AiRound: a touchable mid-air image viewable from 360 degrees

Published: 28 November 2023 Publication History

Abstract

In this paper, we describe AiRound, an optical system that displays mid-air images that can be viewed from any direction. Mid-air images are touchable floating images formed by retroreflective transmissive optical elements that can seamlessly connect the virtual world to real space without special equipment. However, they are limited by three problems, including a limited range of observation, the visibility of the light source from the outside, and the aesthetically displeasing of stray light. The proposed system combines view control films and micromirror array plates to form a mid-air image that can be observed from 360 degrees by rotating these components at high speed.
