Discreteness of Control Points in Human Rising: a Global Dynamics Approach

摘要

In search for design principle of human movement, human rising is experimentally studied using a motion capture device. The variability of each subject's trajectories is analysed, based on a new method of temporal normalisation. As a result, a converging region is found where the body is unstable and control input is necessary. This feature supports our concept of the global dynamics, which suggests control is adopted only unstable regions and rest of parts are supported dynamical or kinematic stabilities.
