In this study, it has aimed to presume the dynamic characteristic using a wireless system during human gait locomotion. In general, we install the ground reaction force meter under the floor, and measure the ground reaction forces.

However, it is difficult to measure the floor reaction force of the movement an actual living environment and playing a game by using this system.　Then, in this paper, we try the presumption of the floor reaction force during human gait locomotion by using a wireless tactile sensor system and four CCD cameras.
