Evaluation of Social Robot Intelligence in Terms of Social Interactive Motion

In order for social robots to be usably accepted by users, they need to exhibit social interaction skills in a certain degree when they encounter human even in unexpected environments, like human can do. Evaluation of Social Interaction (ESI) is one of well-defined methods to evaluate human social intelligence with 7 classes and 27 items of social interaction skills. Among them, the physically supporting social interaction(PSSI) class with 5 items are dominant to evaluate social robot intelligence, according to the occupation therapist evaluation. In this paper, focusing on the 3 items in the PSSI class, we propose an evaluation method of social robot intelligence in terms of social interactive motion, apply it to a social robot called Wendy and compare it with human social intelligence.
