In this demonstration we show how situated multi-party human-robot interaction can be modelled using the open source framework IrisTK. We will demonstrate the capabilities of IrisTK by showing an application where two users are playing a collaborative card sorting game together with the robot head Furhat, where the cards are shown on a touch table between the players. The application is interesting from a research perspective, as it involves both multi-party interaction, as well as joint attention to the objects under discussion.
