Definition of Metaverse

Metaverse is a combination of two words, Meta and Universe. In general, we can consider the metaverse “beyond the world.” Metaverse is a digital reality that combines aspects of social media, online gaming, Augmented Reality (AR), Virtual Reality (VR), and digital currencies to allow users to interact virtually.

Instead of merely viewing digital content, users in the metaverse will be able to immerse themselves in a space where the digital and physical worlds converge. You can put virtual reality glasses on your eyes using metaverse technology and enter another world. In this new world, you can talk to your friends and walk anywhere you want.

Metaverse Technologies

The metaverse seeks to create a world beyond the physical world in which many real-world activities are possible. Activities such as time travel, traveling to celestial spheres, and talking to avatars are all activities that will be possible in the metaverse. But which technologies provide this possibility. In this section, we will review the leading technologies of the metaverse.

A. Augmented Reality in the Metaverse

Augmented Reality (AR) is an advanced version of the physical world created through visual, audio, and digital sensory stimuli. One of the main features of augmented reality is the placement of objects created in the virtual space next to other real things using special displays. Another feature of augmented reality is that users must be able to interact with virtual 3D objects in this space. In the metaverse, we seek to build a virtual world where virtual objects can coexist with objects located in the real world and provide users with a real sense of being in the world

B. Virtual Reality in the Metaverse

Virtual Reality (VR) is the experience of a simulated environment that can be like the real world or have completely different characteristics. In virtual reality, using the best hardware and advanced graphics, a simulated environment with artistic features is created in which you are not a passive participant and are fully involved in the conditions in the space. In these systems, with a virtual reality headset, you enter a 3D world like the real world and get a new experience of being in the virtual space.

C. Artificial Intelligence in the Metaverse

Artificial Intelligence refers to the sciences that seek to make machines more intelligent by using the natural intelligence model in humans and animals. The users generate huge amounts of diverse data in the metaverse due to their activities. This data can be text, image, audio, or geographical. These data are suitable inputs for artificial intelligence in the metaverse to improve its work system or obtain information from its users.

D. Blockchain Technology in the Metaverse

The first reason for the importance of blockchain in the metaverse is to create a safe platform for people to communicate directly. This is important because private information is no longer available to organizations. On the other hand, regarding decentralization, governments cannot restrict different people, and all people can use it by adhering to the principles of blockchain. In addition, the emergence of Non Fungible Tokens (NFTs) led to the development and faster growth of the metaverse.
