Abstract:
[Object] To provide a haptic presentation apparatus capable of quickly deforming a surface.
[Solving Means] A haptic presentation apparatus includes a base material, an elastic layer, and a fluid transport apparatus. The base material forms a first space and includes a first through hole. The elastic layer covers a surface of the base material including the first through hole. The fluid transport apparatus injects fluid between the elastic layer and the base material via the first through hole. The elastic layer is expanded by injecting the fluid from the fluid transport apparatus such that an internal pressure of a second space between the elastic layer and the base material is higher than an internal pressure of the first space, and the fluid injected into the second space is vented to outside of the second space via a second through hole by stopping driving of the fluid transport apparatus.
