| Outline of Final Research Achievements |
The purpose of this study was to elucidate the regularity and principle mechanism of human movement, based on non-autonomous dynamical systems theory. Specifically, we focused on the integration of dissipative and continuous dynamical systems when a human is constrained to switch directions in response to an external spatio-temporal input. The experimental tasks investigated included a kick-motion (shot-motion), in which one motion is repeated, and a catch-and-throw motion, an example of two integrated movements. The results showed: 1) fractal-like or self-similarity structure in the switching motion patterns and 2) fractal transitions in the mappings as the frequency of the motion (the number of kicks or catch-and-throws) increased.
