ARCore is a software development kit created by Google that enables developers to build augmented reality (AR) applications for Android devices. It uses advanced technology to understand the environment, track motion, and place virtual objects in the real world. This allows users to interact with digital content as if it were part of their physical surroundings. The platform supports various features, including motion tracking, environmental understanding, and light estimation. By leveraging the capabilities of modern smartphones, ARCore enhances user experiences in gaming, education, and retail, making it easier to blend digital information with the real world.
