Abstract
The Metaverse is a concept that is currently being developed for the future generation of the Internet. It aims to provide an autonomous, completely immersive, and spatiotemporal virtual community where people can work, play, and interact. Recent advancements in cutting-edge technology such as augmented reality, Artificial Intelligence, and blockchain are making the once-fantastical metaverse seem more like a plausible reality. This paper presents an in-depth analysis of the technologies utilized in the Metaverse, providing a solid foundation from which to further study this fascinating field. To be more specific, we look into the fundamental characteristics of a novel distributed metaverse architecture in terms of ternary-world interactions. The benefits and drawbacks of the metaverse are then explored, along with the current pressing problems that metaverse systems face and the most cutting-edge solutions to those problems. Finally, we propose new avenues for metaverse system development study.
Keywords: Augmented reality, artificial intelligence, blockchain, metaverse
1.1 Introduction
1.1.1 The Emergence of the Metaverse
The term "metaverse," which was first used by author Neal Stephenson in his science fiction novel Snow Crash, was first published in 1992 [1]. "Meta" comes from the Greek for "beyond," and "verse" means "universal." The novel depicted the metaverse as a virtual counterpart to the real world or a dystopian version of the internet. Shared term "metaverse" is also used to describe virtual worlds where users can enter as digital avatars and conduct business or social interactions with other users. The metaverse is intended to be an alternative to the World Wide Web that is more immersive. There have been several expansions of the Metaverse. In the late 1970s, text-based interactive games like MUD (Multi-User Dungeon) were released, depicting a multiplayer virtual environment with role-playing, interactive narrative, and online conversation. At the time, the term "Metaverse" didn't exist. These games might be considered the forerunners of the Metaverse. Commercial virtual worlds like Second Life were created during the post-millennial era, which marked the start of the second phase. After that, a fully virtualized 3D environment was approved, such as OpenSimulator, which is normally compatible with Second Life [2].
The metaverse is an ever-present, cooperative online environment where users can participate in interactive narratives. It combines several technologies, including Mixed Reality (MR), Virtual Reality (VR), Extended Reality (XR), Augmented Reality (AR), the Internet of Things (IoT), Artificial Intelligence (AI), Non-Fungible Tokens (NFTs), and Information and Communications Technology (ICT) infrastructure. The Metaverse is currently being developed by IT firms as the successor to the mobile Internet. The Metaverse will eventually surpass the Internet in terms of transforming new service ecosystems in all spheres of human endeavor, including healthcare, education, entertainment, e-commerce, and smart industries. The excitement surrounding the Metaverse is primarily driven by two factors. First off, the COVID pandemic has caused a paradigm shift in how people currently engage in work, entertainment, and socializing. As more individuals get used to doing these physical activities in virtual reality, the Metaverse will become necessary. Second, the Metaverse is becoming a more real prospect thanks to newly developed technical enablers [3, 32].
1.1.2 Core Attributes of a Metaverse
The basic characteristics of the Metaverse include:
Synchronous and live: The Metaverse will be a living experience for everyone, just like "real life," with pre-scheduled and self-contained events.
Persistent: It simply keeps going without ever pausing, restarting, or stopping.
Available individually and concurrently: Everyone can join the Metaverse and participate in an event, venue, or activity with their agency. In a well-functioning economy, people and corporations should be able to create, own, invest in, sell, and be reimbursed for many acts that create value. These actions include creating, selling, and being remunerated for goods and services.
An experience: All aspects of the user's environment, including online and offline spaces, closed and open systems, and public and private networks, should be considered [33, 71].
A wide range of contributors: There should be a wide variety of content and activities, with many different people (some of whom work independently, others for for-profit enterprises) involved [4].
Offer unprecedented interoperability: There needs to be seamless sharing of information, digital assets, content, and other elements throughout the various platforms; for instance, a car built for Rocket League (or even Porsche's website) may be adapted for use in Roblox. The way things work in the digital world of today is comparable to the way a shopping mall operates, with each establishment having its own money, ID cards, proprietary units of measurement for items such as shoes or calories, and separate dress requirements, among other things [5, 72].
1.1.3 Key Features of Metaverse
Infrastructure: Answers to the question "What are the key characteristics of the metaverse?" would emphasize infrastructure. In the context of the metaverse, infrastructure refers primarily to the technological infrastructure supporting the metaverse. In addition to utilizing high-tech components such as GPUs, the infrastructure consists of communication technologies such as Wi-Fi, cloud computing, and 5G. The continued expansion of the metaverse is one of its defining features. Therefore, the metaverse architecture must offer ultra-low latency, tremendously fast speeds, and expanded capacity [34, 35]. A robust infrastructure serves as the basis for smooth, value-based experiences for all metaverse users. Recent endeavors make the emphasis on infrastructure as a crucial entrance among metaverse elements abundantly clear. The ICT Ministry of South Korea laid the groundwork for an alliance between seventeen distinct enterprises and eight distinct industry organizations. To promote the growth of the metaverse ecosystem, the industry alliance offers crucial opportunities for enhancing the metaverse's infrastructure [6, 73].
Human Interface Technologies: When discussing infrastructure as one of the primary metaverse characteristics, it is natural to resort to human interface technologies. For joining the metaverse, users can utilize technology such as VR headsets, haptics, AR glasses, and many more. The human interface technologies aid in transferring users to the metaverse's endless immersive places. However, advances are being made to human interface technology for the metaverse. Smartphones, laptops, tablets, and personal computers can also function as metaverse access points when equipped with the necessary features [7, 74].
Digital Avatars: Avatars are a key feature among the significant characteristics of the metaverse. Digital avatars are one of the core components of the metaverse's design. Users can develop digital avatars for unconventionally expressing their thoughts and feelings in the metaverse. You can use the metaverse features to create personalized digital avatars, allowing you to create a digital version of your favorite superhero. Intriguingly, the ability to create and modify digital avatars in the metaverse also provides new opportunities for gamification. Consequently, digital avatars build the foundation for an engaging and immersive experience within the metaverse. Imagine 4.66 billion internet users creating digital avatars, exploring the metaverse, exchanging knowledge, and engaging with other avatars. Isn't this a truly revolutionary experience?
Decentralization: Decentralization would be the second most prominent response to the question, "What are the key characteristics of the metaverse?" The metaverse is envisioned as an open, shared reality in which users can travel fluidly between platforms. Users of the Metaverse might generate their own virtual experiences and assets with monetary worth and sell them without the need for centralized authorities [37]. This is where decentralization, a prominent aspect of the metaverse, would be found. Some of the most important technologies promoting the democratization of the metaverse are blockchain, edge computing, and AI [8]. Users can obtain complete control and ownership over their assets and experiences in the metaverse through decentralization. Consequently, the decentralized character of the metaverse plays a significant role in deciding the freedom of users. Therefore, the decentralization aspect differentiates the metaverse from the current Internet [36].
