Augmented reality (AR) is a technology that integrates digital elements into a user's real-world environment, typically via smartphones, tablets, or specialized AR headsets. It enables interactive experiences by overlaying graphics, data, and other virtual content onto physical surroundings. AR is used across sectors including gaming, retail, healthcare, and manufacturing, offering new ways to visualize information and improve operational efficiency. Investors track AR developments for their potential to drive innovation and market growth.
