During Arbor Day Weekend QR codes were seeded across New York City’s Central Park, transforming it into a mobile interactive experience. The QR codes we formerly used to transform secret messages in public space in Amsterdam are up to a new stage of development. They give access to an Augmented Reality here. With iPhones and other web-enabled smart-phones and a QR code reader, users could explore the world’s most famous park in a totally different way. The movie below shows the trans-reality that is added to the regular park atmosphere. A new digital layer of reality merges with the actual park.
