Computer vision localization used for mixed reality multiplayer game in German city

Sixty people participated in a multiplayer augmented reality game in Cologne, Germany. The game allowed participants to interact with virtual versions of Cologne's landmarks from different historical periods, providing them with a new way to learn the city's history that is very different from the typical interpretive tour. Computer vision techniques for spatially localizing landmarks were key to enabling the experience.

The game was part of the IPCity project. More information can be found in a physorg.com article.
