Yuan universe is a what? Listen to co-workers to decode Professor

Recently, the concept of the universe yuan fire. Foreign and domestic Internet companies, technology companies actively layout, have entered the relevant fields. Yuan universe has become a hot topic in the scientific community, to circle the streets of the capital.

What is the dollar universe? Its present and future of the world may have any effect? Today, the official micro invited Software Institute Professor Xue, you decode "hot" meta-universe.

History and current situation of the universe yuan

English yuan universe is Metaverse, Meta said, "Yuan", verse represents the "universe". This concept is based on a parallel Stephenson’s novel "avalanche" depicted in the virtual reality world of digital world – "put on headphones and eyepiece, find the connection terminal, will be able to enter a virtual avatar of the way by a computer simulation, and real parallel virtual world space. "

This idea has a strong sci-fi color are now virtual reality, social gaming, artificial intelligence technology giant mining company, and become a popular technology concept this year, the capital has become a hot chase.

March 2021

It is called "meta-universe" Roblox first unit was successfully listed on the New York Stock Exchange, which is also recognized as the starting point for this year yuan outside the concept of the universe outbreak.

Yuan universe far away from us (Economic Times)

"Meta-universe" Although attracted enthusiastic attention, but can really bring about a new round of industrial revolution, but also objective analysis, careful judgment.

The core elements of the universe and challenges yuan

Yuan essence of the universe can be seen at two levels:

The first level, from a development perspective sequential technology, industry point of view, at this stage yuan universe is more like an enhanced version of virtual reality, its technical form dependency modeling of virtual worlds, virtual human-computer interaction technology, its application scenarios dependence virtual role-playing games.

The second level, from a giant company and capital to promote the vision of view, the essential mission yuan universe is to re-model a new virtual world, then there must be a lot of reconstruction required elements, which can anticipate a flood of opportunities exist – this is also the reason for these tech giants are willing to invest heavily.

So, the core elements yuan universe, what does?

Technical elements

Virtual reality is one of the basic technical metadata universe, visual, hearing, touch and even smell and other senses extent of coverage of the universe is real or not important yuan mark, and related products industry in these years and not showing a trend of vigorous development, virtual headset is facing such a portable device is not enough, the lack of natural interaction and feedback tools, vision and action by the many challenges bound, dizziness and other users need to be addressed, in order to constitute a support for the dollar universe of technology still has a long way go. Meanwhile, 5G also support the development of the universe yuan basic technology, in order to achieve synchronization in parallel with the actual situation of the binary world, vast amounts of data transfer operations are essential aspects of our technology in leading 5G provides a good storage elements. Artificial intelligence is another important need to rely on the technology yuan universe, if you want the virtual world and the real world as prosperous rich, and to face the real world of humans to understand the real world, people do all kinds of brain structure based on the judgment made, forecast, which is the core mission of artificial intelligence. AI research is currently in full swing in the dollar universe from the real mature, prosperity before should not constitute a technical bottleneck.

Content elements

To construct meta description prosperous universe virtual world scene, the contents of the virtual character design configuration is another important element in addition to the technical elements. This space is facing great difficulties: Interactive actual situation of duality is the highest demand for yuan universe, if not meet this functional requirement, finally falling to sensory stimulation targeted virtual game level cliche, but to participants in the universe for each one yuan, two yuan experience who realize the actual situation of the interactive space and mapping, scenario, content design, production, real-time updates will be a huge challenge. So, for the foreseeable future, the development of the universe result yuan is likely to be the local scene, the local universe yuan period, local activities, and it is difficult to form a logical sequence relationship, such as cause and effect between these "local", is still an independent virtual reality applications.

Human Factor

Novel "avalanche" in the description of the yuan spirit of the universe is actually one kind CyberPunk (cyberpunk) conception, characters in the novel embodies a sense of rebellion and escape, to perform another world in cyberspace (CyberSpace) exploration. Now society, may be part of a virtual character in the game, although players to entertainment, leisure original intention to participate, but there are a considerable number of players is because in the real world does not look the part, the lack of full fighting spirit, and even into a high-tech low life kind of decadence. So entertainment, social property accounted for oversized yuan to promote universe if excessive, over-development, there may be with positive energy, not quite matching the theme of the issue is the community, especially in the face of government level requires careful, there is also a need for society as a whole kind of humanistic nature of the atmosphere, mechanisms to guide and encourage.

The opinions and recommendations


Yuan universe focused on the short term

Online games, virtual reality and other interactive applications

Yuan universe, all sectors are currently no definition of a precise meaning. Although the first practitioners such as Facebook, beating bytes, Tencent and other domestic yuan for the ultimate description of the universe yuan universe is very ambitious, but from the perspective of technology development and technology can achieve in the future visible point of view, more like a traditional virtual reality converged applications and social networking applications, it is not a from there to, from zero to a concept and industry, a vision but a high degree of integration of existing technologies, and external performance can only be a short-term network games, virtual social networking, virtual electricity providers and other traditional application-based.

Development prospects of the universe can not be blindly optimistic yuan

Some people predict will be the next generation of the Internet universe yuan, with a modern digital subversion of the potential economic landscape the grounds that the AR / VR glasses is about to be popular next-generation mobile computing platforms, and the Internet industry yuan universe is presented on this new platform. Personally I feel that this view is too optimistic, and there are two key points:

First, as a meta-universe strongly dependent on infrastructure AR / VR headset is not yet mature, a short time is difficult to support large-scale development of the universe yuan. AR / VR headset as the most typical display and interactive virtual reality technology equipment, made from twenty years has not been long since the short break the bottleneck caused by the use of the user dizziness, and this is virtual reality technology these years have not been the main reason for the rapid development (although there have been one or two middle outlet become hot short scene).

Second yuan universe there are a lot of applications in the real world be aware, reconstruction and enhancement tasks, is up-dimensional virtual world to the real world, this process is important to detect, identify, 3D reconstruction, mathematical modeling process basically by hand realize that the current hot artificial intelligence technology, to provide yuan universe of perception of the world a promising way, but limited force count, still fall short fine perception level.

Therefore, the actual situation in the short term in order to achieve full synchronization effects meta-universe is not possible, the expected dollar universe can only be degraded to the local scene, local time, topical application of "point-like" actual situation sync, and the reality of this partial synchronization it is some modern virtual reality applications or upgrade its limited edition, stay in the gradual quantitative stage, it is difficult to achieve the desired effect led to the formation of a strong track. Though not happen overnight, but based on the current concern about the breadth of style can be expected once the outbreak of related technologies, verification and integration, the researchers in this field is a rare opportunity.


A reasonable guide the industry and the public’s attention

The current meta universe is mainly sponsored by the Internet giant in the field of social networking, games, and other electricity providers, can be considered after the concept of virtual reality, 5G, chain blocks, artificial intelligence and other related businesses ahead of the layout of the respective hardware and software technologies and resources the concept of integration, the occupation of the initiative. Fame and fortune in itself is an understandable business practices, but technology in over-conceptualized under the operating capital, entertainment, not necessarily conducive to the development of its own. Without occupying too much public resources, does not lead to excessive waste of human resources, does not bring significant indulge virtual space and other social issues, we expect the dollar to 100 cents universe, you might get 70-80 points harvest, but also not a bad idea to explore and choices.

Carried a pink ball in my kit bag for last three months, don’t know why: Mandhana

India opener Smriti Mandhana familiarised herself with the pink ball by keeping one in her kit bag for the last three months, looking at it on and off while trying to “understand” it.

When the idea struck her, little did Mandhana know that her team would enter its first-ever day/night Test match with just two days of training sessions with the pink ball.

The idea to keep the coloured ball around her worked well for the stylish player, who was batting on a sublime 80 when inclement weather brought an early end to the opening day of their historic Test, against a formidable Australian side here.

India opener Smriti Mandhana familiarised herself with the pink ball by keeping one in her kit bag for the last three months, looking at it on and off while trying to “understand” it.

When the idea struck her, little did Mandhana know that her team would enter its first-ever day/night Test match with just two days of training sessions with the pink ball.

The idea to keep the coloured ball around her worked well for the stylish player, who was batting on a sublime 80 when inclement weather brought an early end to the opening day of their historic Test, against a formidable Australian side here.

“We just had two sessions with pink ball. I was coming from the Hundred (in England) so I didn’t really get much time to play with pink ball, but during Hundred, I just ordered a pink kookaburra ball, just to keep it in my room because I knew that there is going to be a Test match, so that I can just look at the ball and understand.

“I have actually not batted, I batted for just two sessions but the pink ball was there in my kit bag for last two and half, three months. I don’t know why did I carry it, I thought I will have a session but I really didn’t get time to do that,” Mandhana said during a virtual press conference on Thursday.

Mandhana headlined a rain-hit opening day with a career-best knock which had elegance written all over it as the Indian women’s cricket team finished on 132 for 1.

Speaking further on her preparation for the pink ball Test, she said, “I don’t think we had a lot of time to work regarding this, we are just trying. People who are sitting out really helped, they kept me pumped up throughout the day, they contributed in making me focus in the way I did today,” Mandhana said.

The Indian star said her plan was to just play as per merit and not over complicate things.

“I wanted that I just don’t look at the scorecard, was just trying to be as blank and simple, play according to the ball. I didn’t really plan anything.

“Last two days I felt good, felt I was able to bat well. I will try and do that tomorrow because I don’t want to complicate things.”

She is also not thinking about a century, focussing only on batting as well as she can to help the team notch up a good first-innings score.

“Not thinking about triple figure at the moment, the team needs me to bat well and in the process If I get one… I am just watching the ball and reacting.”

Mandhana is relishing being part of a multi-format tour of a tough cricket-playing nation such as Australia.

“I am loving this multi format series, go and bat with few slips and gully so you have to apply yourself, that really tests you.. You have to focus .. switch on and switch off,” she said.

“Test cricket is always about different challenges and we would always want to play as may Tests as possible.”

Hosts Australia decided to put India in to bat after winning the toss but did not enjoy a good start to the game.

“They bowled slightly short in the first 15 overs but made up in the latter stages.
We are used to batting first now but with the kind of wicket it looked like we also would have batted first. But, looking at the scoreboard now, we are happy to bat first.

“The openers have to step up and provide a good base whenever this kind of conditions come up,” Mandhana said.

A strong player on the back foot, Mandhana said batting on matting wickets in her early days contributed to it.

“I think with India being so vast we have different ways of growing up. I played a lot of cricket on matting till I was 15, it bounces a lot more on that.”

She lavished praise on her younger opening partner Shafali Verma (31), with whom Mandhana put on 93 runs for the first wicket.

“In England we had 150-odd run partnership. We just try and back each other, we have good conversations. She was really batting well on this wicket.”

Mandhana seemed to have slowed down in the latter stages of the day but that had nothing to do with the breaks brought on by lightning and rain.

“It was more to do with the field placements and not breaks.”

Australia skipper Meg Lanning admitted that her team could not make most of the conditions.

“I think we bowled a touch too short and allowed them to play a bit more on the back foot. We took a while to adjust to the conditions. We have got a good plan heading into tomorrow and just got to execute them,” Lanning said.

She praised Mandhana for showing “excellent temperament while hitting the bad balls and defending the good ones”.

“She has played extremely well so far, showed how to adapt to this format. But we feel we are still in the game.”
