In order to characterize human gait, a complex and individually different phenomenon, specific measured variables such as distance and temporal factors of foot-floor contact are used, since it is a typical stochastic phenomenon. Using data input devices for computer graphics such as a tablet and a digitizer, we developed a wirelatticed twelve-meter-long walkway and micro-computer software for obtaining position foot stamp data by high-speed sweeping. Previously, we reported the construction of a prototype walkway and the experimental measurement results. In this report, we completed improvement of the system and again collected measuring data. The advantages of the improved system compared to the proto-system are: (a) exchange of micro-computer for a more advanced one; (b) improved switching sensitivity; (c) compact and refined signal sweeping rate electric circuit assemblies; and (d) adjustable Using this system, we collected a number of data concerning normal gait, and introduced general and valid results based upon the statistics. Further, we assessed the right and left symmetricity, the variations of gait parameters and the difference in gait between males and famales.
