The technology pivotal for developing augmented reality (AR) applications includes computer vision, 3D modeling, and software development kits (SDKs) like ARKit and ARCore. Computer vision enables devices to interpret and understand the physical environment, allowing digital overlays to be accurately rendered on real-world views. 3D modeling provides the graphical assets necessary for AR experiences. Together, these technologies facilitate engaging user interactions by blending virtual elements with the physical world, enhancing various applications in gaming, education, and retail.
