Three-dimensional motion analysis of human gait
Objective:
Walking is fundamental human movement. The objective of our studies of walking is to understand the role of perceptual (especially visual) systems on the control of human gait. The experiments are designed on the basis of the methodology of experimental psychology. The system of three-dimensional motion analyses is used to measure whole-body movement during walking. Dynamical changes in space were designed to occur in an experimental room by using adjustable movable doors.
Apparatuses:
A three-dimensional motion capture system (Qualisys Inc.); a customized movable door (Uchida Denshi Inc.); an LCD shutter goggle (PLATO, Translucent Technologies Inc.); and accelerometers (Microstone Inc.).
Research topics:
- Perceptual-motor control of locomotion through apertures
- Asymmetry of spatial cognition during walking
- Obstacle avoidance during walking
- Three-dimensional motion analysis of walking by visually impaired individuals
