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.

本数据集记录了一款智能鞋垫的使用情况，该鞋垫用于步长估计。八名参与者分别佩戴了一对智能鞋垫及Gait Up设备。在室内预设的20米路径上，每位参与者在六分钟的时间内往返行走，并记录了往返次数及步数。智能鞋垫配备有五个压力传感器和一个3D加速度计。实际总距离通过往返次数乘以40米计算得出。本数据集采用了两种基于加速度数据导数系数的步长估计方法（方法-1）以及基于智能鞋垫的动态时间规整（方法-2）进行步长估计。
