Augmented Reality (AR) is a technology that enhances a user's perception of the real world by overlaying digital information - such as images, sounds, or interactive data - onto their physical environment. Unlike virtual reality, which creates a completely artificial experience, AR blends digital elements with real-world surroundings in real time. This is commonly achieved using smartphones, tablets, or specialized AR glasses, allowing users to see and interact with virtual objects as if they were part of the real world. AR is used in gaming, education, navigation, and professional fields like healthcare and engineering to provide immersive, context-aware experiences.
