Abstract
An apparatus for providing a feedback force includes a calculating unit and a force feedback displacement controller. The calculating unit receives relative position information of a first object and a second object and geometric information of the first object and the second object. If the first object and the second object are not in contact, the calculating unit calculates a force feedback value based on the relative position information and the geometric information. The force feedback displacement controller outputs a displacement command, and receives the force feedback value. The displacement command allows the first object to move with respect to the second object. The force feedback displacement controller includes a displacement unit that generates the displacement command based on an operation of a user, and a force feedback unit that provides a feedback force to the displacement unit based on the force feedback value.
