Modeling of Human Motor Control and Learning

The neural mechanisms for acquisition of sophisticated motor behavior in humans are very complex. There exists strong evidence in literature that human nervous system may be adaptively tuning internal models of the controlled system dynamics during motor learning. This project investigates existence and formation of internal models during sensorimotor learning by conducting human subject experiments on an underactuated dynamic task with various haptic assistance modes. Studying the aftereffects revealed by the experimental data, the aim of the project is to verify efficacy of several techniques as models of internal model adaptation. Results of this study will enable novel shared control paradigms that improve the rate of internal model adaptation through use of haptic aid. Contributing to basic understanding of human senorimotor behavior, this study has numerous implications in rehabilitation and manual skill training.
