Pfeiffer-Leßmann N, Wachsmuth I. Formalizing joint attention in cooperative interaction with a virtual human. In: Mertsching B, Hund M, Aziz Z, eds. KI 2009: Advances in Artificial Intelligence. Vol LNAI 5803. Berlin: Springer; 2009: 540-547.Crucial for action coordination of cooperating agents, joint attention concerns the alignment of attention to a target as a consequence of attending to each other’s attentional states. We describe a formal model which specifies the conditions and cognitive processes leading to the establishment of joint attention. This model provides a theoretical framework for cooperative interaction with a virtual human and is specified in an extended belief-desire-intention modal logic
