Finding the rhythm: Humans exploit nonlinear intrinsic dynamics of compliant systems in periodic interaction tasks
Fig 5
Pendulum trajectories of Exp. 2 with decreased target radius (↓ rt).
Light-colored lines show the averaged trials per individual participant and the overall averages are dashed for (A) P0 and (B) P90. The left plots compare the red motor link motion θ to the first pendulum link q1 (blue) per period. Middle and right plots compare the respective trajectories in position and velocity space with the NNM.
