Introduction

I. INTRODUCTION

The metaverse has been defined as a three-dimensional space representation based on virtual and augmented reality, where people can use personal avatars to work, academic, play and synchronously communicate with each other [1]. Metaverse is a compound word combined with “meta” (beyond) and “verse” (the root of “universe”; the world), which denotes a new virtual universe created beyond the real world [3].

Metaverse, once confined to science fiction, is now a transformative digital reality. It's a vast, interconnected universe where virtual and physical worlds blend seamlessly. In this space, people from across the globe interact, collaborate, and innovate without constraints. Businesses thrive, and creativity knows no bounds. Yet, as we explore this digital frontier, questions about identity and ethics arise. The Metaverse isn't just a conception; it's a testament to our measureless imagination, reconsidering how we live and connect in our ultramodern world. Like a digital supremacy rising from the ashes of cyberspace, the Metaverse represents a new era of human interaction, creativity, and exploration. It can also be used for academic purposes. Academics are increasingly drawn to the Metaverse, and they have begun to conceptualize the phenomenon by presenting frameworks and outlining research agendas. In education metaverse is clearly defined, and a detailed framework of the metaverse in education is proposed, along with in-depth discussions of its features. This research paper aims to review several representative articles to give a clear view of the metaverse in education, including its definition, framework, typical features, implicit operations, challenges and future exploration issues. The main benefactions of this paper include the following points:

1. The origin, definition and features of the metaverse are discussed.
2. A detailed framework of the metaverse, along with the discussion about features of metaverse-based literacy compared with in-person classroom literacy and screen- based remote learning.
3. Implicit operations, challenges, and future exploration motifs of the metaverse in education are presented [3].

Companies in this industry are eager to explore ways to turn to account on the metaverse to create virtual experiences for their consumers. Consumers are gradually opting for metaverse products and services and participating in virtual worlds. Tech giants such as Nvidia, Decentral, Roblox and, The Sandbox, strive to create metaverse platforms as virtual worlds in which people interact, play games, work and do business.

Enterprises are experimenting with metaverse operations in the plant that make on the virtual operations companies stationed during the pandemic to support remote work. An early application of metaverse technologies involves workplace training. Some hospitals are formerly using VR and AR to train for common medical procedures, reported TechTarget news write Esther Ajao. One technology lately approved by the FDA is Medivis, an AR surgical system that lets surgeons quickly sync with a hospital's digital imaging system. Non-fungible commemoratives (NFTs) figure to play a big part in the usefulness and popularity of the metaverse. NFTs are a secure type of digital asset grounded on the same blockchain technology used by cryptocurrency. Rather of currency, an NFT can represent a piece of art or digital real estate. An NFT gives the proprietor a kind of digital deed or evidence of ownership that can be bought or sold in the metaverse [2].

The forthcoming sections of this research paper will concentrate on explaining the conceptual idea behind metaverses and also help understand it's Real-World applications and Impact. The outcomes of this research will help us to understand metaverse from a consumer’s viewpoint and clarify the comprehensions of the metaverse.

II. PREVIOUS WORK

The description of the Metaverse varies, depending on point of view and purpose. still, the generally bandied metaverse is a virtual world that's like the real world it's a space for interacting with other druggies. The metaverse began with Snow Crash in 1992, and it was generally studied as the Second Life terrain in 2006 [4].

In former literature, Kang (2021) proposed a metaverse frame with implicit core heaps, including tackle, cipher, networking, virtual platforms, cloverleaf tools and norms, payments service, content, service, and means, as well as introduced its reasons in detail. still, there are no farther explanations for the perpetration of the metaverse in detail. Park and Kim (2022) divided the metaverse into three essential factors (i.e., tackle, software, and contents) and three approaches (i.e., stoner commerce, perpetration, and operation) for the metaverse in a general meaning [5,6].

Other scarce proposed work on the metaverse in education from Hwang and Chien (2022). They bandied the places (i.e., intelligent teachers, intelligent tutees, and intelligent peers) in furnishing educational services and implicit operations of metaverse for educational settings from the perspective of AI [7].

Other 3D interactive platforms similar as Roblox and Fortnite have also be described as precursors to the metaverse, where the functionality allows druggies to produce incorporations and interact with other gamers within their own virtual macrocosm (Damar, 2021) [8].

III. METAVERSE: THE VIRTUAL UNIVERSE

A. Origin

Metaverse is a compound word combined with “meta” (beyond) and “verse” (the root of “universe”; the world), which denotes a new virtual universe created beyond the real world [3]. The term “metaverse” was first coined in the 1992 cyberpunk science fiction novel Snow Crash written by American novelist Neal Stephenson (Stephenson, 1992; Joshua, 2017). In this novel, humans could freely pierce a 3D space that reflects the real world through digital agents and interact with each other. Over the next three decades, the metaverse concept was more vividly depicted in science fiction movies, such as Ready Player One, Lucy, and The Matrix [9]. At that time, the metaverse envisioned by films, couldn't come into being in reality. In this decade, the rapid progress of arising technologies, similar as wearable devices and three-dimensional (3D) photography, has helped people to get access to the virtual world. In March 2021, the sandbox game Roblox was listed in New York under the halo of “the first stock of the metaverse”; in October, Facebook placarded it rebrand its name to “Meta.” From that time, extensive efforts have gradually been carried out by many countries across the world to make it a reality. This sleeping “captain” was truly awakened.

B. Definition

The Metaverse is an immersive network of socially connected environments in a persistent multi-user platform. This Metaverse serves as a mecca for education, work, and entertainment. The Metaverse has been depicted in books, pictures, and video games as not just supplementing but significantly replacing real-life experiences [22]. The Metaverse was discussed in, which was inspired by Stephenson’s Snow Crash novel (1992) and is a virtual world parallel to the real world where avatars interact [10].

Metaverse was introduced in as a new form of Internet application and social platform. According to, the Metaverse consists of both real and virtual worlds, in which people are able to interact with each other through assistive objects such as immersion avatars, devices, and platforms. In addition, there are various virtual, hypothetical, and fictional ideas that differ in dimension from it but are similar in concept, such as the mirror world, the universe, the multiverse, the omniverse, and the mega verse.

C. The Seven-Layer Architecture

Entrepreneur and author, Jon Radoff, has suggested that the Metaverse comprises seven distinct layers, with each layer influencing one aspect of the user experience [11]:

1. Experience: Physicality’s limitations will be removed as physical space is evaporated in the digital world. The Metaverse will provide people with a wide range of experiences we can’t presently enjoy.
2. Discovery: Through app shops, search engines, and standing websites, customers can learn about new platforms thanks to this subcaste. Revealing new technology and communities requires this pivotal step.
3. Creator Economy: To produce digital assets or experiences, developers use different design tools and applications. Numerous platforms are developing more straightforward creative methods, as an example, drag-and-drop tools.
4. Spatial Computing: It blends virtual reality (VR), mixed reality (MR) and augmented reality (AR). Over time, it has developed into a significant technology category that enables users to interact with 3D surroundings for enhanced experiences.
5. Decentralization: There won’t be any authority that rule over the Metaverse. Scalable ecosystems will support business possessors in furnishing a more comprehensive range of specialized digital particulars as the Metaverse expands, enabled by blockchain technology.
6. Human Interfacing: The hardware subcaste of the Metaverse must include human interfacing. Any VR can accept a person’s body as a three-dimensional, realistic avatar.
7. Infrastructure: The technology that provide power to people’s widgets, connects them to the network, and distributes content is part of the infrastructure layer. In future, 5G networks will enhance the capacity of the Metaverse.

IV. IMMERSIVE REALITIES: EXPLORING VR, AR, MR, AND XR

The access point for the metaverse requires multisensory relations with several technologies: virtual environments, digital objects and people immersive technologies, augmented reality (AR), virtual reality (VR), mixed reality (MR) and extended reality (XR) [12]. These technologies support the creation and development of the metaverse and facilitate it’s immersive experiences in the digital world. VR technology provides users with a connected experience in the metaverse. On the other hand, AR expands the use of virtual reality by overlaying digital information onto the physical environment. XR is an extended reality, a term used to include VR, AR, and MR. Extended reality is used for virtual commerce or v-commerce to produce computer-mediated indirect experiences [13].

A. Virtual Reality (VR)

Virtual reality (VR), the use of computer modelling and simulation that enables a person to interact with an artificial three-dimensional (3-D) visual or another sensory environment. VR operations immerse the user in a computer-generated terrain that simulates reality through the use of interactive devices, which send and receive information and are worn as headsets, gloves, goggles, or body suits. In a typical VR format, a user wearing a helmet with a stereoscopic screen view animated images of a simulated terrian. The vision of telepresence is affected by motion sensors that pick up the user’s movements and adjust the view on the screen accordingly, usually in real time (the instant the user’s movement takes place). Therefore, a user can travel a simulated suite of rooms, experiencing changing viewpoints and perspectives that are convincingly related to his own head turnings and ways. Wearing data gloves equipped with force-feedback bias that provide the feeling of touch, the user can even pick up and manipulate objects that he sees in the virtual environment [18].

???????B. Augmented Reality (AR)

AR adopts a different approach towards physical spaces; it embeds digital inputs, virtual elements into the physical environment so as to enhance it [14]. It spatially merges the physical world with the virtual world. The end outcome is a spatially projected layer of digital artifacts mediated by devices, e.g., smart phones, tablets, glasses, contact lenses or other transparent surfaces [15]. And, AR can also be implemented in VR headsets with pass-through mode capability by displaying input from camera sensors. The most popular usage of Augmented Reality in recent times is the advent of Poke´mon Go, an AR game produced by Niantic [16].

It allowed users to travel around their city to capture virtual creatures known as Poke´mon, which spawn virtually in their physical environment [17].

???????C. Mixed Reality (MR)

MR is a more complex concept and its definition has fluctuated across time, reflecting the contemporary technological trends and dominant linguistic meanings and narratives. MR is sometimes represented as an advanced AR iteration in the sense that the physical environment interacts in real time with the projected digital data [19]. For instance, a scripted non-player character in an MR game would recognize the physical environments and hide behind under a couch or behind a desk. Similar to VR, MR requires special glasses. However, for the purpose of this article, we accept the conception of MR as any combination of AR and VR as well as intermediate variations such as augmented virtuality [20]. The rationale behind this decision is the long-term technological evolution and maturation of Augmented reality to include interactive affordances. Therefore, AR and VR remain the two fundamental technologies and MR their combination [15].

???????D. Extended Reality or Cross Reality (XR)

Extended Reality (XR) is a catch-all term for any immersive technologies that expand our perception of reality by combining the virtual and “real” worlds or by producing a fully immersive experience. Virtual reality and Augmented reality can be considered as subcategories of XR, or as technologies that exist on the XR technology spectrum. The word XR is frequently used to refer to the full group of VR and AR technology [21].AR smart glasses, hologram displays, haptic, and VR headsets that are Metaverse-based can improve the user experience in extended reality. Devices of this type facilitate a wide range of physical services in the virtual world and aid users in navigating the Metaverse smoothly. While XR performance continues to improve, there are still some challenges to overcome; for example, the camera on a mobile phone can only be used for one app at a time, which prevents the integration of multiple applications into a hybrid physical–digital environment [22].

In short, Virtual Reality (VR) technology allows us to see the real world from a different perspective than what we see through computer tools. The use of this technology is widespread across many industries, including military, entertainment, medicine, manufacturing, training, and many more, creating an immersion mode for users in a computer produced virtual environment. To probe, explore, and investigate virtual reality, experimenters concentrated on the human sight sense. At present, attention is being paid to the senses of touch, hearing, and sight. Research is also being conducted on the taste and smell senses, such as in the Virtual Cocoon [23].

Augmented reality (AR) uses digital information in physical reality to allow users to interact with digital objects and shells in their terrain. A key difference between augmented reality and virtual reality is that augmented reality doesn't produce a virtual environment but rather simulates the real world. The Metaverse world can be entered using AR (augmented reality). Artificial intelligence and augmented reality are incorporated into the Metaverse for process data, image bracket, recognize faces, and recognize speech. Although AR can be developed for all five senses, most systems are grounded on visual input. There are three types of AR-based systems based on the registration method used: marker less, marker-based, and non-visual. Head-mounted displays are used with these systems [24]. Using augmented reality, computer-generated images, sounds, 3D models, videos, graphics, animated sequences, games, and GPS information can be added to real-world environments [25].

As part of the Metaverse, mixed reality (MR) combines the physical and digital worlds to grease interactivity between humans, computers, and the terrain in 3D. This new technology has been launched with the help of advances in machine vision, cloud computing, graphical processing, and so on. Beyond this, MR is also used for eye tracking, spatial mapping, hand tracking, speech input and spatial audio. The ability to immerse users in a controlled, real, and interactive environment has led to research on medicine, engineering, and education [26].

Extended reality is a technology that includes several new ongoing and developing technologies offering an immersive digital experience. Augmented reality (AR), Virtual reality (VR) and mixed reality (MR) are the three sides of extended reality. In Virtual reality, the user enters the processed world through a headset. Augmented reality (AR) allows users to see digital objects in real space, while MR allows them to interact with objects in virtual space. AR smart glasses, hologram displays, haptic, and VR headsets that are Metaverse-grounded can ameliorate the user experience in extended reality. Devices of this type grease a wide range of physical services in the virtual world and aid users in navigating the Metaverse easily. XR is still being improved and bettered as a result of many advances in hardware and the increase in network effectiveness that 5G brings. While XR performance continues to improve, there are still some challenges to overcome; for example, the camera on a mobile phone can only be used for one operation at a time, which prevents the integration of multiple applications into a hybrid physical–digital environment [27].

V. METAVERSE FEATURES

The working of the Metaverse is based on some key features such as Blockchain-based operations, Intersection with artificial intelligence (AI), The use of virtual land, decentralized network, quantum mechanics, Incorporation of avatars, etc.

A. ??????Bockchain-based Operations

Blockchain is widely believed as one of the fundamental infrastructures of metaverse, because it can bridge isolated small sectors together and provide a stable economic system, which helps offer transparent, open, efficient, and reliable rules for metaverse. Data transmission and verification mechanism provide network support for various data transmission and verification of metaverse economic system.  Consensus mechanisms solve the credit problem of metaverse transactions.  Distributed storage of blockchain ensures the security of virtual assets and the identities of metaverse users.  Smart contract technology offers a trustworthy environment for all participating entities in the metaverse. Once deployed, the code of smart contracts cannot be changed anymore. All clauses depicted in those contracts must be completely executed [28]. Without the support of blockchain technology, it will be difficult to identify the value of the resources and goods trading in the metaverse, especially when those virtual elements have economic interactions with the real-world economy. Thus, it is undoubtedly worth exploring the blockchain technology in the metaverse. In this section, we introduce the blockchain empowered applications in metaverse considering four perspectives, i.e., Cryptocurrency, Transaction characteristics, Authentication, and Market & Business.

It is a well-known fact that there are many Blockchain platforms out there that use cryptocurrencies and NFTs for their various services like creating or owning a digital asset or even monetizing them. Now, without such a feature of Blockchain, Metaverse remains incomplete as it would warrant decentralization and get entangled in various centralized data storages. Encyclopedically Blockchain can serve singly being a digital source operating on the principle of decentralization and this distinguishes Metaverse from the traditional internet [29].

1. Cryptocurrency for Metaverse

Cryptocurrency is one of the main applications under the spotlight empowered by blockchain. It also makes blockchain more popular. The trust of a wide range of users supports the value system of cryptocurrencies and drives both the rotation and trading of cryptocurrencies. To date, more than 12,000 virtual currencies have been issued worldwide, and new virtual currencies are still being created every single day. The price of mainstream cryptocurrencies keeps hitting record highs. [30]

Like the real world builds upon fiat currencies, the future metaverse inevitably needs cryptocurrencies, which deliver value during their circulation, payment, and currency of settlement. In detail, blockchain systems have enforced a series of operations for cryptocurrencies, such as creation, recording, and trading. All these fundamental operations are necessary for the metaverse.

2. Transaction Characteristics in Metaverse

Metaverse is anticipated to have various types of financial issues such as estate purchases, item settlements and service accessions which include nearly everything people do in the physical world. Thus, transactions in metaverse are not simply related to intra-metaverse scenario, and not only for token transferring.

Once a user launches a transaction on the conventional blockchain, the transaction will be first broadcast and be stored in their local transaction pools. The miner picks up a certain number of transactions and next performs the hash-grounded agreement. The block generated by the first miner to find an output to the mystification that fits the specified difficulty will be uploaded to the chain and broadcast to all the other miners. The existing blockchain agreement protocols have several constraints that help them from being directly applied to metaverse. For instance, the PoW medium relies on miner’s hash power to achieve consensus on a certain transaction data [30]. Considering the huge data volume of metaverse, PoW consensus will consume a large amount of mining resources. Since the Matthew effect is more pronounced on metaverse, the PoS mechanism cannot ensure the fairness of the miners participating in the consensus in metaverse. Therefore, metaverse needs new consensus protocols and new blockchain mechanisms to meet the rigorous requirements of transactions.

3. Blockchain-Empowered Market in Metaverse

Blockchains before Ethereum, such as Bitcoin, only support token transferring. Until the emergence of the Ethereum platform, smart contracts begin to support Turing-complete programming. Complicated businesses could be executed in a virtual machine through smart contract codes. Ethereum understands the upgrade of blockchain applications from cryptocurrency to crypto business. Several blockchain reconfiguration of market and business could be implemented. Empowering by the advanced blockchain technologies, decentralized finance can boost the decentralized market and business in the metaverse. We review several representative studies related to the DeFi market and business here [30]. In, the authors analyse the behaviour of arbitrage bots in the context of the cryptocurrency market. They find that robots could observe the transactions in the transaction pool and perform arbitrage without complexity. They also present a cooperative strategy to maximize the profit of arbitrage robots and point out that miners could act as arbitrage robots under certain circumstances.

The software that implements the blockchain is open-sourced so that anyone can make upon it and scale their financial requirements.

4. Blockchain-Empowered Authentication in Metaverse

Recently, the economic activities in metaverse mainly include the auction of virtual assets, including land, scarce items, precious real estate, the development and leasing of land, the rewards of game tasks, and the profits come from investing in cryptocurrency.

Non-Fungible Tokens (NFT) has been mainly used to commemorate special moments or to collect digital assets, and recently it is creating a new digital content business by combining it with metaverse. Non-Fungible Tokens (NFT) can guarantee the uniqueness of the digital assets by keeping encrypted transaction history permanently on the blockchain. Each token has a unique recognizable value, which enables to authenticate the ownership of digital assets. For example, the blockchain-empowered Non-Fungible Tokens has been applied to prove the uniqueness of the avatar and the created things in metaverse [31].

???????B. Intersection with artificial Intelligence (AI)

Artificial Intelligence is a research discipline progressed based on the hypothesis that every aspect of literacy can in principle be so precisely described. The state-of-the-art AI studies focus on deep learning, machine learning, and reinforcement learning in the fields including computer vision, decision-making, and natural language process (NLP). Intuitively, the improvements of artificial intelligence in the real world motivate people to realize metaverse. For illustration, machine learning provides technical support for all systems in metaverse to reach or exceed the position of human’s learning. It shall significantly affect the operational effectiveness and the intelligence of metaverse. Intelligent voice services give technical support, such as communication and voice recognition, for metaverse users [32].

1. Avatars: One of the most interesting and spoken about concepts of the Metaverse is Avatars. People are creative and love the thought of designing themselves in a virtual world. They can change their hair colour, style of clothing to their preference.  AI has the ability to analyse 2D user images or 3D scans to create very realistic and accurate Avatars. Companies similar as Ready Player Me have formerly laboriously been using AI to help generate Avatars for the Metaverse [30].
2. Digital Humans: Digital humans have the ability to see and listen to users to understand what they are saying. They can also use speech and body language to create human-like conversations and interactions. In the Metaverse, digital humans are three dimensional chatbots that can respond and react to your actions in a VR world. They are non-playing characters (NPC), which is a character in the virtual reality or game whose responses and actions are determined by an automated script or set of regulations, in comparison to a character controlled by a player. Digital humans are purely built using AI technology and are an important element to the construct of the Metaverse [33]. Digital humans can range from NPC’s (Non-Fungible Tokens) to automated sidekicks in the VR plant. 
3. Language Processing:  Users from all over the world will be suitable to profit from interacting in the Metaverse. With the use of AI, you will be suitable to interact in the Metaverse freely.AI can break down natural languages such as English, transforming them into a machine-readable format. An analysis is also performed, an result (or response) is produced which is also converted back into English and transferred over to the user [33]. Depending on the AI’s training, we would hope to think that most languages have been read in, making it useable for everyone [30].
4. Learning the Data: We know that one of the major elements of Machine Learning and Artificial is learning data. When a model is fed historical data, it learns the previous model’s outputs, and based on these, it can suggest new outputs. The more data and human feedback that gets ingested into the model, the outputs get better and better every time. This is building the hope that AI will eventually be able to perform tasks and provide the correct outputs the same way as human beings. The human intervention will decrease, this way the scalability of the Metaverse will continuously evolve [33].

???????C. The use of Virtual Land (Parcels)

The value for virtual land on the Metaverse is soaring. On the Metaverse, land can be bought by anybody for cryptocurrencies. The land is under NFT, a blockchain asset class that one cannot trade for other effects or things. Size refers to the fundamental numerical no. of pixels in a part of Metaverse real estate.[11]

Virtual gaming, Digital storefronts, or even entertainment can be interacted with on virtual land. Its size and position will determine the uses for the land. For instance, plots near a VR road may be worthwhile because of the potential for display announcements.

???????D. Decentralized Network

The choice between decentralization and centralization is a significant factor, impacting not only the platform itself but also carrying broader counteraccusations for humankind such as how we use technology, how we socialise, global culture, our way of life, and overall freedoms [34].

1. User Empowerment: Decentralization supports users to have more control over their virtual experiences. In a decentralized metaverse, approaches have ownership and control over their assets, data, and identities. They can freely interact with others, customize content produce and retain the value they induce within the metaverse.
2. Privacy and Security: Decentralization enhances sequestration and security for metaverse users. With decentralized systems, user data is not concentrated in a single central authority, reducing the risk of large-scale data breaches or unauthorized access. Users can choose how their personal information is participated, minimizing the exposure of sensitive data.
3. Censorship Resistance: In a decentralized metaverse, there is lower vulnerability to suppression or arbitrary control. Traditional centralized platforms can impose restrictions on content, limit user expression, or widely apply programs. In a decentralized metaverse, the decision-making processes and governance are distributed, ensuring more participations without politicization.
4. Interoperability and Open Norms: Decentralization fosters interoperability and the use of open norms. It allows different virtual worlds, platforms, and operations to connect and interact seamlessly. Users can move their means and individualities across different parts of the metaverse, promoting a further interconnected and diverse ecosystem [34].
5. Economic Openings: Decentralization enables new economic models and openings within the metaverse. Users can earn and trade digital assets, share in virtual economies, and monetize their skills and creations. Decentralized finance (DeFi) principles can be applied, allowing for peer-to-peer transactions and removing interposers, fostering a more equitable and accessible economic landscape.
6. Community Governance: Decentralized metaverses empower users to attend in the decision-making processes that shape the metaverse's rules, programs, and development. Through decentralized governance mechanisms, users can have a voice in determining the direction and elaboration of the metaverse, ensuring that it aligns with their collective interests and values [34].

Overall, decentralization in the metaverse promotes user autonomy, sequestration, security, and participation. It creates a more inclusive, diverse, and user-centric virtual terrain where individuals can freely express themselves, unite, and explore new possibilities.  Although complete decentralization of metaverse infrastructure may not be feasible for all rudiments, it is crucial to maximize its application wherever possible [34]

.???????E. Metaverse with Quantum Mechanics and Their Applications

Some fields like quantum machine learning have proven increasingly popular in various industries like finance and the pharmaceutical industry. Placing this in mind, quantum computing has a definite part in bringing the metaverse to life, helping to execute several critical operations.

Quantum computing will find itself in the metaverse through security operations. Security has long been a question mark of QM for technology experts. Still, in the metaverse, as further relations are being captured, quantum-resistant security will be demanded for any commerce and transactions that take place, with quantum-resistant blockchain technology being a go to technology.

A more effective way that quantum computing can play an essential part in the metaverse is through computation. One of the better use cases for quantum computing is ensuring the increased effectiveness of operations. Experimenters have been developing applications based on optimization tasks. The metaverse uses lots of simulation and computation, so quantum computing can be leveraged to enhance computation and the overall experience. The wide range of quantum algorithms that researchers are exercising can be applied in an alternative metaverse.

Metaverses will also need some amount of randomness to ensure inhabitants and algorithms don’t manipulate the system. Using quantum randomness, developers can ensure that the rules used to keep the metaverse safe aren’t being used in unscrupulous ways. Instead, a false random number, a qubit series can be utilized to form random bits, with some companies specializing in quantum random number generation. And also, there’s machine learning. As the complexity of the metaverse builds, machine literacy will play a decreasingly important part in how it evolves. The need for increased machine learning in the metaverse will be just as profound as in reality. With more development of quantum machine learning, more operations will take place in the metaverse. Meanwhile, quantum key distribution is a smart tool that provides secure interactions within the metaverse [35]. The metaverse is a conception we will gradationally get used to, and quantum computing is one way of ensuring everyone understands the operations and capabilities of the metaverse, plus enjoy the potential benefits the metaverse offers.

VI.  META-EDUCATION

As indicated by scholars, education is one of the most significant operations of the metaverse with immersive potential in the coming future. The presence of the metaverse can be served as a new educational environment [36]; thus, the metaverse in education can be regarded as an educational environment enhanced by metaverse-related technologies which fuse with the elements of the virtual and the real educational environment. It enables learners to use Wearable gadgets to enter the educational setting without being limited by locations and time and allows them to use digital identities to have real-time interactions with different forms of items (intelligent NPCs, avatars or virtual learning resources). As an outcome, they can feel present as if they are in a real-world educational setting. From this standpoint, it can be seen that applying the metaverse in education can unlock a variety of fantastic learning experiences for learners [9].

Pertaining to Metaverse’s potential for educational radical innovation, procedural skills development (e.g., surgery), laboratory simulations, and STEM education are among the first application areas with spectacular outcomes in terms of training speed, performance and retention with Augmented reality and Virtual Reality-supported instruction [37,38]. Thanks to the ability to capture 360-degree panoramic images and volumetric spherical video, the Metaverse can enable immersive journalism to accurately and objectively educate mass audiences on unfamiliar circumstances and events in remote locations [39]. Also, new models of Metaverse-powered distance education can arise to break the limitations of 2D platforms. Meta-education can allow rich, hybrid formal and informal active learning experiences in alternative, perpetual, online 3D virtual campuses where students are co-owners of the virtual spaces and co-creators of liquid, personalized curricula [12].

VII. POSITIVE OUTCOMES OF METAVERSE

A. Conferences and Meetings

The pandemic of COVID-19 isolation across the world forced companies to explore the virtual realm of collaboration. Colleges, schools, organizations, and other institutions resorted to working remotely to continue their scheduled work or regular tasks. While existing online conferencing platforms only allow video and audio collaboration, the metaverse can open paths to exclusive interaction. Microsoft Corporation kick-started its journey to metaverse with a new feature (Mesh) [40] for Microsoft Teams, which allows users to construct their virtual avatars, and participate in conferences online [41]. Metaverse offers an effective solution to institutions seeking to organize engaging and interactive conferences or meetings remotely with clients and colleagues. This innovation can also change the entire landscape of virtual collaboration and communication [17].

???????B. Experienced Virtual Tours

Over the years, computer graphics have advanced significantly and at such a rapid pace of today, it enables the simulation of objects and characters through 3D graph technology in the virtual environment. These Digitally simulated objects have appealing features that make them look so close to reality.

Using this sophisticated technology, people in the metaverse can experience a Google Earth-like-virtual world, allowing them to travel to essentially any location in the world, including the Disney Land, Taj Mahal, Venice, London, Paris, and much more. People can virtually tour any location and witness its beauty and magnificence without even leaving their homes [17].

???????C. VR in Education

Bailenson [41] suggests the integration of immersive, headset-based Virtual reality (VR) into education for four primary purposes in location-based education.

1st, for rehearsing and practicing dangerous activities such as conducting a surgical operation or piloting an airplane where the stakes of failure are very high with grave consequences.

2nd, to reenact a counterproductive or inconvenient situation such as managing a problematic behaviour in a school / college or handling a demanding business client.

3rd, to perform something impossible such as travel virtually back in time to archeologically site reconstructions or to internal human body organs observation.

4th, immersive Virtual reality (VR) is also recommended for expensive or rare experiences such as an underwater wreckage or a group field trip to a tropical forest.

All these use cases can be classified as single-user experiences.

???????D. Advanced Training

With the help of Virtual Reality (VR), neurologists and surgical trainees can visualize the human brain in a virtual environment or terrain and help better understand the essential concepts and critical parts involved in neurology. Numerous technological breakthroughs in different fields of training showcasing how VR have been integrated to assist in advanced training [42].

Metaverses have the potential to completely revolutionize how professionals in the fields of engineering, medicine, emergency services, warfare, military, and many more, get skilled trainings.

???????E. Virtual Commerce and Digital Assets

The metaverse provides e-commerce enterprises with a new avenue to explore and serve consumers with a distinctive purchasing experience. Several businesses have already started to develop the AR games, allowing customers to sample things visually before buying. For example, Customers can try on their wearing using AR (Augmented reality) on Shopify [43] before purchasing.

Additionally, users can bring any form of digital assets that can be represented digitally, including music, artwork, photos, videos, and much more, into the metaverse. With the assistance of cryptocurrencies, these digital assets may be traded with one another, and thanks to blockchain technology each transaction can be correctly validated. The cryptocurrency obtained through trading can be transferred to cash anytime when required.

VIII. CHALLENGES ASSOCIATED WITH THE METAVERSE

In the digital breadth of the metaverse, where virtual reality melds with the tangible, several challenges impend on the horizon, shaping the future of this connected realm.

???????A. The Tapestry of Interoperability

Weaving a seamless shade of connected virtual worlds and platforms demands the delicate thread of interoperability. Uniting disparate technologies and ecosystems into a harmonious whole requires innovative results and universal norms.

???????B. Spanning the Heights

Spanning the towering peaks of user demand while maintaining the integrity of the user experience is a daunting rise. As millions cross the metaverse contemporaneously, the challenge lies in constructing an infrastructure sturdy enough to bear this colossal digital cargo without sacrificing speed or quality.

???????C. VR in Education

Within this immersive digital realm, the sentinel of privacy and security must stand guard. Securing user’s data from cyber threats and ensuring a sanctuary against virtual trespassers presents a formidable challenge, demanding constant alert and innovative fortifications.

???????D. Content Moderateness

As in any online space, the metaverse will need mechanisms to moderate content, prevent harassment, hate speech, and other forms of harmful behaviour. Developing effective and fair content temperance programs is a challenge, especially given the diverse cultural morals and legal regulations around the world.

???????E. Monetizing the Infinite

In a world without physical boundaries, the problem of monetization echoes through the infinite corridors of the metaverse. Striking a balance between profitability and user experience requires innovative models—maybe a blend of subscription, microtransactions, and virtual experiences that tantalize the senses.

???????F. Framing the Virtual Reality

The metaverse hungers for developers, for engineers of virtual reality. The challenge lies not only in designing visually stunning 3D landscapes but in crafting experiences that reverberate with the human soul, experiences that are not just observed but lived.

???????G. Ethical Enterprises

The metaverse raises ethical questions regarding identity, connections, and even the nature of reality. As people spend time in virtual spaces, problems about the impact on their real-world relationships, mental health, and the blurring of virtual and physical realities become increasingly important.

???????H. Intellectual Property

Virtual worlds involve the creation of intellectual property, including surroundings, virtual goods, and experiences. Guarding intellectual property rights while allowing for creativity and innovation is a complex challenge.

As the metaverse continues to develop, it's likely that new challenges will emerge, and solutions will be found to existing ones.

IX. BUSINESS ASPECTS OF METAVERSE AND USE CASES

"business aspects of metaverse" refers to the economic and commercial opportunities arising from the development and expansion of the metaverse, a virtual reality space where users can interact, socialize, and conduct various activities in a computer-generated environment. Digital spaces enable users to interact with the products offered by businesses more efficiently, including a 3D (three-dimensional) view. It’s the 1st step towards a new online marketplace introduction, virtual storefronts will significantly improve user experience. Now, new currencies may be introduced and measured easily, thus boosting business growth, which is proved by the fact that blockchain technology lies at the core of the metaverse platforms. NFT (Non-fungible tokens), cybersecurity, blockchain games, and decentralized finance will be developed in parallel with the metaverse platforms.   

Practical operations and digital products improve communication and interaction in the metaverse through AR and VR implementation [44]. Employees will obtain communicative tools of the new generation where videoconferences are combined with physical (in-person) meetings in digital rooms, providing users with the effect of presence and making the conversation more authentic. With metaverse platforms, businesses can introduce operations for the healthcare industry, in which diseases are diagnosed accurately and quickly (Doctors and other healthcare specialists will have a chance to interact with patients remotely, using the VR of the metaverse) [45].

Businesses involved in esports may come up with immersive applications that provide training via Virtual Reality. Companies operating in the metaverse will generate employment. For instance, new job opportunitys may be related to architecture or the creation of new objects that don’t exist in the real world. With the assistance of NFT certificates, objects will be assigned to specific owners. New job opportunities in the metaverse also imply video games, where trainers, commentators, or even gardeners like in Minecraft are required [45].

According to, Reuters, Boeing, known as an active user of digital technologies, including AR and VR solutions, plans to use the metaverse to design aeroplanes [46]. The plan is to create a digital ecosystem that would comprise services operations, production and product design. Boeing’s mechanics all across the world will use HoloLens headsets for daily work and interaction, and the robots will be involved in the three-dimensional design creation. Also, enterprises can get benefit from the metaverse, unlocking new marketing opportunities. For an example, Anzu, an Israel-based in-game ad platform, has already introduced effective solutions for different gaming platforms, including Roblox. Ads imitate real life and are embedded in the plot of the game. This whole thing is a bit creative since branded clothing and even billboards with advertising appear in the games. Global companies reach Roblox’s audience through this ad solution [45].

X. FUTURE SCOPE

The metaverse has the potential to revolutionize various facets of human existence, and marketing is no exception. Addressing the future of the metaverse requires exploring advancing technologies. Immersive AR and VR applications enable substantial opportunities for interacting with customers in the metaverse [46]. For example, marketers may engage in virtual service encounters with customers either through avatars or agents (AI controlled virtual representations). Metaverse operations will open new avenues for branding, advertising, and product development. Entirely new business models will develop in the metaverse in counselling, consulting, and other personal services. Selling products in the metaverse (NFTs) will produce income opportunities for firms, and firms may build parallel economies where sales accompany, metaverse branding and complement physical product sales [48]. Besides AR and VR, other emerging technologies will play a substantial role in the cultural penetration of the concept.

???????A. Enhanced Tracking and Monitoring

The immersive nature of the metaverse, facilitated by either VR or AR operations, will not only amplify tracking and monitoring opportunities, but also elevate them to a new level in terms of what data firms can collect. For example, VR and AR applications will support firms to track attention in both augmented worlds (through integrated eye-tracking devices in AR glasses) or directly through the gaze of user’s avatars in virtual worlds.

Furthermore, users response to interactions with other users and objects can be tracked, and hardware used to access the metaverse may measure physical consumer response (i.e., galvanic skin response, pupil dilation, etc.).

???????B. The Next Iteration of Concept testing

Concept testing is a crucial step in the new product development process. The metaverse will allow for a more specific, detailed, and accurate understanding of potential consumer demand than simple concept appeal [47]. Firms can better understand the drivers of consumer demand by deploying multiple competing designs in a metaverse environment allowing for quicker and more accurate development of products. As demand changes over time, a metaverse environment will support companies to employ highly competitive approaches to easily detect changes in consumer preference. As changes detected in customer preference, firms can upgrade products with increased speed which might be particularly fast if the product itself is virtual.

???????C. Market Research in the Metaverse

We believe that opportunities for market research in the metaverse will arise for both quantitative and qualitative approaches. As an example, firms can conduct focus groups in a fully virtual setting or in AR-based environments where participants can interact with each other and virtual objects embedded in the physical world. Furthermore, we expect that online ethnography (i.e., ethnography) will further evolve toward a metaverse ethnography in which researchers observe and interact with consumers through AR and VR applications [48]. We also expect that the metaverse will enhance opportunities for quantitative market research similar as running experiments and A/B testing. The metaverse will allow consumers to experience 3D, manipulable product representations in a context in which they can comfortably reframe the market research experience.

???????D. Ethical Considerations

As the metaverse creates new avenues for user insight, the potential for unethical and undesirable use of metaverse data have become increasingly salient, and privacy issues are an omnipresent concern in technology research [48]. We expect that the metaverse environment will magnify both the level of detail that third parties can discern and the time consumers spend from the generated data. Threats to user privacy may arise in different forms, similar as governments using metaverse information to control citizens, corporations sharing or selling consumer information to third-party suppliers, and hackers utilizing metaverse data for Prohibited purposes.
