In the GEIST project (the term "Geist" is the German expression for the English word "ghost") a system has been developed to educate students and grown-ups in history of a place by offering a personalized and lively tour without a guide. Therefore, technologies and innovative concepts from the areas Location based Services, Augmented Reality Visualisation and Digital Storytelling have been brought together into one system. Using see-through glasses the user gets in contact with the world created by the story. This world consists of a combination of real and virtual objects. The ghosts the user meets here are fictional or historical persons who lead him through his story. To make the real and virtual Objects overlapping each other, a tracking component has to calculate the user's movement through his real environment and transform it to a movement of the users representation in the virtual 3D world. The relation between the two environments is managed in a GIS.
