Virtual Reality (VR), Augmented Reality (AR), and Mixed Reality (MR) are transforming how we perceive and interact with the digital world. VR immerses users in entirely simulated environments, providing a sense of presence in a computer-generated world. AR overlays digital information onto the real world, enhancing our surroundings with interactive data. MR combines elements of both, intertwining digital and physical realities. These technologies find applications across various sectors, from gaming and entertainment to education, healthcare, and industrial training. As advancements continue, the boundary between the virtual and real worlds becomes increasingly blurred, opening new possibilities for communication, collaboration, and innovation.
