Infant-Like Social Interactions Between a Robot and a Human Caregiver

Abstract

From birth human infants are immersed in a social environment that allows them to learn by leveraging the skills and capabilities of their caregivers. A critical pre-cursor to this type of social learning is the ability to maintain interaction levels that are neither overwhelming nor under-stimulating. In this paper we present a mechanism for an autonomous robot to regulate the intensity of its social interactions with a human. Similar to the feedback from infant to caregiver the robot uses expressive displays to modulate the interaction intensity. This mechanism is integrated within a general framework that combines perception attention drives emotions behavior selection and motor acts. We present a specific implementation of this architecture that enables the robot to react appropriately to both social stimuli (faces) and non-social stimuli (moving toys) while maintaining a suitable interaction intensity. We present results from both face-to-face interactions and interactions mediated through a toy.
