Human perceptual-motor coordination in unknown dynamical environments

This paper investigates how human learns perceptual-motor coordination to adapt to his/her unknown dynamical environment during 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 concerning different visual information conditions. We suggest that human utilizes effectively visual information in adapting to unknown dynamical environment.
