We have developed a gait logging system that can estimate human walking motions with a wearable device attached to the ankles easily. We propose a method to estimate the trajectories of pedestrian accurately using an Inertial Measurement Unit (IMU) and vibration sensor measured at the upper ankles. The estimated trajectories can provide details of gait exercise such as walking distance including the strides of each step. In this paper, we evaluate the walking stride length and velocity on each footstep quantitatively under the different types of footwear. The results demonstrated that our method works well for all footwears. The total walking distances were so accurate (within ± 1% error) that the estimated values of each step were reasonable.
