    A Design Study of Visualizing Historical Book Movement
    (The Eurographics Association, 2022) Xing, Yiwen; Dondi, Cristina; Borgo, Rita; Abdul-Rahman, Alfie; Agus, Marco; Aigner, Wolfgang; Hoellt, Thomas
    Trading of 15th-century books is an area of great interest to historians. In this paper, we document the process behind an intensive design study and close collaboration with a domain expert on understanding crucial historical research questions, together with the result of the design study - BookTracker, a tool for mining and visualizing circulation and movement of the 15th-century book trade. The main contribution includes a summary of insights from the design study and BookTracker, a web application supporting historians in: (i) query-based search of user-defined path sequences, and (ii) analysis of the movement of the resulting user-defined path sequences through multiple visualization techniques. We discuss and summarize the value and logistics of conducting this design study, which could become generalizable lessons for the visualization design methodology.

    Exploring Interpersonal Relationships in Historical Voting Records
    (The Eurographics Association and John Wiley & Sons Ltd., 2023) Cantareira, Gabriel Dias; Xing, Yiwen; Cole, Nicholas; Borgo, Rita; Abdul-Rahman, Alfie; Bujack, Roxana; Archambault, Daniel; Schreck, Tobias
    Historical records from democratic processes and negotiation of constitutional texts are a complex type of data to navigate due to the many different elements that are constantly interacting with one another: people, timelines, different proposed documents, changes to such documents, and voting to approve or reject those changes. In particular, voting records can offer various insights about relationships between people of note in that historical context, such as alliances that can form and dissolve over time and people with unusual behavior. In this paper, we present a toolset developed to aid users in exploring relationships in voting records from a particular domain of constitutional conventions. The toolset consists of two elements: a dataset visualizer, which shows the entire timeline of a convention and allows users to investigate relationships at different moments in time via dimensionality reduction, and a person visualizer, which shows details of a given person's activity in that convention to aid in understanding the behavior observed in the dataset visualizer. We discuss our design choices and how each tool in those elements works towards our goals, and how they were perceived in an evaluation conducted with domain experts.

    Simple Techniques for a Novel Human Body Pose Optimisation Using Differentiable Inverse Rendering
    (The Eurographics Association, 2022) Battogtokh, Munkhtulga; Borgo, Rita; Pelechano, Nuria; Vanderhaeghe, David
    Human body 3D reconstruction has a wide range of applications including 3D-printing, art, games, and even technical sport analysis. This is a challenging problem due to 2D ambiguity, diversity of human poses, and costs in obtaining multiple views. We propose a novel optimisation scheme that bypasses the prior bias bottleneck and the 2D-pose annotation bottleneck that we identify in single-view reconstruction, and move towards low-resource photo-realistic 3D reconstruction that directly and fully utilises the target image. Our scheme combines domain-specific method SMPLify-X and domain-agnostic inverse rendering method redner, with two simple yet powerful techniques. We demonstrate that our techniques can 1) improve the accuracy of the reconstructed body both qualitatively and quantitatively for challenging inputs, and 2) control optimisation to a selected part only. Our ideas promise extension to more difficult problems and domains even beyond human body reconstruction.

    A Survey of Human-Centered Evaluations in Human-Centered Machine Learning
    (The Eurographics Association and John Wiley & Sons Ltd., 2021) Sperrle, Fabian; El-Assady, Mennatallah; Guo, Grace; Borgo, Rita; Chau, Duen Horng; Endert, Alex; Keim, Daniel; Smit, Noeska and Vrotsou, Katerina and Wang, Bei
    Visual analytics systems integrate interactive visualizations and machine learning to enable expert users to solve complex analysis tasks. Applications combine techniques from various fields of research and are consequently not trivial to evaluate. The result is a lack of structure and comparability between evaluations. In this survey, we provide a comprehensive overview of evaluations in the field of human-centered machine learning. We particularly focus on human-related factors that influence trust, interpretability, and explainability. We analyze the evaluations presented in papers from top conferences and journals in information visualization and human-computer interaction to provide a systematic review of their setup and findings. From this survey, we distill design dimensions for structured evaluations, identify evaluation gaps, and derive future research opportunities.

    Unveiling the Dispersal of Historical Books from Religious Orders
    (The Eurographics Association, 2023) Xing, Yiwen; Yan, Dengyi; Dondi, Cristina; Borgo, Rita; Abdul-Rahman, Alfie; Gillmann, Christina; Krone, Michael; Lenti, Simone
    In this paper, we introduce a visualization prototype designed to assist historians in exploring the dispersal of books from religious orders throughout Europe during the sixteenth century and beyond. The prototype is the result of a collaboration between visualization researchers and a historical book researcher, aiming to apply visualization techniques to address realworld domain challenges. Over two months, we engaged in an intensive collaboration with the domain expert to analyze domain issues and requirements and subsequently developed a prototype featuring two interfaces. Weekly discussions with the domain expert guided design and ongoing prototype evaluation. In its infancy, the prototype shows promise for enhancement and scalability. Future efforts will target systematic usability and practicality evaluations.
