Abstract
The hand grip of a vehicle steering control rotates about an axis passing through the center of the wrist. Control input is by rotation of the forearm while forces exerted by the operator radially from or parallel to the axis of rotation do not cause control input. A transducer, sensing hand grip position, is restrained only in rotation and isolated from forces acting on the hand grip.
