IEEE VIS 2023 Best Paper Honorable Mention (x2) - VisuaLab & UNC Computer Science
August 31, 2023
A sensing network physicalization, both in the rendering stage and after fabrication
A sensing network physicalization (N = 20, L = 40). (a) A multi-material 3D printed network physicalization produced by Bae et al’s computational design pipeline. Conductive traces are embedded in the network’s links which enables node selection via capacitive sensing. (b) A computational rendering of the network physicalization showcasing how the conductive traces are distributed throughout the network’s links. The conductive traces use a serpentine pattern.

Members of UNC Computer Science’s VisuaLab received two Best Paper Honorable Mention awards from the 2023 IEEE Visualization Conference (VIS). The group also had a third paper accepted to the conference.

The VisuaLab, led by Assistant Professor Danielle Szafir, undertakes research at the intersection of data science, visual cognition, and computer graphics, examining how visualization design enhances understanding and engagement with data. It was founded while Szafir was a faculty member at the University of Colorado Boulder, and it includes personnel at both UNC-Chapel Hill and CU Boulder.

IEEE VIS papers recognized with an honorable mention award are those determined to be in the top 5 percent of all papers submitted to the conference in a given year. IEEE VIS is the top conference in the world for visualization research and one of the top conferences for computer graphics.

The first paper, “A Computational Design Pipeline to Fabricate Sensing Network Physicalizations,” was authored by Sandra Bae, a doctoral student advised by Szafir at CU Boulder. The paper introduced a design pipeline to 3D print physical representations of networks with embedded conductive traces enabling touch interactivity via capacitive sensing and computational inference.

The second paper, “CLAMS: A Cluster Ambiguity Measure for Estimating Perceptual Variability in Visual Clustering,” featured Ghulam Jilani Quadri as a co-first author. Quadri works as a CI Fellow Postdoctoral Research Associate with the VisuaLab at UNC-Chapel Hill. The paper deals with variability in the way that visual clustering is perceived and the difficulty in systematically assessing this ambiguity. The researchers developed CLAMS, a data-driven measure for predicting the cluster ambiguity of a visualization.
