Today, AR is moving past games and furniture shopping to become foundational to urban life, offering us a glimpse of the high-tech future. Look no further than ambitious Smart City projects globally, especially in places like China. Cities like Hangzhou and Shenzhen are using AR and its related technologies to build sophisticated digital layers over their physical infrastructure: Smart Governance: Using real-time data overlays to manage traffic, energy, and resources (e.g., City Brain). Immersive Culture: Bringing historical sites and museum exhibits to life with interactive 3D projections. Advanced Commerce: Providing AR-enabled retail and seamless location-based information across town.
