ABSTRACT:
A force-feedback input device includes an operating unit manipulated by an operator, a detecting unit for detecting the operational state of the operating unit, a force-feedback unit for providing a force feedback to the operating unit, and a controlling unit for controlling the operation of the force-feedback unit to provide a predetermined force feedback according to the operational state of the operating unit to the operating unit. The controlling unit includes an operational-state-calculating subunit, a returning-force-calculating subunit, a damping-force-calculating subunit, and a resultant-force-calculating subunit. The damping-force-calculating subunit calculates the damping coefficient by multiplying a returning force calculated in the returning-force-calculating subunit by the required proportionality coefficient and then calculates a damping force by multiplying the obtained damping coefficient by an operation speed of the operating unit.
