Human perceptual-motor coordination in unknown dynamical environments

This paper investigates how a human learns the perceptual-motor coordination to adapt to his/her unknown dynamical environment while performing a required task. We focus on a specific task of turning a crank. The crank's size and its center are unknown and can be adjusted. An AC motor was equipped to change the crank's dynamics. A head mounted display provides the subjects with various visual information. We find that human movements exhibit different performance under different visual information conditions. We suggest that humans utilizes visual information effectively in adapting to unknown dynamical environment.
