Ronald Lenz from 7scenes discusses how mobile technologies are transforming cities. Mobile apps and location-based services allow for new forms of connected experiences and storytelling. 7scenes is a mobile storytelling platform that makes it easy to publish location-based content for travel, tourism, heritage sites, and more. It provides authoring tools, community features, and apps for iPhone, Android and Nokia. Examples of 7scenes projects include cultural "TomToms", mobile tours and games for parks, and guided city explorations for events and festivals. The future may see cities functioning as operating systems with open mobile platforms enabling new collaborations and business models.
