Recent studies of interaction research have revealed that mind in the interaction is
embodied in gesture in the material world as the interaction resource. In this study,
we research interaction of turning pages each other when they decide the order of the
restaurant. Using a virtual menu with 6 pages, 2 participants in the experiment decided
to take one dish for each one for each page. Focusing on when and how the partici-
pants turn each page, we found that both participants touch or follow the page when
it was turned in 64/135 cases. The timing of the turning is organized not only by their
utterance of announcing their order but also the body movement of page manipulation.
They used the spatio-temporal pattern of page manipulation such as moving their hand
from the center to the edge of the page or lifting the edge of the page slightly. These
pre-sequences of turning pages, which were step by step process of sequential move-
ments with pauses and were embodied with material world of the page structure, seem
to project the next movement of page manipulation to prepare the simultaneous page
turning by the participants.
