We developed a novel ball-shaped interactive transformable robot 〈Column〉 consisting of eight modules that are connected to twelve servomotors for studying the nature of behaviors and communications in our everyday cooperative plays. Three users can control the above servomotors by swinging the wireless modules 〈Gear〉 simultaneously. In this paper, we proposed cooperative play mediated by the Column and evaluated user’s activities and preferences for the play. In the interaction, Column will become a social mediator to prompt the connectivity of the users. In this paper, we attempt to give the development, concept, interaction design content and subjective evaluation experiments. In subjective evaluation experiment, we revealed user’s impressions and preferences for Column’s behaviors and social reference and proficiency level in the cooperative play with Column. We revealed user’s feel more enjoyability to the proficiency level rather than the social reference in the cooperative play mediated by Column. We consider that this result caused by Column’s ability “impatience ”(Modokashisa).
