Abstract
Some researches in the field of human symbiotic system and human-agent interaction have been actively performed. It becomes a background that the flexible understanding ability for human intent and the expressing ability of robot intension are required for the robot to live together with human. However the technology for realizing bidirectional communication between a human and a robot has not been established yet, therefore there are very few robots which are able to communicate to human smoothly. Therefore, the interactive emotion communication (IEC) -bidirectional interaction based on emotional behavior between a human and a robot has been proposed. We aim to give high interpersonal affinity to the robot for the amplification or relief of human emotion though the interaction by communicating emotional behavior mutually. In this research, we proposed the generation method of various robot emotional motions by using self-organizing maps because a robot emotional behavior has been defined uniformly until experiments. As a result, we were able to realize more complex interaction experiment which a robot expressed the mixed emotion by plural emotions. Next, we confirmed how human emotion changes by the interaction experiments with generating mixed emotional behavior. In consequence, more complex interaction as compared with the ordinary method was realized and the robot generating mixed emotional behavior became to grow the interpersonal affinity.
