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. A passive 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 fluid with a digital computing apparatus, thus providing a low-cost, low-power force-feedback interface that is safe for the user. The damper and sensor provide an electromechanical interface between the object and the electrical system. A gimbal or other interface mechanism can be coupled between the damper and the object. The interface is well suited for simulations or video games in which an object such as a joystick is moved and manipulated by the user.
