Computations in Human Sensorimotor Control
The effortless ease with which humans move our arms, our eyes, even our lips when we speak masks the true complexity of the control processes involved. This is evident when we try to build machines to perform human control tasks. While computers can now beat grandmasters at chess, no computer can yet control a robot to manipulate a chess piece with the dexterity of a six-year-old child. A major factor that makes control hard is the uncertainty inherent in the world and in our own sensory and motor systems. Sensory and motor uncertainty form a fundamental constraint on human motor control. I will introduce the fundamental concepts involved in Bayesian Decision Theory and how they can be applied to understand human motor control. I will describe experiments that show that humans use Bayesian inference to make estimate during motor tasks and how we estimate the loss function of our movement. I will then describe how prediction of the consequences of our actions can be used to reduce uncertainty, and present experiments on tickling which elucidate this predictive mechanism. Finally I will describe how signal-dependent noise on the motor output places constraints on performance. Given these constraints the features of goal-directed movement, such as the eye and hand trajectories, arise from a model in which the statistics of our actions are optimized. Taken together these studies show that probabilistic models play a fundamental role in human sensorimotor control.
