Data of pressure sensors and accelerometer under smart insole

Dataset of a smart insole that are used to estimating stride length. Eight participants wore a pair of smart insoles and Gait Up. For a period of six minutes, each participant walked back and forth on a predefined 20-meter pathway in the indoor setting, and the numbers of round trips and strides taken were counted. The smart insole is equipped of five pressure sensors and one 3D accelerometer. The actual total distance was calculated by multiplying the number of round trips by 40 meters. Two stride length estimation approaches based on the director coefficients of acceleration data (Approach-1) and Dynamic Time Warping (Approach-2) using smart insoles were used.
