A gaming interface using body gestures for collaborative navigation

We designed a collaborative navigation interface in which one user (the controller) guides a second, remote user (the navigator) through a 3D game environment. Both sides of the interface use commercially available gaming hardware. The controller uses full-body gestures to send navigation cues to the navigator, who travels through the environment using typical 3D gaming controls. In an exploratory study, all participants completed the game scenario, and they viewed the system as usable and fun overall, although the limited communication provided by the system was somewhat of a hindrance to collaboration. Navigators, who were led to believe they were being guided by an intelligent system, did not guess that guidance was provided by another human, and felt that an "intelligent system" would typically be more consistent than a human being.
