Technologies used to create immersive virtual experiences include virtual reality (VR) and augmented reality (AR)headsets, like the Oculus Rift or HTC Vive, which transport users to entirely computer-generated environments. AR blends digital information with the real world, utilizing devices like smartphones or smart glasses, exemplified by applications like Pokémon GO. Key technologies underlying these experiences include computer graphics, 3D modeling, and motion tracking. Additionally, interactive design and user interfaces are crucial for seamless user interactions within these digital realms.
