A display control apparatus includes a display control section that generates a virtual space image by specifying a viewpoint position and a direction of line of sight and displays the image on a head-mounted display. The display control section can specify a plurality of positions in the virtual space as viewpoint positions and can change the viewpoint position to a position determined from among the plurality of positions in accordance with an attitude of the head-mounted display, and when the viewpoint position is changed, the display control section specifies, as a direction of line of sight, the direction in which a first position in the virtual space is seen from the changed viewpoint position.

Example implementations relate to a pivoting plate flexible display. For example, an apparatus includes a flexible display device and a support structure adjacent to the flexible display device. The apparatus also includes a pivoting plate device coupled to the support structure, where the pivoting plate device is capable of pivoting about a central connector connected to the support structure to allow the flexible display device to transform from a flat configuration to a curved configuration.
