Title: TACTILE SENSE PRESENTATION DEVICE
Abstract:
This tactile sense presentation device 1 is provided with: an operation plate 11 which has an operation surface 100 on which a push operation is performed and is not substantially displaced by a push operation; a piezoelectric actuator 14 which applies vibration to the operation plate 11, generates a squeeze film 140 between the operation surface 100 and an operating finger 9 of an operator, and applies, to the operating finger 9, a floating force F1 in a direction normal to the operation surface 100; a measuring part 13 for measuring the distance L between the operation surface 100 and the operating finger 9; and a control unit 15 which stops the vibration of the piezoelectric actuator 14 when the distance L measured by the measuring part 13 reaches a first distance L1, controls the floating force F1, and presents a tactile sense for the push operation.
