Vortex ring based display

In this paper, we propose a new kind of mid-air projection display based on vortex ring. These days, there have been many studies and developments on mid-air displays that can display quite realistic floating holographic images in the real world. However, most of the conventional mid-air displays can only show their holographic images within a 2D plane and thus users can only enjoy very limited 3D sensation. Our proposed vortex ring display utilizes the great transportability of vortex ring to make a flying fog screen. We have found the proposed vortex ring display can break through the conventional limitation of 3D sensation and demonstrate more realistic physical effects together.
