Tracing the historical development of mixed-mode modelling from a theoretical and practical perspective leads to an understanding of the domain as substantially underpinned by critical social theory. A ‘natural’ progression is discerned, from which it is argued that the logical future direction for mixed-mode modelling is one grounded on theories of communicative action. The beginnings of a fra...

Collaborative media entail an emerging set of digitally mediated practices, characterized by collaborative communicative action within organically developing, cross-medial infrastructures. We argue that computers are increasingly turning from tools into (collaborative) media in everyday use, and that this shift poses a significant challenge to the discipline of interaction design. Particularly ...

Vision scientists are increasingly relying on the point-light technique as a way to investigate the perception of human motion. Unfortunately, the lack of standardized stimulus sets has so far limited the use of this technique for studying social interaction. Here, we describe a new tool to study the interaction between two agents starting from point-light displays: the Communicative Interactio...

We describe the generation of communicative actions in an implemented embodied conversational agent. Our agent plans each utterance so that multiple communicative goals may be realized opportunistically by a composite action including not only speech but also coverbal gesture that fits the context and the ongoing speech in ways representative of natural human conversation. We accomplish this by...

interaction systems engaging in communicative action using a variety of media. There was some interesting discussion about how the resources and constraints of machine communicative partners differ from humanhuman communication. Another important issue was the role of context, which motivated a joint session with the symposium on Context in Knowledge Representation and Natural Language Processi...

While intentions are at the center of communication theories such as Relevance Theory, and also of theories of action in general, the interaction between communicative and non-communicative intentions has not been much investigated within the relevance-theoretic framework. This paper discusses Bratman’s (1987) Theory of Planning, which recognizes the critical role of intentions in governing our...
