Augmented Reality (AR) is an emerging technology that enhances the real-world environment by overlaying digitalinformation—such as images, sounds, or data—onto physical surroundings in real time. This study explores the coreconcepts, technologies, and applications of AR across various industries, including education, healthcare, retail,manufacturing, and entertainment. By blending the virtual and physical worlds, AR improves user experience, engagement,and decision-making processes. The research discusses key components such as AR hardware (smart glasses, smartphones),software (AR development platforms), and methods of implementation (marker-based, location-based, and projectionbased AR). Additionally, it highlights the role of AR in immersive learning, remote collaboration, interactive marketing,and real-time diagnostics. Despite its advantages, the technology faces challenges such as hardware limitations, dataprivacy concerns, and user adaptation. The study emphasizes the potential of AR to transform how we interact with ourenvironment and information, predicting its continued growth and integration with complementary technologies likeArtificial Intelligence and the Internet of Things (IoT). Ultimately, AR represents a shift toward more intuitive and contextaware digital experiences that bridge the gap between the physical and virtual worlds.
