Aerial display with thermal and acoustic sensation

We have developed a visual, thermal and acoustic floating aerial display. Our developed display forms aerial visual images over a tabletop and locally heats a part of aerial images. Furthermore, our display forms locally aerial speaker on a part of aerial images, where sound pressure locally increases. Aerial images are formed with aerial imaging by retro-reflection (AIRR), which features a wide viewing angle, scalability, and mass-productivity. The aerial heater and the aerial speaker are realized with double-layered arrays of rectangular mirror (WARM) and crossed-mirror array (CMA), respectively. In combination of these imaging methods, we have realized a multi-modal aerial display.

Aerial light-field image augmented between you and your mirrored image

This paper proposes a method to form an aerial light-field image in front of a mirror. Our system consists of a specially fabricated punctured retro-reflector covered with a quarter-wave retarder and a reflective polarizer. The floating aerial 3D image is augmented between you and your mirrored image.

Brightness improvement by polarization modulation in the aerial imaging by retro-reflection (AIRR)

This paper reports reflective characteristics of a variety of retroreflectors. The dependence of reflectance on the incidence angle has been measured in detail. Polarization modulation increased brightness of the aerial image with the best retro-reflector.
