There is a pretty cool National Geographic road show touring shopping centres in Hungary right now, an augmented reality installation that lets the thousands of people passing by interact with the type of content they would find on the National Geographic channel, from dolphins and dinosaurs to leopards, spacemen and lots more.
It works by placing a huge digital screen and high-powered camera in front of an AR marker that is stuck to the ground. As people step onto the marker, the content comes alive on the big screen in front of them. A neat little trick here was having what looked like a park ranger (or something!) who was there to help people interact with the augmented reality content and make the whole installation a little more interesting.
