ARKit is a software development framework created by Apple that allows developers to build augmented reality (AR) experiences for iOS devices. It combines the real world with digital elements, enabling users to interact with virtual objects as if they were part of their physical environment. Using advanced computer vision and motion tracking, ARKit can accurately detect surfaces, recognize images, and track the user's position. This technology enhances applications in gaming, education, and design, making it easier for developers to create immersive experiences that blend the digital and physical worlds seamlessly.
