Augmented reality (AR) applications on mobile devices operate using a combination of the device’s camera, sensors, and software to overlay digital content onto the real world. By recognizing physical environments, AR apps enhance user experiences by integrating virtual elements, such as information or graphics, in real-time. This technology opens avenues for interactive gaming, education, and marketing, enabling users to engage with content dynamically and contextually, bridging the gap between physical and digital realms.
