ABSTRACT:
An animated holographic stereogram display and method of creating the same is disclosed. In accordance with the method, a user views a hologram from a fixed relative position, the hologram containing a plurality of stereographic image pairs. A plurality of light sources are appropriately spatially dispersed so that each light source will illuminate the hologram so as to make the one stereographic image pair associated with that light source and viewing position viewable by the user. By using stereographic image pairs which are related to each other and appropriate time sequencing of the light sources, animation of the image pairs may be achieved. Uses of the system include facial animation whereby facial image pairs associated with various phonemes may be sequenced in accordance with a speech signal so that a limited set of image pairs may animate the face for a substantially unlimited vocabulary.
