Exemplar figure, described by caption below — The user, a firefighter, has to save a victim. He uses a situated visualization: near the fire victim (the referent), stands a visualization of his vitals. However, a wall occludes the firefighter’s view from the referent. To perform his task, he uses a XR system that handles the non-visibility of the physical referent. This system shows an overlay on the wall showing a representation of the victim as well as the visualization.

Abstract

Situated visualizations are a type of visualization where data is presented next to its physical referent (i.e., the physical object, space, or person it refers to), often using augmented-reality displays. While situated visualizations can be benefcial in various contexts and have received research attention, they are typically designed with the assumption that the physical referent is visible. However, in practice, a physical referent may be obscured by another object, such as a wall, or may be outside the user’s visual feld. In this paper, we propose a conceptual framework and a design space to help researchers and user interface designers handle non-visible referents in situated visualizations. We frst provide an overview of techniques proposed in the past for dealing with non-visible objects in the areas of 3D user interfaces, 3D visualization, and mixed reality. From this overview, we derive a design space that applies to situated visualizations and employ it to examine various trade-offs, challenges, and opportunities for future research in this area.
