Figure 1

Analysis of the trajectories of motion performed by a subject while drawing ellipses of different sizes. Data for ellipses of different sizes is shown in different colors. (A) Trajectories of motion; (B) log-log plot of the instantaneous velocity vs. the curvature of the trajectory of motion: (C) x-component of the velocity of movement during one repetition of the drawing movement for each ellipse; and (D) log-log plot of the mean of the absolute value of the velocity for each movement element and the associated displacement (the line represents the power-law shown in Equation 6).
