TactiCastVR: Exploring Lightweight Mediation for First Person Soccer Tactic Sensemaking
IEEE VIS 2026Under ReviewUt Gong*, Yingfangzhong Sun*, Run Zhu, Huishan Lai, Luyi Meng, Qihan Zhang, Zhijun Liang, Stefanie Zollmann
We present TactiCastVR, an immersive system informed by a formative study that uses lightweight, in-situ mediation (structural cues, event indicators, temporal traces, and optional viewpoint recommendations) to address breakdowns in global awareness and temporal continuity, and a 45-participant study shows it improves tactical understanding, especially for off-screen events and temporal-causal reasoning.

TimeFolder: A Universal Framework for Enhancing Visualization Across Time-Oriented Data Methods
CAD/CG 2026AcceptedTan Tang, Weichen Sun, Ut Gong, Shuhan Liu, Yang Liu, Yingcai Wu
TimeFolder applies the Minimum Description Length principle to compress long-term temporal data while preserving analytical fidelity. By balancing information density and visual saliency, it provides a universal interface for multi-scale time-series visualization.

In the Middle, Not on Top: AI-Mediated Communication for Patient–Provider Care Relationships
CHI 2026 WorkshopAcceptedUt Gong*, Yibo Meng*, Qihan Zhang, Xin Chen, Yan Guan
AI in clinical care should act as a mediator—not a decision-maker—supporting trust by redistributing interpretive work and reducing friction while preserving human judgment.

LGV-MKC: Large-Scale Graph Visualization through Mutual K-Core Identification
CHI 2026AcceptedYuting Chen, Ut Gong, Yiyang Yang, Zhiguo Gong
LGV-MKC introduces a scalable visualization framework for large networks based on mutual K-core decomposition, enabling clearer structural exploration and efficient visual summarization of dense graphs. The system integrates node aggregation, core membership encoding, and dynamic filtering for network insight discovery.

VAIR: Visual Analytics for Injury Risk Exploration in Sports
16th Workshop on Visual Analytics in Healthcare (VAHC) at IEEE VIS 2025AcceptedChunggi Lee, Ut Gong, Tica Lin, Hanspeter Pfister
VAIR integrates SMPL-based motion reconstruction with OpenSim-based risk modeling to visualize biomechanical loads across movement phases. The system maps injury risks using a structured Haddon Matrix and supports interactive exploration through 3D visualization and synchronized temporal plots.
