IMU-based gait region identification. In the first plot, the initial signal is shown. For the detection of gait events in the specific dataset, the gyroscope’s Z-axis signal was employed. Next, in the second plot, the result of the procedure for the detection of walking bouts appears, with the region of interest highlighted. In our work, the regions were extracted manually. Finally, in the third plot, the results of the peak detection method can be seen. The peak detection method was used to identify gait events.
