Aerial Display with Aerial Imaging by Retro-Reflection (AIRR)

Abstract

Aerial information display has been expected to handle information in real space. This paper introduces aerial imaging by retro-reflection (AIRR) and its applications for aerial LED signage and 3D interactive interfaces. AIRR forms an aerial screen that features an extremely wide viewing angle with a mass-productive retro-reflector. Because AIRR also features a large-size scalability, we have realized a life-scale aerial display by use of a 96-inch full-color LED panel. In order to enlarge viewing zones of the aerial LED screen, we have installed a transparent retro-reflector on an LED panel. Furthermore, in combination of the aerial display with the 3D gesture recognition camera, interactive interface systems have been realized. We can handle the aerial image directly in the mid-air.
