The technology used to create immersive environments for gaming and training is virtual reality (VR) and augmented reality (AR). VR provides a fully immersive digital experience where users can interact with 3D environments via specialized headsets, while AR overlays digital information onto the real world through devices like smartphones or smart glasses. Both technologies enhance user engagement and facilitate realistic simulations for training, education, and entertainment purposes. Their application ranges from gaming experiences to professional training scenarios, improving learning and retention in various fields.
