Augmented Reality Apps (AR apps) enhance the real world by overlaying digital information onto it. They use a device's camera and sensors to recognize the environment and display graphics, sounds, or other data in real-time. This technology allows users to interact with both physical and virtual elements simultaneously, creating an immersive experience. Common uses of AR apps include gaming, education, and retail. For example, in gaming, Pokémon GO lets players find and catch virtual creatures in real-world locations. In retail, AR apps can help customers visualize how furniture or clothing would look in their own space before making a purchase.
