A method, system, and computer program product for asynchronous unconscious retrieval retrieves and presents information to end users without requiring the end users to explicitly request the information. In the transport condition, several of the load-bearing rigid surface elements are disposed to form a parallelepiped container having a floor and surrounding rigid walls for accommodating the inflatable flexible surface elements, with the height of the container being lower than the height of the building. The data-side driving circuit is capable of outputting modulation voltages having types of amplitudes to a plurality of first electrodes in accordance with a first display data signal. A series of images and ground for a reference frame are generated from the ground truth and the generated path.
