ABSTRACT:
A force-feedback input device comprising an operating section, actuators to supply force-feedback by way of a transmission mechanism to the operating section, a movement quantity detector to detect a quantity of movement of the actuators and a controller to control the actuators by an output from the movement quantity detector. An initializing process is performed by the controller at startup utilizing an output from the movement quantity detector, and an output to the actuators is compensated after startup so that a fixed quantity of force-feedback is supplied to a quantity of movement of the operating section.
