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.
