Abstract
Human behavior is affected by some dynamic parameters, which represent the interaction between the body and the environment. In the previous research, a method to extract adaptive components in the behavior has been proposed. This method provides precise reconstruction of behavior using the adaptive components. However, it is not proven that these reconstructed behaviors affect people to perceive the dynamic parameters properly. In this paper, a method to estimate the cognitive scale of the dynamic parameter and a method to extract the characteristic components necessary for perception are proposed. The proposed methods have been applied to loading motion. Those results have suggested that the extracted characteristic components, that is the cognitive index, are not identical with the adaptive components.
