| Outline of Final Research Achievements |
The purpose of the present study was to investigate locomotion through apertures with three-dimensional motion analyses and to understand how accurate spatial perception necessary for locomotion is achieved. The main findings are summarized as follows: (a) the central nervous system is likely to determine the amplitudes of shoulder rotations to ensure the minimal spatial margin being created at one side of the body at the time of crossing, (b) dynamic visual information, referred to as optical flow, is likely to improve perception of the relationship between body and environment during locomotion, but not perception while sitting at a distant place from an aperture, (c) the behavior of body rotation, which is necessary to avoid collision, is executed at least two steps before crossing the aperture, (d) some brain functions in their left brain hemisphere, such as parietal and premotor cortices, may play a more important role in controlling walking trajectory.
