Robot behavior control system based on user's attitude using SCL

In order to have simple conversations between users and companion robots, it is necessary that robots evaluate the user's attitude. We developed a robot behavior control system utilizing a user's skin conductance level (SCL). SCL is used as an indication of physiological arousal. This system controls the time the robot remains in one program based on the user's arousal level before changing topics. In the results, we found several tendencies of the user's response based on the SCL. We suggest a possibility for utilizing a user's physiological data to communicate with a robot.
