Abstract: Successful collaboration requires interaction partners to constantly monitor and predict each other’s behavior to establish shared representations of goals and intentions. In human-robot interaction (HRI) this aspect is particularly challenged by ongoing technical limitations in robot perception and reasoning about the human partner’s behavior and underlying intentions. The human partner on the other hand is not just capable of judging the robot behavior but also to oversee the overall interaction performance. Studies have demonstrated that erroneous or unexpected robot actions engage error-/performance processes in the human partner’s brain, which manifest as error-related potentials (ErrPs), observable and reliably decodeable using non-invasive electroencephalography (EEG). Real-time decoded ErrPs constitute a valuable source of information about the human partner’s expectations and subjective preferences and therefore could serve as a useful complement to existing methods for validating and improving HRI or human-machine interaction in general. This talk introduces the current state-of-the-art along this line of research and follows with the presentation of our recent study demonstrating the usability of ErrPs for mediating co-adaptation in the context of a simplified social interactive human-robot interaction task. The second part of the talk is concerned with computational modelling of the human partner’s decision-making behavior in the given context. The latter serves as a simulation-based approach to disentangle potential factors influencing convergence in ErrP-based human-robot co-adaptation.
