Abstract: To provide a haptic presentation device that is capable of effectively presenting a haptic sensation to a user. A haptic presentation device according to the present technology includes: a fixed portion; and a deformable portion. The fixed portion is capable of coming into contact with a body of a user. The deformable portion includes a first side that is a side closer to the fixed portion and a second side that is a side farther from the fixed portion and has rigidity lower than rigidity of the first side, and is capable of coming into contact with the body of the user by deformation.

Abstract: [Object] To provide a technology capable of presenting various haptic sensations to a user.
[Solving Means] A haptic presentation apparatus according to the present technology includes: a first deformable layer; a second deformable layer; and a drive unit. The first deformable layer is positioned on a front surface side. The second deformable layer is positioned inward of the first deformable layer. The drive unit is driven to control outflow and inflow of fluid between a first space and a second space, the first space retaining the fluid between the first deformable layer and the second deformable layer, the second space retaining the fluid inward of the second deformable layer.

Abstract: In order to provide a tactile presentation apparatus and a tactile presentation system that are capable of presenting a high-quality tactile sense with shape and pressure distribution controlled with respect to a contact object, a tactile presentation apparatus according to the present technology includes a contact portion, a peripheral portion, a retaining portion, a first driving portion, and a second driving portion. The contact portion includes a central portion having a first contact surface and a connection portion having a second contact surface, the second contact surface being flexible and continuous with the first contact surface. The peripheral portion is connected to the central portion through the connection portion. The retaining portion that supports the contact portion and the peripheral portion. The first driving portion changes a height of the central portion from the retaining portion in a first direction in which the central portion gets away from the retaining portion and a second direction and changes a press force to the central portion in the first direction in accordance with the height of the central portion from the retaining portion, the second direction being a direction opposite to the first direction. The second driving portion changes a height of the peripheral portion from the retaining portion in the first direction and the second direction and changes a press force to the peripheral portion in the first direction in accordance with the height of the peripheral portion from the retaining portion.

Abstract: A fluid control apparatus includes a flow-path space forming portion, an inflow opening, an outflow opening, and a drive mechanism. The flow-path space forming portion includes a flexible portion that have flexibility, and a facing portion that faces the flexible portion, the flow-path space forming portion forming a flow path space between the flexible portion and the facing portion, the flow path space being a flow path of fluid. The inflow opening is provided to an outer peripheral portion of the flow path space, as viewed from a facing direction in which the flexible portion and the facing portion face each other, the inflow opening being an opening through which the fluid flows into the flow path space. The outflow opening is provided to a portion, in the outer peripheral portion of the flow path space, that is different from a portion, in the outer peripheral portion of the flow path space, that is provided with the inflow opening, as viewed from the facing direction, the outflow opening being an opening through which the fluid flows out of the flow path space. The drive mechanism bends the flexible portion to increase or decrease the volume of the flow path space. Further, the flexible portion is configured such that at least a portion of a region of the flexible portion is curved toward the facing portion to have a concave shape in a reference state in which the flexible portion is not bent by the drive mechanism, the region of the flexible portion being situated further inward than the outer peripheral portion of the flow path space, as viewed from the facing direction.

Abstract: A shape changeable apparatus according to an embodiment of the present technology includes a space forming section, a fluid controller, a signal emitter, a detector, and a generator. The space forming section forms a space, and includes a deformable member that is arranged in contact with the space. The fluid controller is capable of deforming the member by controlling a flow of fluid with respect to the space. The signal emitter emits a signal into the space. The detector is arranged out of contact with the member within the space, and detects the emitted signal. The generator generates information regarding the deformation of the member on the basis of a result of the detection performed by the detector.
