The primary uses of augmented reality (AR) in training involve enhancing learning experiences through interactive simulations. AR technology overlays digital information onto the real world, providing contextually relevant insights that aid retention and understanding. In fields like healthcare, AR can simulate real-life medical scenarios for hands-on training without risks. Additionally, industries such as manufacturing utilize AR for maintenance and assembly training, where technicians can visualize instructions overlaid on machinery. This immersive approach enhances engagement and skill acquisition.
