Abstract

In this paper we present a qualitative spatial relation formalism capable to represent spatio-temporal knowledge. To this aim, we have added the notion of time within the formalisation of spatial relations in order to describe moving graphical objects. As a case study, we exploited this augmented formalism to support a qualitative specification of gestures, which are an increasingly relevant issue in the human-computer interaction field. The resulting technique provides gesture specification with a systematic and formal foundation.
