Augmented reality (AR) plays a significant role in training and simulations by enhancing the learning experience through immersive interactions. AR overlays digital information onto the real world, allowing trainees to visualize complex systems or processes in real-time. This technology is beneficial in fields such as healthcare, manufacturing, and military training, providing realistic scenarios without the associated risks. By facilitating hands-on practice and immediate feedback, AR boosts engagement and retention, making it an effective tool for skill development and knowledge acquisition.
