Augmented Reality (AR) is a technology that overlays digital content onto the real world through devices like smartphones, tablets, and AR glasses. It enhances user experiences by blending virtual elements with physical environments. AR is widely used in gaming, retail, education, and healthcare for immersive and interactive applications. Frameworks like ARKit for iOS and ARCore for Android simplify AR app development. With advancements in hardware and software, AR continues to redefine how users interact with digital content.
