The term "augmented reality" (AR) refers to an interactive experience where computer-generated elements are superimposed onto the real world. This technology enhances the user's perception of their environment by overlaying digital information, such as graphics, sound, and other sensory enhancements. AR can be experienced through various devices, primarily smartphones and smart glasses. Applications range from gaming, like Pokémon GO, to training simulations in industries such as healthcare and manufacturing. By blending virtual and real-world elements, AR creates immersive experiences that enhance both entertainment and productivity.
