: 5 CONCLUSION 
The effectiveness of the HVT System for dynamic analysis of human motion, in particular for human gait 
analysis were investigated through the gait experiments, and it was confirmed that automated tracking were 
performed sufficiently and synchronized stereo image sequences were obtained and rotation parameters for each 
stereo image was acquired in realtime. Furthermore, gait analysis using walking elements obtained by 3D 
coordinates of human feature points were performed efficiently. 
Consequently, it is concluded that the HVT system developed by authors become useful instrument for human 
gait analysis. However, there are some issues, which need to be resolved before the HVT system becomes 
operational in the field of sports training or rehabilitation. These problems include, realtime digital imaging, 
down sizing of the HVT system or so on.
