Abstract: Apparatus for creating the effect of pictures moving in two and three dimensions including a display structure, a number of image producers, and a scanning controller. The display structure contains elements upon which to place the image producers, which elements are arranged in either depth for creating a three-dimensional effect or in width for providing a two-dimensional effect. The image producers can be configured electrodes or surface-covering electrodes used to affect liquid crystal elements of the display structure. Also, the image producers can be radiation sources which cause the images which are to be displayed to become visible to a viewer. The scanning controller is an electronic device which sequentially activates individual members of the image producers to thereby impart the effect of two- or three-dimensional motion depending on the type of display structure utilized.

Abstract: An apparatus for providing a display of information or a source of light to a viewer or an object along the line of sight between a user of the apparatus and the viewer or object without preventing the user's normal vision. The apparatus generally includes an element which provides visible images to the viewer, a member which blocks the visible image from the user, and an activating device which provides oscillating activation signals to the imaging element and the blocking member. The apparatus may also include prisms associated with each other to reflect certain images or light to the viewer or object.
