Breaking the Fourth Wall of data Stories through Interaction

IEEE Transactions on visualization and Computer Graphics 2023年第1期29卷 972-982页

作者： Shi, Yang Gao, Tian Jiao, Xiaohan Cao, Nan Tongji University Intelligent Big Data Visualization Lab China

Interaction is increasingly integrating into data stories to support data exploration and explanation. Interaction can also be combined with the narrative device, breaking the fourth wall (BTFW), to build a deeper connection between readers and data stories. BTFW interaction directly addresses readers by requiring their input. Such user input is then integrated into the narrative or visuals of data stories to encourage readers to inspect the stories more closely. In this work, we explore the design patterns of BTFW interaction commonly used in data stories. Six design patterns were identified through the analysis of 58 high-quality data stories collected from a range of online sources. Specifically, the data stories were categorized using a coding framework, including the input of BTFW interaction provided by readers and the output of BTFW interaction generated by data stories to respond to the input. To explore the benefits as well as concerns of using BTFW interaction, we conducted a three-session user study including the reading, interview, and recall sessions. The results of our user study suggested that BTFW interaction has a positive impact on self-story connection, user engagement, and information recall. We also discussed design implications to address the possible negative effects on the interactivity-comprehensibility balance, information privacy, and the learning curve of interaction brought by BTFW interaction. © 2022 IEEE.

Supporting Expressive and Faithful Pictorial visualization Design with Visual Style Transfer

引用

IEEE Transactions on visualization and Computer Graphics 2023年第1期29卷 236-246页

作者： Shi, Yang Liu, Pei Chen, Siji Sun, Mengdi Cao, Nan Tongji University Intelligent Big Data Visualization Lab China

Pictorial visualizations portray data with figurative messages and approximate the audience to the visualization. Previous research on pictorial visualizations has developed authoring tools or generation systems, but their methods are restricted to specific visualization types and templates. Instead, we propose to augment pictorial visualization authoring with visual style transfer, enabling a more extensible approach to visualization design. To explore this, our work presents Vistylist, a design support tool that disentangles the visual style of a source pictorial visualization from its content and transfers the visual style to one or more intended pictorial visualizations. We evaluated Vistylist through a survey of example pictorial visualizations, a controlled user study, and a series of expert interviews. The results of our evaluation indicated that Vistylist is useful for creating expressive and faithful pictorial visualizations. © 2022 IEEE.

Understanding Design Collaboration Between Designers and Artificial Intelligence: A Systematic Literature Review

引用

Proceedings of the ACM on Human-Computer Interaction 2023年第CSCW2期7卷 1-35页

作者： Shi, Yang Gao, Tian Jiao, Xiaohan Cao, Nan Intelligent Big Data Visualization Lab Tongji University Shanghai China

Recent interest in design through the artificial intelligence (AI) lens is rapidly increasing. Designers, as a special user group interacting with AI, have received more attention in the Human-Computer Interaction community. Prior work has discussed emerging challenges that persist in designing for AI. However, few systematic reviews focus on AI for design to understand how designers and AI can augment each other's complementary strengths in design collaboration. In this work, we conducted a landscape analysis of AI for design, via a systematic literature review of 93 papers. The analysis first provides a bird's eye view of overall patterns in this area. The analysis also reveals three themes interpreted from the paper corpus associated with AI for design, including AI assisting designers, designers assisting AI, and characterizing designer-AI collaboration. We discuss the implications of our findings and suggested methodological proposals to guide HCI toward research and practices that center on collaborative creativity. © 2023 ACM.

As an effective form of narrative visualization, visual data stories are widely used in data-driven storytelling to communicate complex insights and support data understanding. Although important, they are difficult to create, as a variety of interdisciplinary skills, such as data analysis and design, are required. In this work, we introduce Erato, a human-machine cooperative data story editing system, which allows users to generate insightful and fluent data stories together with the computer. Specifically, Erato only requires a number of keyframes provided by the user to briefly describe the topic and structure of a data story. Meanwhile, our system leverages a novel interpolation algorithm to help users insert intermediate frames between the keyframes to smooth the transition. We evaluated the effectiveness and usefulness of the Erato system via a series of evaluations including a Turing test, a controlled user study, a performance validation, and interviews with three expert users. The evaluation results showed that the proposed interpolation technique was able to generate coherent story content and help users create data stories more efficiently. © 2022 IEEE.

To solve the 2024 VAST Challenge MC3, we use PageRank and different filtering techniques to select nodes or components of interest. We then use TimeArc, a data visualization technique to visualize the evolution of the corporate structure of these nodes and serve as a tool to investigate and confirm this suspicious behavior. We used these techniques to investigate many nodes including the given SouthSeafood Express Corp that was involved in illegal activity. We discovered a few key features associated with anomalous nodes such as instances of founding shell companies and large power transfers. © 2024 IEEE.

Proceedings of the ACM on Human-Computer Interaction 2022年第CSCW2期6卷 1-25页

作者： Shi, Yang Chen, Siji Liu, Pei Long, Jiang Cao, Nan Intelligent Big Data Visualization Lab Tongji University Shanghai China Huawei Technologies Co. Ltd. Hangzhou China

visualization dashboards serve as an information presentation that uses a tiled layout of key metrics visualized in charts for collaborative decision-making. Existing work has developed tools and techniques for computational color design. Much of these efforts have focused on selecting effective color palettes for independent charts while few attempts have been made to support the expressive color design of multiple coordinated charts in dashboards. In this work, we describe ColorCook, an interactive system that helps design expressive and effective dashboard colorings using domain-Associated palettes. ColorCook employs an integrated color workflow for dashboarding, consisting of color selection, assignment, and adjustment. We evaluated ColorCook through a crowdsourcing experiment and a user study. The results of our evaluation indicated that ColorCook is useful for effective and expressive color design. © 2022 ACM.

How Does Emotion Affect Information Communication

arXiv

引用

arXiv 2025年

作者： Cao, Shixiong Cao, Nan Intelligent Big Data Visualization Lab Tongji University China

In recent years, the pivotal role of emotions in information dissemination has attracted extensive attention. Research indicates that emotionally charged content significantly outperforms neutral content in dissemination speed and coverage due to its ability to evoke stronger emotional responses. Valence, arousal, and dominance are key factors influencing information retention, comprehension, and sharing. However, systematic analysis of the mechanisms by which emotions affect dissemination and the application of multidimensional emotional design remain limited. This study reviews 166 relevant articles, examining the role of emotions in understanding and sharing information, and proposes a multidimensional design framework based on text, visuals, sound, and interaction design. Incorporating the "Four-System" model of emotion activation, it develops an emotion regulation framework to optimize the application of emotions in dissemination. This research offers theoretical support and practical guidance for emotion-driven dissemination, laying a foundation for advancing this field. Copyright © 2025, The Authors. All rights reserved.

FreeShell: A Context-Free 4D Printing Technique for Fabricating Complex 3D Triangle Mesh Shells

arXiv

arXiv 2024年

作者： Yuan, Chao Cao, Nan Ma, Xuejiao Dang, Shengqi Intelligent Big Data Visualization Lab Tongji University China

Freeform thin-shell surfaces are critical in various fields, but their fabrication is complex and costly. Traditional methods are wasteful and require custom molds, while 3D printing needs extensive support structures and post-processing. Thermoshrinkage actuated 4D printing is an effective method through flat structures fabricating 3D shell. However, existing research faces issues related to precise deformation and limited robustness. Addressing these issues is challenging due to three key factors: (1) Difficulty in finding a universal method to control deformation across different materials;(2) Variability in deformation influenced by factors such as printing speed, layer thickness, and heating temperature;(3) Environmental factors affecting the deformation process. To overcome these challenges, we introduce FreeShell, a robust 4D printing technique that uses thermoshrinkage to create precise 3D shells. This method prints triangular tiles connected by shrinkable connectors from a single material. Upon heating, the connectors shrink, moving the tiles to form the desired 3D shape, simplifying fabrication and reducing material and environment dependency. An optimized algorithm for flattening 3D meshes ensures precision in printing. FreeShell demonstrates its effectiveness through various examples and experiments, showcasing accuracy, robustness, and strength, representing advancement in fabricating complex freeform surfaces. © 2024, CC BY-NC-SA.
