Abstract: Coupled human balancing tasks are investigated based on both pseudo-neuralcontrollers characterized by time-delayed feedback with random gain and naturalhuman balancing tasks. It is shown numerically that, compared to singlebalancing tasks, balancing tasks coupled by mechanical structures exhibitenhanced stability against balancing errors in terms of both amplitude andvelocity and also improve the tracking ability of the controllers. We thenperform an experiment in which numerical pseudo-neural controllers are replacedwith natural human balancing tasks carried out using computer mice. The resultsreveal that the coupling structure generates asymmetric tracking abilities insubjects whose tracking abilities are nearly symmetric in their singlebalancing tasks.
