Screenshot of the annotation software. Layered display of: 1. 3D motion (gray spheres); 2. 2D-graphs showing evolution in time of the COM coordinates (blue = x, purple = y, pink = z); 3. Annotations (red vertical lines and labels). 4. GUI (blue windows, allowing navigation in the file, and label edition). In this example, G06 has been annotated, and G07 is being annotated. For G06, labels are placed when the z-axis of the COM is low, and for G07, labels are placed when the COM y-axis if low (COM is on the left) or high (COM is on the right).
