Public displays of affect: deploying relational agents in public spaces

Design principles for deploying agents designed for social and relational interactions with users in public spaces are discussed. These principles are applied to the development of a virtual science museum guide agent that uses human relationship-building behaviors to engage visitors. The agent appears in the form of a human-sized anthropomorphic robot, and uses nonverbal conversational behavior, empathy, social dialogue, reciprocal self-disclosure and other relational behavior to establish social bonds with users. The agent also uses a biometric identification system so that it can re-identify visitors it has already talked to. Results from a preliminary study indicate that most users enjoy the conversational and relational interaction with the agent.
