为什么日本7-11这么能打？
IEEE全球元宇宙大会由IEEE标准协会主办，包括一系列峰会（线上或线下线上结合），旨在提供关于元宇宙的全球和全面的视野。大会网站为metaverse.ieee.org。
IEEE全球元宇宙大会系列峰会之7月9日中国站的主题为“元宇宙及其在中国的快速发展（The Metaverse and Its Rapid Growth in China）”。全部录制视频及文字整理将作为“精彩回顾”系列陆续发布。本期“精彩回顾”的内容是：
Opening Remarks by Konstantinos Karachalios (Managing Director, IEEE Standards Association)
开幕致辞 - Konstantinos Karachalios (IEEE标准协会秘书长)
中文译文
谢谢亲爱的袁昱，谢谢你邀请我参加此次面向中国专家的活动。
首先，我很高兴看到来自工业界和学术界的专家对IEEE的活动越来越感兴趣。我特别高兴地看到，不仅参加者和项目数量在飙升，而且这些项目的高质量和复杂度也让人印象深刻。
例如，虽然算法系统的联邦学习的想法最初是由美国专家构思和推广的，但中国工业界在IEEE发起并已经完成了部分相关的标准化项目。
总的来说，我们看到来自中国的参与者为IEEE开放的、深度参与的系统带来的贡献，与来自世界各地的相关方公开分享关键新兴和高科技领域非常好的想法和概念，例如健康机器人、无人机、高速列车、人工智能系统、区块链等。
袁昱成功当选IEEE标准协会2023—2024届主席，是中国这个重要国家的又一个成功案例。据我所知，这是第一位来自北美以外的IEEE标准协会主席。
袁昱也是元宇宙领域的国际知名专家，这个新世界就交给他和其他专家来指导。在我看来，元宇宙既是远景，在某些方面也是现实，与正在成为许多行业和社会战略目标的数字化转型密切相关。
除了以实际结果为导向的数字化转型之外，元宇宙的爱好者还受到美学和某种叙事的驱动，他们希望将元宇宙视为一种无法区分的平行世界，甚至是与现实世界的叠加。
增强的物理世界是一个非常有趣的概念。但就我柏拉图式的口味而言，物理世界将永远比虚拟的任何版本都优越和可取。顺便说一句，虚拟世界可能比现实世界更快地变得功能失调。
在更实用的层面上，教育、健康、娱乐、远程工作、日常生活中的人工智能助手、工业流程的优化以及城市规划是数字化转型成功的一些显而易见的应用领域。很多事情已经发生，最近的新冠肺炎流行加速了这些过程。
为了迅速升级，并避免由垄断者造成的、可能使我们在最近的互联网时代的平台上经历的所有反乌托邦事件都相形见绌的不良锁定效应，开放和透明而不是由公司私有的标准将必不可少。
IEEE正在提供其标准化流程和所有必要的支持，以便在这一非常重要的前沿取得进展，我们很高兴地看到多个团体，包括来自中国的团体，与IEEE合作的热情与活力。
在结束之前，我想就虚拟现实环境作为任何元宇宙的构成要素之一的一个非常重要的方面提供我的评估标准。
构建任何虚拟现实环境的关键成功标准是现实世界的参与者，我或你，无法轻易地将其与物理世界区分开来。
除了模拟嗅觉、味觉和其他直接或间接的刺激等远远还没实现的特性之外，在我看来，最高质量的视觉和虚拟对话似乎是首先要实现的重要目标。
由于技术挑战和限制，我相信实现无法与现实世界区分的视觉模拟非常难以快速实现。
然而，在虚拟对话（例如聊天机器人）面前，情况有所不同。在我看来，一些公司已经创建了可以与人类对话者（口头或书面）交互的机器人，很快通过对话就很难将机器人与另一个人区分开来。当然，除非你问机器人是人还是机器人，并且被指示不要在这个问题上撒谎。这意味着，图灵测试可能已经失去了它的用处。所以，不管它的价值是多少，元宇宙的这个维度已经存在，不再是科幻小说了。
我的致辞到此结束，祝愿大会取得圆满成功。
英文原文
Thank you, dear Yu Yuan, for your kind invitation to welcome the participants of this event, which is targeted at Chinese experts.
First of all, I would like to take a step back and express my great pleasure for experiencing an increased and sustained interest by Chinese experts from industry and academia in IEEE’s activities.
I am particularly pleased to see that it is not only the numbers of participants and projects that are soaring; the high quality and degree of sophistication of the projects are very remarkable.
As an example, while the idea of federated learning for algorithmic systems was initially conceived and promoted by experts in the US, it was Chinese industry that initiated, and partly accompliced, related standardization projects at IEEE.
Generally, we see that participants from China bring to the open, deeply participatory systems of IEEE, and thus share openly with interested parties from all around the world, very good ideas and concepts in key emerging and high-tech areas, such as health robotics, UAVs, high speed trains, AI systems, block chain, etc.
The election of Yu yuan as the SA President for the years 2023-2024 (as far as I know, the first IEEE SA President outside of North America), is another element of IEEE SA’s success story of engagement in this important region of the world.
Yu Yuan is also an internationally renowned expert in Metaverse matters, so I will leave it to him and the other experts to guide you through this emerging world. From my perspective, Metaverse is both a long-term vision and a reality in certain aspects, closely related to the digital transformation which is becoming a strategic goal for many industries and societies.
Beyond a practical results-oriented digital transformation, the afficionados of Metaverse are driven by esthetics and a certain narrative, that would like to see Metaverse as an indistinguishable juxtaposition, even a superposition to the real world.
An augmented physical world is a very intriguing concept, but for my Platonic taste, the physical world will always be infinitely superior and preferable to any version of the virtual, which, btw, may become dysfunctional faster than reality.
At a more pragmatic level, education, health, entertainment, remote working, myriads of little AI assistants in our everyday life, and optimization of industrial processes as well as urban planning are some of immediately evident application areas of a successful digital transformation. A lot is already happening, and the recent waves of the pandemic have accelerated these processes.
For a rapid escalation and in order to avoid undesired lock-in effects by dominant players that may dwarf all dystopias we have been experiencing from the platforms of the recent Internet era, open and transparent - not company proprietary - standards will be essential.
IEEE is offering its standardization processes and all necessary support in order to make progress at this very essential front, and we are happy to see the enthusiasm and energy of several communities, including from China, who are engaging with us.
Before I conclude, I would like to offer you my assessment about where we stand with respect to a very essential aspect of the realization of virtual reality environments as one of the constitutional elements of any Metaverse.
The key success criterion for the construction of any virtual reality environment is that the real world participant, me or you, cannot easily distinguish it from the physical world.
Beyond still far away features such as smell, taste and other direct or indirect stimulations of our brain by simulated experiences, highest quality of optical illusion and of virtual interlocutors seem to me to be the first important targets to be achieved.
Because of technical challenges and limitations, I believe it will be very difficult to achieve any time soon optical illusions that will be indistinguishable from the real world.
However, at the front of virtual interlocutors (e.g., chatbots) things are different. In my opinion, some companies have already created bots that can interact with a human interlocutor (orally or in writing) in a way that is impossible to distinguish the bot from another human. Unless, of course, you ask the bot whether it is a human or bot and it is instructed not to lie wrt this question. This means, the Touring test has probably lost its usefulness. So, for whatever it is worth, this dimension of the Metaverse is already there, it is not science fiction anymore.
With this, I conclude my welcome address to you and I am wishing you a very successful seminar.
关于元宇宙
元宇宙（Metaverse）是引起大众关注的最新未来技术趋势。30年前，Neal Stephenson 在其科幻小说《雪崩》中创造了“metaverse”一词以概括他笔下的虚拟现实。48年前，Steve Mann发明了基于可穿戴计算的扩展现实技术，并将其称为“metavision”。从词源出发并兼顾其内涵和外延伴随技术进步的合理拓展，元宇宙是关于外界被用户（人类或非人类）感知为一个实际建立在数字技术之上的宇宙的一种体验，这个宇宙或者是与我们当下的宇宙不同的宇宙（“虚拟现实”），或者是我们当下的宇宙的一种数字扩展（“增强现实”或“混合现实”），或者是我们当下的宇宙的数字对应物（“数字孪生”）。元宇宙既然以宇宙命名，就必须是持久的，而且应该是巨大的、全面的、沉浸的、自洽的。元宇宙既然用“meta”来形容，就应该是逼真的、易用的、泛在的，并且可以是去中心化的。狭义上，元宇宙可以简单地定义为持久存在的虚拟现实（PVR）。广义上，元宇宙是数字化转型的高级阶段和长期愿景。
今天，元宇宙就像一个有魔力的词，激发了无数来自不同行业和背景的人的无限想象。不同的人眼里有不同的元宇宙，但迄今为止关于元宇宙的最大共识是，它将对我们的日常工作、娱乐和生活产生深远的跨越各行各业的影响，重塑全人类的经济和社会。
