(57) ABSTRACT A method and apparatus for interfacing the motion of an object with a digital
processing system includes a sensor for detecting movement of the object along a degree of
freedom. Apassive pneumatic or hydraulic damper is coupled to the object to provide a
damping resistance to the object along the degree of freedom and resist a movement of the
object. The damping resistance is provided by regulating the control of a? uid with a digital
computing apparatus, thus providing a low-cost, low-power force-feedback interface that is …
