Multi-dimensional interactive city exploration through mixed reality

In this paper we present a pervasive outdoor mixed reality edutainment game for exploring the history of a city in the spatial and the temporal dimension, which will closely couple the real environment with the virtual content. The game provides a new and unique user experience, which links rich interactive content to time and places. We introduce the development of such a game, including a universal mechanism to define and setup multi-modal user interfaces for game challenges.
