Abstract
A kinesthetic feedback apparatus and method whereby braking forces are imposed on a hand-movable lever. The lever is either a joystick or a uniplanar lever, and the braking forces are imposed by a friction plate being pressed against a portion of the lever by a length of magnetostrictive material. An electromagnetic coil around the magnetostrictive material receives a signal from a remote apparatus driven by movement of the lever. The magnitude of the signal is a function of the resistive forces encountered by the remote apparatus so that the braking forces are directly proportional to the resistive forces thereby providing kinesthetic feedback to the person operating the lever.
