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

TL;DR

This work introduces Proscenium, a dual-layer, large transparent display workspace setup with an adjustable separation between the layers, and demonstrates the preliminary design space focusing on how rendered information can be transitioned and linked across 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.

• Figure 1: Experiences that highlight non-verbal cues in telepresence, incl. emphasizing the stretch-out hand (a - c), critical object (d - e), and the internal states of the remote user (f - j).
• Figure 2: Experiences that demonstrate how the proximity afforded by the separation between layers can encourage the interactions, incl. pulling and pushing the shared app design for collaborative brainstorming (a - e), interacting with an embodied agent (f - j), highlighting the speaking user in multiparty videoconferencing (k - l), and opportunistic causal interactions (m - p).
• Figure 3: Experiences that provide management support of shared person and task spaces, incl. a seamless transition between shared person space and task space (a - c), overlays person and task space (d), and multiple task spaces (e).
• Figure 4: Experiences that demonstrate how the focused information at the front display can be linked at the back display, using strategies of none (a), halo (b), outline (c), and clone (d).
• Figure 5: Experiences that demonstrate (a) overview + detail and (b - d) the manifestation of physical proximity. Key entities extracted to the front display are highlighted by a purple circle.
