Occlusion Displays

  • Reference work entry
Handbook of Visual Display Technology

Abstract

The occlusion capability of a see-through display is important in enhancing user’s perception, visibility, and realism of the synthetic scene presented. Unlike video see-through displays, occlusion of a real scene in an optical see-through fashion is quite difficult to achieve, as the real scene is always seen through the partially transmissive optical combiner. In this article, four portions in ray paths of an optical see-through display are first identified between the light source and the eye. Corresponding to them, a number of existing approaches for an occlusion display are then introduced that cut off the light in a different manner. Finally, recent advancements and future directions of occlusion displays are discussed.
