The term augmented reality refers to a technology that overlays digital information and virtual elements onto the real-world environment, enhancing the user's perception and interaction with their surroundings. This is achieved through devices like smartphones, tablets, or AR glasses that integrate real-time images with computer-generated graphics. Use cases include gaming, training, education, and marketing, where augmented reality provides immersive experiences, enabling users to visualize information in a meaningful context and fostering deeper engagement.
