Outline of Final Research Achievements

The results of a gap-passing experiment using an electric wheelchair suggest that there is a bias in the distribution of the gazing point of an actor approaching a gap and that there is a link between the bias of the gazing point and the trajectory control of the motorized wheelchair, although the causal relationship between them cannot be determined. Next, we investigated how the optical flow of the entire visual field (global flow) experienced by a person as he or she moves through the environment affects the detection of objects in the visual field (local flow) by means of stimulus images presented on a computer display. The results suggest that the gaze is focused on a specific part of the edge of the local optical flow and that the direction in which the gaze is focused is influenced by the global optical flow.
