Distribution of how frequently subjects used one DOF at a time, two DOFs simultaneously, or three DOFs simultaneously as a function of normalized trial duration. (A) Linear regression control. (B) Parallel dual-site control. Both control systems exhibited similar overall strategies, with peak use of simultaneous control near the middle of the trial. Trials ended with greater use of sequential 1-DOF movements. Overall, more simultaneous control was present for all target complexities when using linear regression control compared to parallel dual-site control. Shaded region is standard error.
