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. A novel aerial display is proposed to reconstruct the face orientation. The proposed system forms two face images floating in mid‐air. The viewed image is spatially blended face images, where the spatial blending ratio depends on the viewing position. Thus, the aerial face image is perceived to look in a fixed orientation even if the viewing position is changed.
