Gait IMU with speed label

Cheap MEMS sensors BMX055 were used to obtain the IMU data measurement. Three locations - thigh, shin, and foot were chosen strategically to capture good information about bipedal movement on a single leg. This is in contrast to previous studies, which often use highly accurate and thus expensive sensors. For each location, one BMX055 was used to capture 6DOF information of orthogonal accelerometer and gyroscope.
