[Paper] Enhancement of Floating Sensation by Introducing Aerial Guide to Aerial Signage Formed with AIRR Using Fresnel Lens

Our goal is to realize a large-scale aerial display for the use of traffic information display. One of the primary challenges is to enhance the floating sensation of the aerial image. Depth perception diminishes with increasing distance due to inherent human visual limitations. Therefore, ingenuity was needed to make the aerial image appear to float over long distances. We propose the use of an aerial guide to enhance the observer's perception of the floating sensation in the aerial image at extended distance. The aerial guide is a frame that surrounds the aerial sign on the aerial image plane. The purpose of this paper is to confirm the effectiveness of aerial guide. We investigate how the presence of the aerial guide alters the observer's floating sensation using our prototype. Additionally, we examine the impact of varying colors on the floating effect of the aerial images through the method of pair comparison.
