Experiment of Interactive Communication Between Human and Robot Based on Emotional Behavior Learning by Using SOM

Abstract

In this research, we conducted the experiment by using torus self-organizing maps (SOM) which generates emotional behavior in order to realize Interactive Emotion Communication (IEC) between human and robot. In this method, we proposed the generation method of various robot emotional motions by using torus SOM, because a robot emotional behavior has been defined uniformly. We were able to realize more complex interaction experiment which a robot expressed the mixed emotion by plural emotions. Finally, we verified how human emotion changes by the interaction experiments with generating mixed emotional behavior. As a result, we confirmed that more complex interaction than the ordinary method was realized and the robot generating mixed emotional behavior grows the interpersonal affinity.
