The primary use of augmented reality (AR) in training simulations is to enhance learning experiences by overlaying digital information onto the real world. AR provides immersive, interactive environments that allow trainees to practice skills and scenarios in a safe setting. This technology promotes active learning by engaging users with visual aids and real-time feedback. Applications range from medical training to military simulations, facilitating complex skill acquisition and decision-making processes. Overall, AR in training fosters retention and boosts confidence, helping individuals prepare for real-life situations.
