Manipulability metrics are used to evaluate the feasibility of a vehicle occupant package design. A manipulability metric quantifies the ability of a virtual human subject to carry out an operational task in the design. Examples of specific manipulability metrics include a force metric quantifying the subject's ability apply a joint torque as a force to a component of the design, a velocity metric quantifying the subject's ability to cause the component to achieve velocity, and a dynamic metric quantifying the subject's ability to cause the component to achieve acceleration. Manipulability metrics are determined using a Jacobian determined as part of a determination of a posture of the subject carrying out the task. The manipulability metric is further determined using an endpoint direction of motion and a combination differential kinematics and static equilibrium considerations.
