Inferring limb coordination strategies from trajectory kinematics.
This paper discusses the method of kinematic modeling and matching to human arm trajectories in order to ascertain the motor control system's coordination strategy. The planning variables of joint angles and endpoint Cartesian coordinates are contrasted, under linear and staggered interpolation strategies. It is shown that distinguishing the two variable planning sets depends critically on the region of the workspace in which movement takes place.
