The Extended Reality Technology and Its Utilization in Metaverse

In today's world, where digital changes and transitions are experienced with the developments in technology, many inventions and innovative applications enter daily life. The extended reality technology, which covers virtual reality, augmented reality, and mixed reality technologies, is among these innovative applications. These technologies not only change the way individuals get information, rejoice, make decisions, and act but also enable the creation of a participatory experience. For this reason, the extended reality technology, which has been increasingly used in many fields and disciplines, is one of the significant building blocks of the widely spoken Metaverse. Based on the convergence of technologies that enable multi-sensory interactions with extended reality technology, digital objects, and people, Metaverse is defined as a network of immersive environments with interconnected social networks on permanent multi-user platforms. Accordingly, in this network, it is possible to travel, work together, play games, shop, and engage in educational activities with avatars and digital twins created and controlled by users. In this study, extended reality technology, which is one of the significant building blocks of Metaverse, and the use of this technology in Metaverse were discussed. In this regard, the study, which has been planned as a descriptive study, includes literature analysis and definitions and explanations about extended reality technology and Metaverse; Afterward, the use of extended reality technology in Metaverse was explained by supporting it with current examples.
