We try to quantify the communication in collaborative activities in terms of verbal and non-verbal processes, using collaborators of a creative activity as the study subjects. This study set up a production task using LEGO® blocks. Our study subjects consisted of 5 groups of 3 males. They were asked to use their imagination freely to build a "castle" using the LEGO blocks. We recorded their activities with video cameras, while measuring their bodily movements three dimensionally using a motion capture system. Our experiment showed that the works created by groups with many illustrators (gestures for spatially expressing inner ideas and images) rated high both in perfection level and favorability rating. In a collaborative creation, it was shown that direct visual expressions of mental representations through nonverbal, rather than verbal, communication among the collaborators increased perfection level of the end product.
