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.
