A visual digital recorder system (DVR) is widely used to visualize and analyze the dynamic image of moving body. The instrumentation system of the DVR is applied to study and analyze two-dimensional moving images of the walking human body. However, studies of dynamic behaviors on human body are very little. In this paper, dynamic behaviors of human body segments like location and velocity of walking human bodies are visualized and measured using DVR. Fluctuation characteristics of frequency f, power spectrum density PSD and coherence C of five young and old persons were quantitatively analyzed and evaluated for four segments of each person. Lastly, it was concluded that fluctuation performances of the moving human body were largely influenced by person age.
