ABSTRACT
Introduction Many human actions occur in social contexts in a variety of situations. Simple examples of interpersonal interaction involve establishing a conversation, manipulating objects, dancing or walking together. Previous research in cognitive and psychological sciences has shown that interpersonal interaction tends to be coordinated (Schmidt & O’ Brien, 1997). This phenomenon implies several co-adaptive behaviours from one person relative to another person, including for instance eye or limb movements. Interestingly, people seem to achieve interpersonal coordination in a very natural way without much effort, even unintentionally (Richardson et al., 2007). So how does interpersonal coordination work, and how can we model it?
