Abstract:
In order to present a tactile force sense to a user who performs an input operation on a screen of a display panel (20), a tactile force sense presentation device (10) includes a tactile force sense presentation member (11) that transmits a tactile force sense to the user, an actuator (12) that moves the tactile force sense presentation member (11), a vibration generation unit (13) that generates a vibration on the tactile force sense presentation member (11), and a control unit (14). If content on the screen is changed in accordance with the input operation of the user on the screen, the control unit (14) gives the actuator (12) an instruction to move the tactile force sense presentation member (11) such that the tactile force sense corresponding to the change of the content is presented, and gives the vibration generation unit (13) an instruction to generate a vibration such that a vibration is generated on the tactile force sense presentation member (11) simultaneously with start of the movement of the tactile force sense presentation member (11), or before start of the movement.
