Force sense presentation device, force sense presentation system, and force sense presentation method

A force sense presentation system, comprising:

• a force sense presentation device that includes
• a movable body,
• an actuator unit connected to the movable body, and
• a posture detection unit configured to detect posture of the force sense presentation device;
• a signal generation unit configured to generate a driving signal for generating vibration on the actuator unit, the vibration having within a period at least one of a plurality of different amplitudes and a plurality of different frequencies;
• a control unit configured to control the generation of the driving signal by the signal generation unit depending on the detected posture.
