Virtual Partner Interaction (VPI): Exploring Novel Behaviors via Coordination Dynamics

Abstract: Inspired by the dynamic clamp of cellular neuroscience, this paper introduces VPI—Virtual Partner Interaction—a coupled dynamical system for studying real time interaction between a human and a machine. In this proof of concept study, human subjects coordinate hand movements with a virtual partner, an avatar of a hand whose movements are driven by a computerized version of the Haken-Kelso-Bunz (HKB) equations that have been shown to govern basic forms of human coordination. As a surrogate system for human soci… Show more

“…In this paradigm a human interacts in real time with a computationally implemented theoretical model of him-or herself called a VP (24). Initial work demonstrated the feasibility of an HDC for coordination of rhythmic movements through the embedding of the HKB model.…”

“…The HDC balances ecological validity with the constraints of neuroimaging (9) by allowing full control of chosen parameters from one of the interacting agents, while at the same time preserving interaction and reciprocity. It thus may become a tool for the neurobehavioral investigation of social behavior, especially for uncovering essential nonlinearities in social behavior such as turn taking, transitions between cooperation and competition, and the neural underpinnings of attribution of intention in interactive contexts (24,43).…”

“…These measures can potentially, in particular in the case of imperfect and dyadic coordination, indicate when one individual is more influenced by the other. To this aim, but in terms of experimental paradigm, another way to break the symmetry of measures and protocols is by use of the concept of the human clamp project, the virtual interacting partners (VPI; Kelso et al, 2009). By manipulating the parameters, intrinsic dynamics, and coupling function, of an artificial interacting agent, one may reveal hidden properties of the human actor.…”

“…By manipulating the parameters, intrinsic dynamics, and coupling function, of an artificial interacting agent, one may reveal hidden properties of the human actor. Kelso et al (2009) judiciously reversed the coupling function within the artificial agent, to create a conflict between the human and the VPI and investigate novel phenomena. In the same vein, this insight about individual’s role within a pair can be examined by breaking the symmetry of movements, for instance by changing the moment of inertia of hand oscillated pendulum (Varlet et al, 2012), but more radical differences can be introduced.…”
