These days, there have been many studies and developments on so-called mid-air displays that can display quite realistic virtual images in the real world without imposing any special apparatus on the users. However, most of the conventional mid-air displays limit their image effects to either the two dimentional display surfaces or the spaces inside of the displays. Therefore,there have been few research and development focused on pop-out image effects toward the user-side space. Furthermore, more people have paid greater attentions to research and development on five senses display, which can appeal to not only visual and audio senses but also olfactory and haptic sensesin recent days. Thus, we propose a new type of mid air display named vortexring display, which can not only compensate for the shortcoming of pop-outimage effects but also support five senses appealing multimodal image effects by taking advantage of the voretex's superior particle transport ability in order to make particle based projection screens made of light scattering particles,olfactory particles, heat particles, stimulus particles, etc. In this paper, we verify the visibility, continuity, viewing angles, and other basic problems throughour early experiments based on two prototypes that can project only fog based projection screen.
