Toward a sustainable ecosystem for aerial displays: a triple-track approach integrating research, deployment, and standardization

Aerial displays, which form real images in mid-air using passive optical elements, are gaining attention for contactless interaction and spatial computing. However, widespread adoption requires not only technological advancement but also international standardization and real-world implementation. This paper introduces a triple-track approach integrating academic research, social implementation, and standardization. On the standardization front, key contributions include the publication of IEC TR 62629-51-1 and IS 62629-52-1, defining optical measurement methods for aerial displays. On the implementation side, examples range from floating LED signage to applications in entertainment and public exhibitions, including modern Noh theater and television drama. These efforts culminated in a national showcase of future technologies in 2025, where aerial displays were highlighted as a bridge between real and digital spaces. The presentation outlines a roadmap toward sustainable ecosystem development for aerial displays based on research-driven innovation and standardization-supported trust.
