ATOM: Geometry-Aware Microgesture towards Object-Agnostic Tangible Interaction
Yinqiao Wang, Hao Xu, Qixuan Liu +3
This paper presents ATOM, an integrated framework towards agnostic and tangible object interactions with microgestures. Our goal is to support microgesture interactions across diff…
LiverPlan: A Stage-Adaptive Immersive Visual Analytics Framework for Anatomical Liver Surgical Planning
Qixuan Liu, Shi Qiu, Xiwen Wu +7
Anatomical liver resection (ALR) surgery is the most important treatment for liver cancer, yet preoperative planning demands complex, multi-stage clinical reasoning under competing…
CHOIR: Contact-aware 4D Hand-Object Interaction Reconstruction
Hao Xu, Yilin Liu, Yinqiao Wang +2
We ask whether everyday open-world monocular videos can be turned into reusable 4D interaction primitives: articulated hand motion, object shape with 6D pose over time, and the whe…
EgoHandICL: Egocentric 3D Hand Reconstruction with In-Context Learning
Binzhu Xie, Shi Qiu, Sicheng Zhang +5
Robust 3D hand reconstruction in egocentric vision is challenging due to depth ambiguity, self-occlusion, and complex hand-object interactions. Prior methods mitigate these issues…
A Collaborative Extended Reality Prototype for 3D Surgical Planning and Visualization
Shi Qiu, Ruiyang Li, Qixuan Liu +6
We present a collaborative extended reality (XR) prototype for 3D surgical planning and visualization. Our system consists of three key modules: XR-based immersive surgical plannin…
Coordinated 2D-3D Visualization of Volumetric Medical Data in XR with Multimodal Interactions
Qixuan Liu, Shi Qiu, Yinqiao Wang +4
Volumetric medical imaging technologies produce detailed 3D representations of anatomical structures. However, effective medical data visualization and exploration pose significant…
