Abstract
This paper proposes the novel method for supporting the communication of "Ba" on site by using aerial drawing system combined with the physical expression activities. In this method, in order to develop a relationship between two users and extract the bodily expressions together, this system connects the band-shaped 3DCG between each of hands and generates the trajectory as a surface-shaped CG during dancing jointly. Moreover, after the bodily expressions the solid object representing the relationship is made by overlapping all surfaces. Then the 3D objects are projected on a translucent cloth with which the participant was covered, and consequently we developed the method that the object not only was demonstrated the relations with the object floating in the air, for the participant under the cloth, but also made their sense like being wrapped in the expression. At last, we applied these systems to some workshops which general participants take part and confirmed the effectiveness to the possibility of extract a new expression of the participants.
