ABSTRACT:
A video wall has a plurality of spatial object image display devices, each spatial object image display device including a luminous display screen for providing a first image. The luminous display screen is operably engaged with a video wall computer, which is operatively engaged with at least one video input device such as a video cassette recorder (VCR). The video wall computer acts as a splitter to distribute the output of the VCR to the plurality of spatial object image display devices. Each spatial object image display device also includes a lens operatively spaced apart from the luminous display screen for projecting the first image beyond the lens to appear as a first spatial object. The luminous display screen and the lens of each spatial object image display device are mounted within a housing that surrounds the luminous display screen and the lens, excluding substantially all light from within the housing, except through an aperture in the housing. The lens is operably mounted in proximity to and substantially covering the aperture, operably positioning the lens to project the first spatial object from the housing. The housing further includes a shroud extending from the perimeter of the aperture far enough to shield the lens, but not far enough to surround the first spatial object. All of the spatial object image display devices are covered with a semitransparent screen, and projector is positioned to project a second image onto the semitransparent screen, thereby forming a complex series of images that appear to be three-dimensional.
