The meaning of spontaneous movements
of a recipient in a collaborative work
in face-to-face interaction
When one fi nds something sticking on the face of the other in faceto-
face interaction, the one often instructs the place of the object
with speech and gesture pointing the one’s own body, instead of
pointing the other’s body directly. Such a collaborative work might
be evolved before the mirror self-recognition, because others are
easier to be found than mirrors in natural situation.
To understand the process of this collaborative work, we simulated
it under an experimental situation. Two participants, a recipient and
an informant, sit in a room face-to-face. The recipient put on a helmet
with a small mark, and the informant with speech and gesture
instructed the recipient to move the point fi nger to the mark.
The spatial formats of the informant’s speech and gesture had different
tendencies ; the informant’s speech tended to take the recipient’s
point of view, but the informant’s gesture tends to take informant’s
own point of view. The difference of the spatial format in the two
modalities often causes misunderstanding, but the repair processes
were quick when the recipient moved the fi nger spontaneously.
The informant’s instructions were often ambiguous, and spontaneous
movements of the recipients helped the informant to utter discourse
markers when the recipient’s fi nger came close to the mark.
