[Paper] Absolute Parallax and Reconstruction Position of Aerial Image Formed Just Behind Viewing Eyes in Ultra-Wide Field-of-View Display

A novel display covering entire field of view with image is highly attractive for various application. This paper proposes to reconstruct an aerial image behind viewing eyes that are different from normal parallax of convergence side to realize ultra-wide field-of-view. As aerial display has no hardware around aerial image, we can observe aerial image formed behind the eyes between the display hardware and aerial image. We have developed a prototype aerial display to form an image just behind viewing eyes using aerial imaging by retro-reflection (AIRR). Even when aerial image is reconstructed behind viewing eyes, left and right reversed image with diverged absolute parallax to aerial image can be observed. Furthermore, our proposed method can cover entire field of view with images.
