The primary use of augmented reality (AR) in technology is to enhance the real-world environment by overlaying digital information onto physical objects. This technology combines interactive elements like 3D models, graphics, and sounds with the user's real-time view, providing immersive experiences. Applications of AR include gaming, education, marketing, and retail, where businesses engage customers by offering interactive product experiences. By bridging the gap between the digital and physical worlds, AR creates opportunities for enhanced learning, improved shopping experiences, and innovative storytelling.
