@inproceedings { leite10, abstract = {The ability of artificial companions (virtual agents or robots) to establish meaningful relationships with users is still limited. In humans, a key aspect of such ability is empathy, often seen as the basis of social cooperation and pro-social behaviour. In this paper, we present a study where a social robot with empathic capabilities interacts with two users playing a chess game against each other. During the game, the agent behaves in an empathic manner towards one of the players and in a neutral way towards the other. In an experiment conducted with 40 participants, results showed that users to whom the robot was empathic provided higher ratings in terms of companionship.}, affiliation = {INESC-ID and Instituto Superior Técnico, Av.
