Human gait (way of walking) can be changed to correspond to human gaze direction. We aim to realize a gait-based gaze estimation scheme by modeling the relations between gait and gaze. In this paper, as a first step to our goal, we show the preliminary analysis results of the relations between gait and gaze. From the results, we confirmed that arm swing is affected by the gaze direction. We confirmed a tendency for the opposite arm's amplitude in the gazing direction to decrease. For these analysis, we constructed an immersive walking environment in which we measured subject gaits in various gazing situations by a motion capturing system and an eye tracker. The environment consisted of a treadmill and 180 multi-screens for presenting the gazing target. Our analysis results suggest the possibility of gaze estimation based on gait.
