Skilled motor control of an inverted pendulum implies low entropy of states but high entropy of actions
Fig 10
Distribution of key presses in the balancing region for three trials and distance traveled by the pendulum during the key presses.
Blue segments represent actions that push the pendulum in the clockwise direction, red segments indicate actions that steer the pendulum towards the anti-clockwise direction. Key presses (“balancing episodes”) are reported subsequently from the top to the bottom of the plot. In (a) and (b) the key presses of two skilled participants are reported, where in (c) the key presses of a less skilled participant is shown.
