Figure 2

Analysis of pure frequency curves using the movement element decomposition method. Data is shown for ν = 3 (panel A), ν = 4/3 (panel B), ν = 4/5 (panel C), and ν = 0 (panel D). Each panel shows the traces detected by a camera-based motion capture system (left plot) and the log-log plot of the absolute value of the velocity of the movement elements vs. the corresponding displacement values (right plot) for one subject. The latter shows that the movement elements for all the pure frequency figures obey the power-law shown in Equation 6.
