    AI Agents and the Future of VIS

    Authors: Chen Zhu-Tian, Nam Wook Kim, Saeed Boorboor, Shivam Raval, Pan Hao, Qianwen Wang, Vidya Setlur

    Abstract: Recent advances in agents (i.e., autonomous, goal-driven AI systems that iteratively observe, act, and learn from their environments) offer a fundamentally different approach from traditional AI models that passively respond to input. These AI agents are rapidly reshaping how we approach data-intensive tasks and providing new opportunities for the VIS community. Imagine an agent autonomously gener… ▽ More

    Disrupting Cognitive Passivity: Rethinking AI-Assisted Data Literacy through Cognitive Alignment

    Authors: Yongsu Ahn, Nam Wook Kim, Benjamin Bach

    Abstract: AI chatbots are increasingly stepping into roles as collaborators or teachers in analyzing, visualizing, and reasoning through data and domain problem. Yet, AI's default assistant mode with its comprehensive and one-off responses may undermine opportunities for practitioners to develop literacy through their own thinking, inducing cognitive passivity. Drawing on evidence from empirical studies and… ▽ More

    From Answer Givers to Design Mentors: Guiding LLMs with the Cognitive Apprenticeship Model

    Authors: Yongsu Ahn, Lejun R Liao, Benjamin Bach, Nam Wook Kim

    Abstract: Design feedback helps practitioners improve their artifacts while also fostering reflection and design reasoning. Large Language Models (LLMs) such as ChatGPT can support design work, but often provide generic, one-off suggestions that limit reflective engagement. We investigate how to guide LLMs to act as design mentors by applying the Cognitive Apprenticeship Model, which emphasizes demonstratin… ▽ More

    "They Aren't Built For Me": An Exploratory Study of Strategies for Measurement of Graphical Primitives in Tactile Graphics

    Authors: Areen Khalaila, Lane Harrison, Nam Wook Kim, Dylan Cashman

    Abstract: Advancements in accessibility technologies such as low-cost swell form printers or refreshable tactile displays promise to allow blind or low-vision (BLV) people to analyze data by transforming visual representations directly to tactile representations. However, it is possible that design guidelines derived from experiments on the visual perception system may not be suited for the tactile percepti… ▽ More

    Understanding Why ChatGPT Outperforms Humans in Visualization Design Advice

    Authors: Yongsu Ahn, Nam Wook Kim

    Abstract: This paper investigates why recent generative AI models outperform humans in data visualization knowledge tasks. Through systematic comparative analysis of responses to visualization questions, we find that differences exist between two ChatGPT models and human outputs over rhetorical structure, knowledge breadth, and perceptual quality. Our findings reveal that ChatGPT-4, as a more advanced model… ▽ More

    Understanding Bias in Perceiving Dimensionality Reduction Projections

    Authors: Seoyoung Doh, Hyeon Jeon, Sungbok Shin, Ghulam Jilani Quadri, Nam Wook Kim, Jinwook Seo

    Abstract: Selecting the dimensionality reduction technique that faithfully represents the structure is essential for reliable visual communication and analytics. In reality, however, practitioners favor projections for other attractions, such as aesthetics and visual saliency, over the projection's structural faithfulness, a bias we define as visual interestingness. In this research, we conduct a user study… ▽ More

    Authors: Seongjun Choi, Youngbum Kim, Nam Woo Kim, Mansun Shin, Byunggi Chae, Sungjin Lee

    Abstract: In this paper, we propose the InfoFusion Controller, an advanced path planning algorithm that integrates both global and local planning strategies to enhance autonomous driving in complex urban environments. The global planner utilizes the informed Theta-Rapidly-exploring Random Tree Star (Informed-TRRT*) algorithm to generate an optimal reference path, while the local planner combines Model Predi… ▽ More

    Abstract: New tactile interfaces such as swell form printing or refreshable tactile displays promise to allow visually impaired people to analyze data. However, it is possible that design guidelines and familiar encodings derived from experiments on the visual perception system may not be optimal for the tactile perception system. We replicate the Cleveland and McGill study on graphical perception using swe… ▽ More

    ChatGPT in Data Visualization Education: A Student Perspective

    Authors: Nam Wook Kim, Hyung-Kwon Ko, Grace Myers, Benjamin Bach

    Abstract: Unlike traditional educational chatbots that rely on pre-programmed responses, large-language model-driven chatbots, such as ChatGPT, demonstrate remarkable versatility to serve as a dynamic resource for addressing student needs from understanding advanced concepts to solving complex problems. This work explores the impact of such technology on student learning in an interdisciplinary, project-ori… ▽ More

    DataGarden: Exploring our Community in a VR Data Visualization

    Authors: Joy Kondo, Justin Park, Josiah Kondo, Nam Wook Kim

    Abstract: As our society is becoming increasingly data-dependent, more and more people rely on charts and graphs to understand and communicate complex data. While such visualizations effectively reveal meaningful trends, they unavoidably aggregate data into points and bars that are overly simplified depictions of ourselves and our communities. We present DataGarden, a system that supports embodied interacti… ▽ More

    How Good is ChatGPT in Giving Advice on Your Visualization Design?

    Authors: Nam Wook Kim, Yongsu Ahn, Grace Myers, Benjamin Bach

    Abstract: Data visualization creators often lack formal training, resulting in a knowledge gap in design practice. Large language models such as ChatGPT, with their vast internet-scale training data, offer transformative potential to address this gap. In this study, we used both qualitative and quantitative methods to investigate how well ChatGPT can address visualization design questions. First, we quantit… ▽ More

    Understanding the Research-Practice Gap in Visualization Design Guidelines

    Authors: Nam Wook Kim, Grace Myers, Jinhan Choi, Yoonsuh Cho, Changhoon Oh, Yea-Seul Kim

    Abstract: Although empirical research often underpins practical visualization guidelines, it remains unclear how well these research-driven insights are reflected in the guidelines practitioners actually use. In this paper, we investigate the research-practice gap in visualization design guidelines through a mixed-methods approach. We collected 390 design guidelines from practitioner-facing sources and 235… ▽ More

    Kori: Interactive Synthesis of Text and Charts in Data Documents

    Authors: Shahid Latif, Zheng Zhou, Yoon Kim, Fabian Beck, Nam Wook Kim

    Abstract: Charts go hand in hand with text to communicate complex data and are widely adopted in news articles, online blogs, and academic papers. They provide graphical summaries of the data, while text explains the message and context. However, synthesizing information across text and charts is difficult; it requires readers to frequently shift their attention. We investigated ways to support the tight co… ▽ More

    TurkEyes: A Web-Based Toolbox for Crowdsourcing Attention Data

    Authors: Anelise Newman, Barry McNamara, Camilo Fosco, Yun Bin Zhang, Pat Sukhum, Matthew Tancik, Nam Wook Kim, Zoya Bylinskii

    Abstract: Eye movements provide insight into what parts of an image a viewer finds most salient, interesting, or relevant to the task at hand. Unfortunately, eye tracking data, a commonly-used proxy for attention, is cumbersome to collect. Here we explore an alternative: a comprehensive web-based toolbox for crowdsourcing visual attention. We draw from four main classes of attention-capturing methodologies… ▽ More

  18. Are all the frames equally important?

    Authors: Oleksii Sidorov, Marius Pedersen, Nam Wook Kim, Sumit Shekhar

    Abstract: In this work, we address the problem of measuring and predicting temporal video saliency - a metric which defines the importance of a video frame for human attention. Unlike the conventional spatial saliency which defines the location of the salient regions within a frame (as it is done for still images), temporal saliency considers importance of a frame as a whole and may not exist apart from con… ▽ More

    Abstract: Knowing where people look and click on visual designs can provide clues about how the designs are perceived, and where the most important or relevant content lies. The most important content of a visual design can be used for effective summarization or to facilitate retrieval from a database.
