To develop mid-air imaging optical systems, several simulation methods have been used by
tracking ray paths that generate a mid-air image as well as undesired images. Although …

In this paper, we propose a new approach to create a compact autostereoscopic aerial multi-
view display. It employs a transmission type retroreflector, ie a slit mirror array (SMA), and a …

With the mass-scale adoption of augmented reality (AR) in the commercial space, and
student interest in 3d-and 4d experiential learning, higher education is starting to look …

Mid-air images in a three-dimensional space beyond a screen enable users to observe
virtual content without wearing any devices. When using a symmetrical mirror structure with …

Many optical systems for displaying digital information on mirrors have been proposed, but
information can only be displayed in either mirrored or real space and cannot move back …

Although it is beneficial to use an optical simulator to design a mid-air imaging system, the
use of a simulator requires optical knowledge, and it cannot be handled by non-specialists …

Many methods have been proposed for presenting digital information in mirror space.
However, most existing methods can only display digital information in mirror space …

In this study, we propose PicPop, a pop-up picture book system that uses mid-air images to
make digital images pop out from a flat picture book. The user does not need to wear a …

A new optical system, called a “mirror‐transcending aerial imaging”, for freely displaying
digital information beyond the boundary between a mirrored space and a real space is …
