The SPIRIT concept is based upon a strong storytelling metaphor. By using mobile devices (smartphones, tablets) as "magic equipment", users can meet the restless spirits of historical characters. Beyond the use of mobile technology as a guide, our system enables enjoyable experiences of interactive storytelling, involving users as players. We describe the overall technical augmented reality concept that integrates positioning and media delivery technologies and a framework for structuring interactive narrative experiences. Further, we show our first use scenario that has been developed in collaboration with a Cultural Heritage site, a reconstructed Roman fort and archaeological museum. It includes a first working demonstrator that illustrates issues to be solved as a foundation for defining future work.[Humancentered computing]Mixed / augmented realityInteraction design process and methodsUbiquitous and mobile computing.
