Description

ABSTRACT:
A video display system provides low cost, rapid processing for a high volume of participants through an interactive video system. The system includes a darkened serpentine tunnel constructed of flat faceted rear projection screens, formed as series of multi-screen sections. Video imagery is projected onto the screens from video projectors using reflecting mirrors on the back sides of the screens. The screens are mated together to form the complete tunnel. Participants travel through the darkened tunnel riding in guided vehicles. As each vehicle progresses through the tunnel, the projection screens currently surrounding the vehicle are illuminated, together with the preceding and succeeding screen sections. As the vehicle transitions from the current section to the forward section, the rearward section is extinguished and the next forward section illuminated. The image intensity of the forward section is gradually increased as the vehicle approaches, by virtue of the gain characteristics of the projection screen, thus making the transition nearly undetectable.
