Proscenium: Exploring Design Spaces of Layered Information Experience on a Large Dual-Layer Transparent Display

2026-03-01

AI Summary

This study addresses the lack of systematic guidance in layered information interaction design for dual-layer transparent displays. To this end, the authors present Proscenium, a large-scale dual-layer transparent display workstation with adjustable inter-layer spacing, integrating layered rendering and information linkage techniques. Building upon this platform, they propose the first design space specifically tailored for layered information experiences on such devices. The work further demonstrates the feasibility and diversity of layered information presentation through 14 forward-looking interactive prototypes spanning six application scenarios. These contributions establish both a theoretical framework and a practical foundation for future interface design on transparent displays.

Abstract

Layering information spaces is a promising strategy to design intuitive and engaging interactive experiences. Although multi-layer displays enable promising interaction techniques through limited depth perception - achieved via slight separation between layers - it remains unclear how to fully design experiences that leverage the unique affordances of layered information. To address this, we introduce Proscenium, a dual-layer, large transparent display workspace setup with an adjustable separation between the layers. We demonstrate our preliminary design space focusing on how rendered information can be transitioned and linked across displays, and showcase 14 speculative experience prototypes across six categories.
