The technology that enhances physical reality by overlaying digital information is called augmented reality (AR). AR integrates computer-generated content with the real world, allowing users to interact with both digital and physical elements simultaneously. Common applications include gaming, navigation, education, and training simulations. By providing contextual information in real-time, AR enriches user experiences and fosters greater engagement. Technologies like smartphones, AR glasses, and heads-up displays facilitate the accessibility and implementation of augmented reality in various settings.
