Aerial display that reconstructs face orientation by use of spatial blending of two face images.

This paper proposes a novel aerial display system that reconstructs face orientation. The proposed system forms two face images floating in mid‐air. Viewers observe a spatially blended image of the two face images, where the spatial blending ratio depends on the viewing position. Thus, the spatially blended aerial face image is perceived to look in a fixed orientation even if the viewing position is changed within a certain viewing range. We analyze the spatial blending system optical design and show results from our prototype display. [ABSTRACT FROM AUTHOR]
