PROBLEM TO BE SOLVED: To provide a force sense presentation system capable of reproducing force sense when a remote object or a virtual object is handled by hand with simple configuration, structure, and control system.SOLUTION: An operation unit 10 comprises: an operation part 12 having a displacement part 12b; a rotation resistance generation device 50; and a displacement amount detection part 14 for detecting a displacement amount of the displacement part 12b. The rotation resistance generation device has a rotation shaft for rotating in linkage to displacement operation of the displacement part, and is configured to change strength of magnetic field which is applied to a magnetic viscous fluid included inside by change of a current value of supplied current, and change rotation resistance of the rotation shaft. A following unit 20 comprises: a following part 22 for displacing according to the displacement amount detected by the displacement amount detection part; and a reaction force detection part 23 for detecting reaction force to the following part generated by contact of the following part 22 to a target object. In addition, a control part 21 for controlling a current value to be supplied to the rotation resistance generation device according to the reaction force detected by the reaction force detection part, is further included. |
