Augmented Reality (AR) is a technology that overlays digital information, such as images and sounds, onto the real world. This creates an interactive experience where users can see and interact with both physical and virtual elements simultaneously. AR is commonly used in applications like mobile games, education, and training. One of the most popular examples of AR is the mobile game Pokémon GO, which allows players to catch virtual creatures in real-world locations. By using a smartphone's camera and sensors, AR enhances the user's perception of their environment, making it more engaging and informative.
