Visual Link Routing in Immersive Visualisations

Abstract

Figure 1. Visual links can show associations between data points in coordinated visualisations. The routing of such links in immersive environments presents challenges such as considering the viewpoints of multiple users

Embodied gesture interaction for immersive maps

“…We also took inspiration from the interactive 2D flow map of U.S. migration by Stephen and Jenny (2017). Our immersive map (Figure 2) shows curved flow lines between counties and states using a modification of a constraint-based layout model developed by Prouzeau et al (2019). They designed their method to minimize visual clutter and occlusion by optimizing the routing of the three-dimensional flow lines.…”

“…However, similar "bringing together" interactions for creating visual links are applicable to other coordinated visualizations. For example,Prouzeau et al (2019) connect locations on immersive maps with associated statistical diagrams using visual links.…”

Personal Augmented Reality for Information Visualization on Large Interactive Displays

“…Cordeil et al [22] present a system to explore multidimensional data in Virtual Reality (VR) through manipulating and arranging linked axes. Approaches on how to ideally route links in immersive spaces have been analyzed by Prouzeau et al [69]. Alternatively, Liu et al [58] adapted the concept of small multiples to an immersive environment.…”

“…AR visualizations are directly situated on the display and analysts interact with proxies on the interactive surface. Furthermore, work that shows display-like surfaces in a pure VR environment [30,31,69] may be adapted to a setup consisting of a physical display and head-mounted AR.…”

“…To avoid this, we suggest displaying links on demand, e.g., showing them while an analyst touches a data mark, or displaying them only for a short amount of time to establish the necessary awareness. Alternatively, the links can be clustered or bundled [25,57,69] but this makes it difficult to follow individual links. In general, AR links can be used to augment data marks, links, and selections.…”
