A system for real-time updates to a display based upon the location of a camera or a detected location of a human viewing the display or both is disclosed. The system enables real-time filming of an augmented reality display that reflects realistic perspective shifts. The display may be used for filming, or may be used as a “game” or informational screen in a physical location, or other applications. The system also enables the use of real-time special effects that are centered upon an actor or other human to be visualized on a display, with appropriate perspective shift for the location of the human relative to the display and the location of the camera relative to the display.
