We interact with others even without utterances, because observation of others’bod-ily motions often enables guessing their intentions. Others’bodily motions serve as amajor resource for mutual action and collaboration. In this article, we have analyzed,qualitatively with multimodal and fine-grained transcripts, “implicit collaborations”that are constituted by not only utterances but also bodily motions, and have revealedthe way people organize those. The example domain we have selected is a table cookingof “monja-yaki”, because implicit collaboration occurs frequently during cooking. Ourfindings are the following: (1) reading appropriate timing based on observations of eachother’s bodily motions made smooth transitions of cooking phases successful, and (2)even when the current speaker, addressing a certain hearer, asked a question and the hearer did not make an oral reply, the lack of reply did not cause any problem in theircommunication if the hearer intended to reply by his or her bodily motions, and thespeaker properly attended to those. This way, communication and/or collaborationhold even without oral turn-taking.
