Tracking users'movements in an artistic physical space

HIPS studies new technologies and interaction modalities that allow people to navigate both a physical space and a related information space at the same time. In this paper we briefly describe the steps from detecting a set of infrared sensors to the building of an internal representation of the visitor behaviour and discuss how this knowledge is employed to build a personalised presentation. In HIPS the Physical Organisation Knowledge Base generalises the notion of space relying on a notion of naive geometry rather the usual Cartesian geometry. A Visiting Style Module estimates the degree of compatibility between the user's movement patterns and four categories. Hence the Presentation Composer builds a new presentation selecting from an existing repository of audio files using knowledge about the visitor's area/orientation in the Physical Organisation Knowledge Base, while information about the Visiting Style is exploited to collect specific information to be delivered to the user
