    Physical Traces and Digital Stories: Exploring the Connections Between Forensics and Visualization
    (The Eurographics Association, 2022) Schetinger, Victor; Salisu, Saminu; Gillmann, Christina; Krone, Michael; Reina, Guido; Wischgoll, Thomas
    Forensics, or forensic science, deals with the analysis of evidence for investigation. It is a a wide and strongly interdisciplinary field that needs the coupling of research, practice, and communication to be useful. New techniques have to be constantly developed and applied in the field to solve social conflicts. Recent work suggests, however, that there are many gaps in this coupling, and we argue that there are lessons to be learned from them. Among the difficulties faced by forensics are the management of its interdisciplinarity and over-specialization, and the effective adoption of new research, which are also pressing for the visualization community. In this paper, we bring a gentle introduction to the challenges of forensics with a focus on its digital forms and explore connections to visualization. We believe these connections can be leveraged to further the development of both fields, and particularly that visualization and interaction are critical for the forensics process.

    Shapes of Time: Visualizing Set Changes Over Time in Cultural Heritage Collections
    (The Eurographics Association, 2019) Salisu, Saminu; Mayr, Eva; Filipov, Velitchko Andreev; Leite, Roger A.; Miksch, Silvia; Windhager, Florian; Madeiras Pereira, João and Raidou, Renata Georgia
    In cultural heritage collections, categorization is a central technique used to distinguish cultural movements, styles, or genres. For that end, objects are tagged with set-typed metadata and other information, such as time of origin. Visualizations can communicate how such sets organize a collection - and how they change over time. But existing interfaces fall short of a) representing an overview of temporal set-developments in an integrated fashion and b) of representing the set elements (i.e., the cultural objects) themselves to be contemplated on demand. Against this background, we introduce two integrated visualization techniques - a superimposition and a space-time cube view - depicting the development of sets and their elements over time. We share first results from a qualitative evaluation with casual users and outline open challenges for future research.

    Trust in Information Visualization
    (The Eurographics Association, 2019) Mayr, Eva; Hynek, Nicole; Salisu, Saminu; Windhager, Florian; Kosara, Robert and Lawonn, Kai and Linsen, Lars and Smit, Noeska
    Trust is an important factor that mediates whether a user will rely and build on the information displayed in a visualization. Research in other fields shows that there are different mechanisms of trust building: Users might elaborate the information deeply and gain a good understanding of the uncertainties in the data and quality of the information. But they might also use superficial cues as indicators for trust. Which processes are activated depends on the trustworthiness on the side of the visualization and on the trust perception by the users. We lay out challenges for future research to further improve our understanding of trust in information visualization.
