1. 什么是元宇宙

1992年，当美国著名科幻大师尼尔·斯蒂芬森在其科幻小说《雪崩》中提出“元宇宙”这个概念时，人们或许不会想到，他在书中设想的未来情境(人类通过虚拟现实设备与虚拟人共同生活在一个虚拟空间中)会走进现实，并借助科技大佬马克·扎克伯格的声明“一举成名”。
扎克伯格向美国媒体宣布，他认为“元宇宙”是下一代互联网，脸书拟在5年内转变为一家“元宇宙”公司。西班牙消息网在近日的报道中指出，除脸书外，其他互联网巨头近期纷纷布局“元宇宙”概念，未来人们或可身临其境般进入到一个虚拟的“元宇宙”世界。
美国彭博社称，“元宇宙”的市场规模将在2024年达到8000亿美元，到2030年或将达到2.5万亿美元。
什么是“元宇宙”
想象存在一个与现实世界平行的世界，一个数字“我”作为物理“我”的“分身”在其中交友嬉游、工作娱乐，一切都以沉浸的方式进行，使人们在这个平行世界中的互动与现实生活中尽可能相似，这就是“元宇宙”。
西班牙技术、艺术和设计学院的扩展现实专家劳拉·拉亚说：“‘元宇宙’指在网络空间中创建物理环境的数字‘分身’。它不以玩游戏和赚积分为目的，而将是一个数字现实，我们将在其中重现日常生活中的许多社会动态。它的另一个特点是沉浸感。”
一旦进入“元宇宙”，那里的居民将能够买卖物品、财产等。拉亚强调说：“如果你不能做现实世界中做的几乎所有事，那将只是一个普通的数字应用程序，但‘元宇宙’不是这样。虚拟货币在‘元宇宙’中必须存在”。换句话说，“元宇宙”将产生经济活动。
Gamelab战略顾问兼创始人伊万·费尔南德斯·洛博则表示：“‘元宇宙’的支柱之一是我们当前所有资产都被数字化并成为那个世界的一部分，就像在‘元宇宙’中所做的一切或发生的事情都可以某种方式进行交易，并产生一定的价值一样。区块链技术为这些问题如何发展提供了线索。”
与互联网一样，“元宇宙”将是一个由不同公司组成的协作生态系统，具有类似于万维网的开放标准，用户可以在其中自由地从一个平台移动到另一个平台，同时维护自己的数字资产。扎克伯格似乎是这种模式的推崇者。他说：“‘元宇宙’的美好愿景不是由哪家特定公司构建的，它必须具有互操作性和可移植性。”
不过，他的想法也遭到了一些怀疑。加泰罗尼亚开放大学计算机科学、多媒体和电信教授塞萨尔·科科莱斯指出：“在我看来，这似乎是‘元宇宙’向前发展的最佳方式，但这种方式出自一个商业模式与之截然相反的人之口令我大跌眼镜。”
亿万富翁们的“赌场”
尽管脸书最有能力开拓未来的虚拟空间——它拥有市场上最畅销的虚拟现实眼镜Oculus，但竞争仍将非常激烈。拉亚说：“脸书在生成虚拟形象和逼真的图形环境方面拥有强大的技术能力。但在其他方面，面临来自很多科技巨头的竞争。”
今年8月，脸书公司发布了Horizon Workrooms，允许用户在虚拟现实环境里举行会议。Epic游戏公司出品了Fortnite等热门游戏，4月从包括索尼在内的一群投资者那里筹集了10亿美元，用于创建自己的“元宇宙”。微处理器制造商英伟达已经有了一个面向工业领域的平台Omniverso，宝马等公司用其来对现实世界进行高级模拟。
洛博说：“脸书、微软、苹果、谷歌或亚马逊等科技巨头已经投入大量资源来概念化‘元宇宙’并创建必要的基础设施，从而在技术上支持‘元宇宙’梦想。他们依靠在视频游戏领域积累的知识、才能和技术来做到这一点，迄今为止，靠近‘元宇宙’的主要方法是视频游戏。”
实现仍面临不少挑战
尽管Fortnite或Roblox等全球热门游戏中包含“元宇宙”的元素，但要使其全面运行还需要很长的时间。西班牙卡斯蒂利亚-拉曼恰大学教授约瑟·安吉尔·奥利瓦斯说：“在上世纪60年代和70年代，人工智能先驱们说，15年后机器人将完成一切，但事实并非如此。‘元宇宙’领域也面临这种情况。尽管它不断在发展，但离我们还很远，因为有一部分需要进行很大改进。比如，如果我们想在‘元宇宙’中进行视频会议，就需要更好的通信，比如5G甚至6G通信，但现在要实现这些还有待时日。此外，可能还存在计算问题。”
另一个挑战在于虚拟现实设备需要改进。拉亚说：“脸书和苹果都已经宣布了他们的下一代眼镜，一两年后这些眼镜会变得更舒适、更实惠。”
他警告说：“而且，构建更好的‘元宇宙’还需要大量人才。如果没有人能够在虚拟现实中编程、开发和设计，‘元宇宙’就不会出现。而公司之间相互协作实现标准化，将是耗时最多的部分。”
科科莱斯则强调了公司项目适应用户偏好的重要性。他解释说：“脸书的‘元宇宙’尽量模仿现实，这有积极的一面，但将一切都转换到虚拟现实世界并不一定是一个好主意。除了涉及的经济成本外，首次访问‘元宇宙’的人可能很不习惯。随着越来越多人进入‘元宇宙’，以及相关研究越来越多，或许公司会进行较大调整以适应更多人的偏好。”
当然，研究人员指出，在经历了大流行之后，社会对“元宇宙”的接受度会更高，因为“大流行使我们更好地了解了技术在我们世界中的价值，远程呈现是‘元宇宙’对我们的极大诱惑。”
专家认为，在扎克伯格提到的5年中，“元宇宙”的应用将仅限于技术科学、工作和休闲领域。此时此刻，硅谷巨头们正为了成为第一批征服“元宇宙”的先驱而争相拿出支票簿，但这将是下一场技术革命还是只是像游戏《第二人生》那样被遗忘的虚拟空间，我们拭目以待。

2. 元宇宙是什么梗

指沉浸式的虚拟世界，英文Metaverse。这个虚拟世界由VR（虚拟现实）、AR（增强现实）等3D技术和互联网组成。用户可以在元宇宙中感受不一样的人生，或是体验与真实世界完全不同的世界。与现有网络游戏不同的是，元宇宙能给玩家带来更真实的感受，让玩家可以仿佛置身于虚拟世界当中，甚至可以做到无法区分真实与虚拟世界。元宇宙也被吹捧成了互联网的终极形态。电影《黑客帝国》和《头号玩家》就是元宇宙概念。元宇宙一词最早出自美国科幻小说《雪崩》。小说中描绘了一个与现实世界平行的虚拟世界，元界（Metaverse）。

3. 元宇宙用在3D打印传输企业

摘要国内3d打印技术研究起步早，从90年代起，核心技术具有先进一面，其处于领先地位科研机构主要为一些高校以及高校相应的企业化单位，这些单位生产的3d打印设备一般为工业级设备。

4. 什么是元宇宙概念

元宇宙是一个空间维度上虚拟而时间维度上真实的数字世界；从真实性来看，元宇宙中既有现实世界的数字化复制物，也有虚拟世界的创造物。

从独立性来看，元宇宙是一个与外部真实世界既紧密相连，又高度独立的平行空间；从连接性来看，元宇宙是一个把网络、硬件终端和用户囊括进来的一个永续的、广覆盖的虚拟现实系统。

起源

元宇宙（Metaverse）一词，诞生于1992年的科幻小说《雪崩》，小说描绘了一个庞大的虚拟现实世界，在这里，人们用数字化身来控制，并相互竞争以提高自己的地位，到现在看来，描述的还是超前的未来世界。

关于“元宇宙”，比较认可的思想源头是美国数学家和计算机专家弗诺·文奇教授，在其1981年出版的小说《真名实姓》中，创造性地构思了一个通过脑机接口进入并获得感官体验的虚拟世界。

5. 元宇宙的含义是什么

元宇宙主要指的是虚拟世界。

元宇宙是一个相对比较抽象的概念，目前我们并没有对元宇宙进行精准定义。从某种意义上来讲，我们所能理解的虚拟世界的集合就是元宇宙。如果你难以理解这个概念的话，可以尝试理解现实世界，我们所有人都生活在现任世界。然而在精神和意识层面上，我们所进行的很多活动其实都是一个个独立的元宇宙。

一、什么是元宇宙？

元宇宙是虚拟世界的集合，这是后互联网时代的一个新名词，同时也是一个非常热门的概念。我不知道你有没有看过一部电影，这部电影的名字叫头号玩家。在这部电影中，主人公和身边的小伙伴所进行的战斗场面就是在元宇宙里进行，而在现实生活中，他们有着现实的身份，现实的身份并不影响元宇宙的身份。

6. 元宇宙是什么意思

结语

底层技术的迭代将引发互联网的变革，未来全球将逐步从移动互联网时代迈入元宇宙。因此，在元宇宙的大背景下，世界各国必将依托自身禀赋和优势进行全面布局以在国际竞争中占得先机。

1. What is the Metaverse

In 1992, when the famous American science fiction master Neal Stephenson proposed the concept of the "Metaverse" in his science fiction novel "Snow Crash", people You may not have thought that the future scenario he envisioned in the book (human beings living together with virtual people in a virtual space through virtual reality equipment) would come into reality, and with the help of technology tycoon Mark Zuckerberg’s statement “In one fell swoop Become famous".
Zuckerberg announced to the American media that he believes the "Metaverse" is the next generation of the Internet, and Facebook plans to transform into a "Metaverse" company within five years. Spanish News Network pointed out in a recent report that in addition to Facebook, other Internet giants have recently laid out the concept of "metaverse". In the future, people may be able to enter a virtual "metaverse" world as if they were there.
Bloomberg of the United States stated that the market size of the “Metaverse” will reach US$800 billion in 2024, and may reach US$2.5 trillion by 2030.
What is the "Metaverse"
Imagine that there is a world parallel to the real world, where a digital "I" serves as a "clone" of the physical "I" where I can make friends, play, work and play, and everything is based on It is carried out in an immersive way so that people's interactions in this parallel world are as similar as possible to real life. This is the "Metaverse".
Laura Laya, an extended reality expert at the Spanish Institute of Technology, Art and Design, said: "The 'Metaverse' refers to the creation of digital 'doppelgangers' of physical environments in cyberspace. It is not about playing games and earning points. The purpose, instead, will be a digital reality in which we will recreate many of the social dynamics of everyday life. Another feature of it is immersion."
Once in the "metaverse", residents there will be able to buy and sell Items, property, etc. "If you couldn't do almost everything you do in the real world, it would be just an ordinary digital application, but that's not the case in the Metaverse. Virtual currencies must exist in the Metaverse," Raya emphasized. In other words, the "metaverse" will generate economic activity.
Gamelab strategic advisor and founder Ivan Fernandez Lobo said: “One of the pillars of the Metaverse is that all of our current assets are digitized and become part of that world, just like in the Metaverse 'Everything done or happening in the Internet can be traded in some way and generate a certain value. Blockchain technology provides clues to how these issues develop."
Like the Internet, the "Metaverse" "It will be a collaborative ecosystem of different companies with open standards similar to the World Wide Web, where users can move freely from one platform to another while maintaining their digital assets. Zuckerberg seems to be an advocate of this model. He said: "The beautiful vision of the 'Metaverse' is not built by any specific company, it must be interoperable and portable."
However, his idea has also been met with some skepticism. Open University of Catalonia Computer Science"This seems to me to be the best way for the Metaverse to move forward, but it comes from a business model that is diametrically opposed to it," said Cesar Kokoles, professor of science, multimedia and telecommunications. I was stunned by the human mouth.”
The “casino” of billionaires
Although Facebook is best positioned to open up the future of virtual space-it owns the best-selling virtual reality glasses Oculus on the market, Competition will remain fierce. Raya said: "Facebook has strong technical capabilities in generating virtual images and realistic graphical environments. But in other aspects, it faces competition from many technology giants."
In August this year, Facebook released Horizon Workrooms, allows users to hold meetings in a virtual reality environment. Epic Games, the maker of popular games such as Fortnite, raised $1 billion in April from a group of investors including Sony to create its own "metaverse." Microprocessor maker Nvidia already has an industrial platform, Omniverso, which companies like BMW use to perform advanced simulations of the real world.
Lobo said: “Tech giants such as Facebook, Microsoft, Apple, Google or Amazon have invested significant resources in conceptualizing the Metaverse and creating the necessary infrastructure to technically support the Metaverse dream. They do this by relying on the knowledge, talent and technology they have accumulated in the field of video games, and to date, the main way to approach the 'Metaverse' has been video games."
There are still many challenges to implementation
Although Globally popular games such as Fortnite or Roblox contain elements of the Metaverse, but it will take a long time to make them fully operational. Jose Angel Olivas, a professor at the University of Castile-La Mancha in Spain, said: "In the 1960s and 1970s, artificial intelligence pioneers said that in 15 years robots would do everything, but that was not the case. The field of 'Metaverse' is also facing this situation. Although it is constantly developing, it is still far away from us, because some parts need to be greatly improved. For example, if we want to conduct video conferencing in the 'Metaverse', then Better communications are needed, such as 5G or even 6G communications, but it will take time to achieve these now. In addition, there may be computing problems.”
Another challenge is that virtual reality equipment needs to be improved. "Both Facebook and Apple have announced their next generation of glasses, which in a year or two will become more comfortable and more affordable," Raya said.
"And, building better ones," he warned. The 'Metaverse' will also require a lot of talent. If there are no people who can program, develop and design in virtual reality, the 'Metaverse' will not happen. And the collaboration between companies to standardize will be the most time-consuming part."
Kokoles emphasized the importance of adapting the company's projects to user preferences. He explained: “Facebook’s ‘Metaverse’ tries to imitate reality as much as possible, which has a positive side, but it converts everything into virtual reality.Simulating the world is not necessarily a good idea. In addition to the financial costs involved, visiting the ‘Metaverse’ for the first time can be quite unaccustomed. As more and more people enter the ‘Metaverse’ and more and more related research is conducted, perhaps the company will make major adjustments to accommodate more people’s preferences. ”
Of course, the researchers noted that society will be more receptive to the Metaverse after experiencing the pandemic because “the pandemic has given us a better understanding of the value of technology in our world, Telepresence is the great temptation that the 'Metaverse' has for us. ”
Experts believe that in the 5 years mentioned by Zuckerberg, the applications of the “Metaverse” will be limited to the fields of technology, science, work and leisure. At this moment, Silicon Valley giants are trying to become the first batch of Pioneers of the metaverse are scrambling to get their checkbooks out, but whether this will be the next technological revolution or just a forgotten virtual space like Second Life remains to be seen.

2. What is the metaverse?

It refers to the immersive virtual world, Metaverse in English. This virtual world is composed of 3D technologies such as VR (virtual reality), AR (augmented reality) and the Internet. Users can Feel a different life in the universe, or experience a world completely different from the real world. Unlike existing online games, the Metaverse can bring players a more realistic experience, allowing players to feel as if they are in a virtual world. It can even be impossible to distinguish between the real and virtual worlds. The metaverse has also been touted as the ultimate form of the Internet. The movies "The Matrix" and "Ready Player One" are the concept of the metaverse. The term metaverse first came from the American science fiction novel "Snow Crash" . The novel depicts a virtual world parallel to the real world, the Metaverse.

3. Metaverse is used in 3D printing transmission companies

Abstract Domestic 3D printing technology research It started early. Since the 1990s, the core technology has been advanced. Its leading scientific research institutions are mainly some universities and corresponding enterprise units of universities. The 3D printing equipment produced by these units is generally industrial-grade equipment.

< p>4. What is the concept of metaverse

The metaverse is a digital world that is virtual in the space dimension and real in the time dimension; from the perspective of authenticity, there are digital replicas of the real world in the metaverse , there are also creations of the virtual world.

From the perspective of independence, the Metaverse is a parallel space that is both closely connected to the external real world and highly independent; from the perspective of connectivity, the Metaverse is a A sustainable and wide-coverage virtual reality system that includes networks, hardware terminals and users.

Origin

The term Metaverse was born in the 1992 science fiction novel "Snow Crash". The novel depicts a huge virtual reality world, where people use digital avatar to control,And compete with each other to improve their status. Up to now, it seems that the description is still an advanced future world.

As for the "Metaverse", the more recognized source of thought is the American mathematician and computer expert Professor Verno Vinci, who creatively conceived the idea in his 1981 novel "Real Names" A virtual world that can be entered and experienced through brain-computer interfaces.

5. What is the meaning of the metaverse?

The metaverse mainly refers to the virtual world.

The Metaverse is a relatively abstract concept. Currently, we do not have a precise definition of the Metaverse. In a sense, the collection of virtual worlds we can understand is the metaverse. If you have trouble understanding this concept, try understanding the real world we all live in. However, at the spiritual and conscious level, many of the activities we perform are actually independent metaverses.

1. What is the Metaverse?

The metaverse is a collection of virtual worlds. This is a new term in the post-Internet era, and it is also a very popular concept. I don't know if you've ever seen a movie called Ready Player One. In this movie, the battle scenes between the protagonist and his friends take place in the metaverse. In real life, they have real identities, and their real identities do not affect the identity of the metaverse.

6. What does the Metaverse mean?

The meaning of the Metaverse is:

The word Metaverse was born in the 1992 science fiction novel "Metaverse" "Avalanche", the novel depicts a huge virtual reality world, where people are controlled by digital avatars and compete with each other to improve their status. Up to now, it seems that the description is still an advanced future world.

Therefore, if digital technology giants with multiple advantages want to hold on to the market, and if start-ups in the digital technology field want to gain the opportunity to overtake in corners, they must plan in advance or even increase the number of tracks in the metaverse.

8. What are the advantages of the world's top three economies in laying out the "Metaverse"

1. Rich animation IP resources

In March 2020, Nintendo released the seventh work in the "Animal Crossing" series. Like the previous "Animal Crossing" series, each user occupies a desert island and can visit other users' islands. ; You can design your own clothes, signboards and other props.

2. Application scenarios continue to expand

On August 5, 2021, Avex Business Development and Digital Motion established Vitual Avex, planning to promote existing animation or game characters, hold virtual artist events, and virtualize events such as real artist concerts. In addition, extending from application scenarios such as entertainment, Japan has currently applied corresponding technologies in fields such as performances and conferences.

Conclusion

The iteration of the underlying technology will trigger changes in the Internet. In the future, the world will gradually move from the mobile Internet era into the metaverse. Therefore, in the context of the metaverse, countries around the world will rely on their own endowments and advantages to make comprehensive arrangements to take advantage of international competition.
