| Outline of Final Research Achievements |
Each of two participants was asked to stand face-to-face two steps apart from each other. Dyads tended to collide or stop each other at the crossing point, if each member stepped forward with the leg contralateral to those of his partner. We then investigated the effect of geometry of the environment on coordination of crossing dyads, and asked dyads to step and exchange their positions under the environment that systematically constrained each member’s stepping DoF. The time lag between two members’ step execution was significantly longer when the spatial DoF was uneven in members, whereas the lag was almost vanished when both members’ DoF were even. These results suggest that step movement might be synchronized in in-phase when both members have same spatial DoF in the action space, and then, if each intends to step forward with contralateral leg to the partner, “unintended crossing coordination” may be inspired that is often experienced in our daily life.
