In recent years, generative AI, such as language and image models, have started to revolutionize virtual reality (VR) by offering new opportunities for immersive and personalized interaction. This paper explores the potential of these Intelligent Augmentation technologies in the context of VR, analyzing how the generation of text and images in real time can enhance the user experience through dynamic and personalized environments and contents. The integration of generative AI in VR scenarios holds promise in multiple fields, including education, professional training, design, and healthcare. However, their implementation involves significant challenges, such as privacy management, data security, and ethical issues related to cognitive manipulation and representation of reality. Through an overview of current applications and future prospects, this paper highlights the crucial role of generative AI in enhancing VR, helping to outline a path for the ethical and sustainable development of these immersive technologies.
