ABSTRACT:
Light filtering materials, preferably vertical strips of polarizing material, are disposed proximate to a suitably framed two-dimensional image to induce a sense of depth perception. In one embodiment, the image includes a frame disposed around its perimeter, and vertical strips of a polarizing material having a first axis of polarization are placed along the rightmost edge of the image and the leftmost outer edge of the frame, and vertical strips of a polarizing material having a second axis of polarization are disposed along the left edge of the image and along the right outermost edge of the frame. A complementary set of these materials is also supported in eyeglass frames, whereby the right eye sees the left edge of the image but not the right edge of the image or the right outermost strip, and the left eye sees the right edge of the image but not the left edge of the image or appear to recede from the plane of the frame and the frame to come forward relative to the image, thus imparting a dramatic window-like effect. The addition of shadowmasks, which truncate at least a portion of the image may also be used in conjunction with the light filtering materials to further enhance the sense of depth perception.
