Figure 4

Analysis of three-dimensional movement data. Panel A shows an example of movement trajectories recorded during the performance of arm movements to reach and transport a can of soda (n = 1). Panel B shows an example of trajectories recorded during the performance of random movements. Panel C shows the absolute value of the velocity of the movement elements vs. the corresponding displacement values for the movements shown in the other two panels. The plot shows that the movement elements for all three-dimensional movement data obey the power-law shown in Equation 6.
