The adoption of ubiquitous computing, mobile devices, and rich sources of data are changing how we live, work, and play in urban environments. Increasingly, a digital landscape overlays our physical world and is expanding to offer ever-richer experiences that augment—and in some cases, replace—the physical experience: “The city is the platform, the network, the sensors, and the interface,” as frog creative director Rob McIntosh put it in a recent talk. To celebrate the New Cities Summit where frog hosted a workshop on the Meta-City, design mind presents a special digital issue exclusively on the future of the city and live coverage from the event.
