Lucciola: Presenting Aerial Images by Generating a Fog Screenat any Point in the Same 3D Space as a User

Abstract

In this paper, we propose a method of presenting an aerial image at any point in the same three-dimensional space as a user. In the existing method, presenting an image to an arbitrary point in 3D space is difficult because the presentation position on the device is fixed. Therefore, in this study, particles with scattering properties remain to an arbitrary point in space and used as a screen. Specifically, we focus on the phenomenon of vortex rings that can stably transport particles, and we generate an aerial screen by colliding vortex rings ejected from air cannons at multiple points in the air. In a prototyping experiment, we generated a screen at a specified point in space and confirmed that aerial image presentation was possible by projection. We also determined potential issues.
