Augmented reality (AR) is a technology that overlays digital information, such as images or sounds, onto the real world. This is typically achieved through devices like smartphones, tablets, or AR glasses, which use cameras and sensors to detect the environment and display virtual elements in real-time. AR enhances the user's experience by blending the physical and digital worlds. For example, in gaming, Pokémon GO allows players to see and interact with Pokémon in their actual surroundings. In education, AR can provide interactive lessons, making learning more engaging and immersive.
