Floating display screen formed by AIRR (Aerial imaging by retro-reflection) for interaction in 3D space

This paper presents an interaction system with a floating display screen. Aerial imaging by retro-reflection (AIRR) forms an aerial LED screen that is floating over tabletop and is visible well over 120 degrees. In order to reduce latency, our system employs a high-frame-rate LED display and high-speed stereoscopic cameras. Developed system enables users to interact with aerially displayed information spontaneously.
