film also exceeded RMB 1 billion in the mainland market of China. Top Gun 2 has a global box office of $1.49 billion, and Avatar 2 is likely to top the global box office in 2022 this weekend.

Cat in Boots 2 grossed $134 million worldwide.

The box office of "Cat in Boots 2" began to stabilize. In the second week of its release, it rose 35% month-on-month and won the runner-up of $16.78 million, with a total of $60 million in North America and $134 million in the world.

In the eighth week of its release, Panther 2 earned 4.83 million US dollars, up 38.3% from the previous month. The cumulative US$ 437 million in North America surpassed the US$ 411 million in Doctor Strange 2, becoming the runner-up in North America in 2022, and the global cumulative box office was 820 million US dollars.

This week’s new film

"Doll Megan" horror/thriller global release

Starring: Violet McGraw, Allison Williams

Plot: The story focuses on a talented robot expert of a toy company. He developed a doll M3GAN with AI and programmed it to establish an emotional connection with her newly orphaned niece, but the doll’s excessive desire for protection led to terrible results.

　　In a blink of an eye, 2018 is about halfway through. In July, there is a big wave of new policies about your wallet: the reduction of tariffs on imported consumer goods, the cancellation of traffic roaming fees, etc. What other new policies are there?

　　1 enterprise employees’ pensions shall be subject to the central adjustment system.

　　The State Council recently issued the Notice on Establishing the Central Adjustment System of the Basic Endowment Insurance Fund for Enterprise Employees, and decided to establish the central adjustment system of the endowment insurance fund, which will be implemented on July 1, 2018. On the basis of the current provincial overall planning of basic old-age insurance for enterprise employees, a central adjustment fund for old-age insurance will be established, and the old-age insurance funds in various provinces will be appropriately adjusted to ensure that basic pensions are paid in full and on time.

　　The relevant person in charge of the Ministry of Human Resources and Social Security said that the implementation of the central fund transfer system will not increase the burden on enterprises and individuals and will not affect the treatment of retirees. First, do not increase the proportion of contributions paid by enterprises and individual employees. The establishment of a central fund adjustment system is mainly to adjust the surplus and deficiency of funds between provinces. The total income and expenditure of the national endowment insurance fund in the current period has not changed, and enterprises and individual employees do not need to pay extra fees, which will not increase the overall burden of society. Second, it will not change the current pension insurance benefits calculation and adjustment methods, and will not affect the personal benefits of retirees. In some provinces, the amount of funds borrowed is greater than the amount of funds allocated. In these provinces, the burden of old-age care is relatively light and the fund support ability is strong. After adjustment, it will not affect the timely and full payment of current pensions. In some provinces, the amount of funds allocated is greater than that of the above solution. Through adjustment, the pressure of fund payment can be appropriately alleviated, and the basic pension can be better guaranteed to be paid in full and on time.

　　2. Adjustment of social security payment base

　　Many places in the country have successively announced the social security payment base in 2018. Taking Beijing as an example, the lower limit of the payment base for employees participating in basic old-age insurance and unemployment insurance is 40% of the average monthly salary of employees in Beijing in 2017, with a minimum of 3,387 yuan, which is 305 yuan higher than last year; For employees who participate in basic medical insurance, industrial injury insurance and maternity insurance, the minimum payment base is 60% of the average monthly salary of employees in this city in 2017, with a minimum of 5,080 yuan, up 456 yuan from last year.

　　Social security payment is related to the treatment of the insured after retirement. Only when a certain payment level is reached can a better treatment level be achieved. If the payment level is too low, the pension level is still low. In other words, the payment level will increase with the increase of average salary, and the future treatment level will also increase.

　　3. The tax incentives for scientific and technical personnel will be "received"

　　The Ministry of Finance, the State Taxation Administration of The People’s Republic of China and the Ministry of Science and Technology jointly issued the Notice on Individual Income Tax Policies for Scientific and Technological Personnel to Earn Cash Rewards from Their Post Scientific and Technological Achievements, which made it clear that since July 1, 2018, non-profit research and development institutions and institutions of higher learning approved according to the law on promoting the transformation of scientific and technological achievements, the cash rewards given to scientific and technological personnel from their post scientific and technological achievements can be included in the "salary and salary income" of scientific and technological personnel in the current month at a reduced rate of 50%, and personal income tax can be paid according to law.

　　It is cheaper to import daily consumer goods.

　　With the approval of the State Council, the MFN tariff rate of some consumer goods will be reduced from July 1, 2018, involving 1449 tax items, and the average tax rate will be reduced from 15.7% to 6.9%, with an average decrease of 55.9%. Reduce the average import tariff rate of clothing, shoes and hats, kitchens and sports and fitness products from 15.9% to 7.1%; Reduce the average import tariff rate of household appliances such as washing machines and refrigerators from 20.5% to 8%; Reduce the average import tariff rate of processed foods such as aquaculture, fishing aquatic products and mineral water from 15.2% to 6.9%; The average import tariff rate of washing products, cosmetics such as skin care and hairdressing and some medical and health products will be reduced from 8.4% to 2.9%.

　　5. Tariff reduction of imported cars and parts.

　　6. The vehicle purchase tax will be levied on the trailer by half.

　　The Ministry of Finance, State Taxation Administration of The People’s Republic of China, and the Ministry of Industry and Information Technology jointly issued the Announcement on Reducing Vehicle Purchase Tax on Trailers. From July 1, 2018 to June 30, 2021, the vehicle purchase tax will be reduced by half. The date of purchase shall be determined according to the issuance date of the Uniform Invoice for Motor Vehicle Sales, Special Payment Letter for Customs Tariff or other valid documents.

　　7. Preferential tax policies for venture capital enterprises and angel investment individuals.

　　The Notice on Tax Policies for Venture Capital Enterprises and Angel Investors jointly issued by the Ministry of Finance and State Taxation Administration of The People’s Republic of China promoted the preferential tax policies for venture capital enterprises and angel investors, that is, the preferential policies for venture capital enterprises and angel investors to invest in seed-stage and start-up technology-based enterprises, and the taxable income was deducted by 70% of the investment amount, which was implemented nationwide by eight pilot areas of comprehensive innovation reform and Suzhou Industrial Park.

　　This Notice clarifies that the personal income tax policy for angel investment will be implemented as of July 1, 2018, and other policies will be implemented as of January 1, 2018; The above-mentioned tax policy can be applied to the investment that occurred within 2 years before the implementation date and has been invested for 2 years after the implementation date and meets the prescribed conditions.

　　8. Traffic "roaming" fee is cancelled

　　On June 22nd, China Mobile, China Unicom and China Telecom successively announced that, starting from July 1st, 2018, the roaming fee will be cancelled, and the provincial traffic of new and old mobile phone users will be upgraded to domestic traffic (excluding Hong Kong, Macao and Taiwan traffic).

　　Previously, the Ministry of Industry and Information Technology launched a series of measures to reduce the growth rate of mobile traffic, including: from July 1, the "roaming" fee for mobile traffic will be cancelled, and basic telecommunications companies will be encouraged to launch large-flow packages. The average unit price of mobile traffic will be reduced by more than 30% during the year. Further reduce household broadband charges and international, Hong Kong, Macao and Taiwan roaming charges. Promote enterprises to optimize and streamline tariff packages, and study and introduce relevant policies and measures to standardize tariff management. Support all localities to expand the coverage of wireless networks in public places and provide users with free Internet access services.

　　9. Some high-speed rail tickets are discounted by 6.5%

　　Starting from July 5 this year, the announced fares of high-speed trains running on the six sections of Hefei-Wuhan, Wuhan-Yichang, Guiyang-Guangzhou, Liuzhou-Nanning, Shanghai-Nanjing and Nanjing-Hangzhou were optimized and adjusted. This time, it is clear that the published fare is the highest price limit. Railway-related enterprises can lower the fare within the price limit by season, time, seats and sections according to the passenger flow, with a maximum discount of 6.5%. Compared with the current situation, the adjusted executive fare has generally increased and decreased.

　　10. Tianjin will raise the unemployment insurance standard from July 1st.

　　A few days ago, Tianjin issued a notice, starting from July 1 this year, it will raise the unemployment insurance payment standard.

　　According to the "Notice on Improving the Payment Standard of Unemployment Insurance in Tianjin", if the payment period is from the first month to the twelfth month, the monthly payment standard will be raised from 1150 yuan to 1240 yuan; For the 13th to 24th months, the monthly payment standard was raised from 1,110 yuan to 1,200 yuan, respectively increasing the 90 yuan.

　　At the Los Angeles Convention and Exhibition Center, gamers are experiencing virtual reality (VR) devices. Bright pictures/vision china

　　With the establishment of virtual reality technology (VR) laboratory in Alibaba, Stormwind TV released the first VR TV, Huawei announced its first generation of VR glasses products, and the VR industry also rose. It can be predicted that in the near future, the wide application of mobile Internet, big data and other information technologies will promote the further development of VR technology. So how is the so-called virtual reality technology realized?

　　1. Frontier disciplines of integrated application of software and hardware.

　　Virtual reality technology (VR) is a computer simulation system technology to create and experience a virtual world. That is to say, VR uses computers to generate a simulation environment, and uses multi-source information fusion for interactive three-dimensional dynamic visual scene and system simulation of entity behavior to immerse users in this environment. Up to now, there is no universal definition of it in the world, but it can generally be considered that it creates another unreal world that is as real, interactive and immersive as possible for human beings outside the real space by using various human-computer interaction technologies, so that human beings can roam in it, experience the most real virtual space and walk in their dreams without any restrictions.

　　VR has been widely used in new media, aerospace, military, engineering and other cutting-edge scientific and technological fields, and will be more widely used in our daily life as an advanced technical means. Because most of the monitors used by virtual reality in human-computer interaction are helmet-mounted enhanced portable display systems, it is one of the most promising application fields of portable display systems. Users only need to wear virtual reality equipment, such as helmets, glasses, etc., and they can feel all kinds of scenes set in the device.

　　VR system generally includes user control systems, such as human motion monitoring, control devices such as joystick, keyboard and mouse, and simulation feedback systems and processing systems for human senses such as vision, hearing, touch, smell and taste, as well as information display systems perceived by human beings, such as monitors, stereos and three-dimensional seats. Among them, visual and auditory control and simulation are the main development direction of VR at present, and helmet-mounted enhanced portable display system is the main product form used by users.

　　2. Construct a virtual space in advance in the computer.

　　VR is an interdisciplinary subject that relies on a large number of computer software technologies such as artificial intelligence, pattern recognition, graphics, bottom interface and new display technology, field sensor technology, force feedback system, wireless and wired communication technology. In essence, VR is the representation of the real world and the realization of dreams; From a technical point of view, it is a comprehensive application of cutting-edge technologies in the fields of software and hardware and an object-oriented comprehensive technology development.

　　VR enables people to experience a fantastic virtual reality while wearing a helmet-mounted enhanced portable viewing system. In fact, these virtual reality scenes use complex software technology to construct a real virtual space in the computer in advance. Every point in the space has many dimensions of information such as coordinates, colors, normals, logical relationships and so on in X, Y and Z. The computer then determines the position of people in the virtual scene through user input devices such as sensors, joysticks and mice, and finally reproduces the picture to the user’s eyes through the computer, thus creating a virtual space.

　　If such a series of tasks can be connected, and the operation time of the whole system is less than the visual retention time of people, users will have the feeling of roaming in the virtual reality world on the virtual image display screen of the head-mounted enhanced portable display system. VR is to create a virtual environment that makes you feel that this is reality. Entertain and attract you through this fictional reality.

　　3.MR— — Break through the boundary between virtual and reality

　　In addition to VR technology, there is also augmented reality technology, namely AR. Now there are only more than 20 authoritative companies in the world conducting research. Google’s technology is relatively mature, and its goal is to put the virtual world in the real world and interact with it on the screen. This technology was first put forward in 1990. With the improvement of the computing power of portable electronic products, it is expected that its application will be more and more extensive.

　　In essence, AR is the interaction between digital media and the real world. The imaging concept of AR and the immersive imaging experience of VR have created a hybrid virtual reality technology, namely MR, which is based on holographic projection reality. At the Microsoft Developer Summit held in June this year, satyanarayana nadella, CEO of Microsoft, emphasized the importance of its hybrid virtual reality technology equipment — — The correct "opening" way of Hololens is neither a VR helmet nor AR glasses. This hybrid virtual reality device holographically projects computer-generated 3D virtual objects into real space, and the wearer of Hololens can interact with 3D virtual animation in real space and trigger corresponding functions. The imaging principle of this kind of MR equipment is different from that of immersive VR equipment. It projects virtual images into real space, but the imaging effect of the projected holographic 3D images breaks through the boundary between virtual and real world.

　　Research and Application of Virtual Reality Technology

　　The focus of NASA’s research on this technology is the real-time simulation of space station manipulation, and they use a lot of cockpit-oriented flight simulation technology. Such as the simulation of the Hubble Space Telescope and the experimental plan of "Virtual Planet Exploration", this project enables the "Virtual Explorer" to use the virtual environment to explore distant planets, and the first goal is Mars.

　　The University of North Carolina is the earliest and most famous university to study virtual reality technology. Their main research includes molecular modeling, aviation driving, surgical simulation, architectural simulation and so on. On the display technology, the university has developed a parallel processing system called Pixel Plane, which helps users to build real-time dynamic display in complex scenes.

　　MIT was originally a pioneer in studying artificial intelligence, robotics, computer graphics and animation. These technologies are the basis of virtual reality technology. In 1985, a media laboratory was established to conduct formal research on virtual environment.

　　The laboratory of man-machine interface technology in Washington Technology Center of the University of Washington plays a leading role in the research of new concepts, and is also conducting research on sensory, perceptual, cognitive and motor control abilities. They introduced the research of virtual reality technology into the fields of education, design, entertainment and manufacturing. For example, Boeing’s V22 transport plane was built in the laboratory before it was put into production.

　　Illinois State University has developed a distributed virtual reality technology system that supports remote collaboration in vehicle design. Engineers from different countries and regions can design in real time through computer networks. In the process of designing a vehicle, various components can share a virtual environment, and can view the video transmission and corresponding positioning direction of any position of the other party. Virtual prototype is adopted in the system, which reduces the time for designing images and new products to enter the market, so that products can be estimated and tested before production, and the quality of products is greatly improved.

　　George Mei Sen University has developed a real-time fluid simulation system in a dynamic virtual environment. In a distributed interactive simulation system, the physical characteristics of complex fluids in the real world are simulated, including simulating ships running across the water, stirring liquids, mixing liquids of different colors, and the influence of rain on the terrain.
