Coupled human balancing tasks are investigated based on the pseudo-neural controller modeled by a time-delayed feedback with a random gain. It is shown numerically that compared with single balancing tasks, a mechanical coupling structure increases stability of balancing errors both in amplitudes and velocities and also improves tracking ability of the controller. We then perform an experiment of replacing the pseudo-neural controller of the numerical model with natural human balancing tasks through the use of computer mouse devices. The result shows that the coupling structure yields asymmetric tracking abilities between the subjects whose tracking abilities are nearly symmetric in their single balancing tasks.
