The technology used to create immersive environments for gaming is known as virtual reality (VR) and augmented reality (AR). VR technology uses headsets and sensors to provide users with a fully immersive 3D experience, allowing them to interact with virtual worlds. On the other hand, AR overlays digital elements onto the real world, enhancing the gaming experience. Both technologies require advanced hardware and software to render realistic graphics, sounds, and interactions, creating engaging experiences for gamers.
