Multi-speaker Attention Alignment for Multimodal Social Interaction

Liangyang Ouyang, Yifei Huang, Mingfang Zhang +3

Understanding social interaction in video requires reasoning over a dynamic interplay of verbal and non-verbal cues: who is speaking, to whom, and with what gaze or gestures. While…

Affordance-Guided Diffusion Prior for 3D Hand Reconstruction

Naru Suzuki, Takehiko Ohkawa, Tatsuro Banno +3

How can we reconstruct 3D hand poses when large portions of the hand are heavily occluded by itself or by objects? Humans often resolve such ambiguities by leveraging contextual kn…

AssemblyHands-X: Modeling 3D Hand-Body Coordination for Understanding Bimanual Human Activities

Tatsuro Banno, Takehiko Ohkawa, Ruicong Liu +2

Bimanual human activities inherently involve coordinated movements of both hands and body. However, the impact of this coordination in activity understanding has not been systemati…

Generative Modeling of Shape-Dependent Self-Contact Human Poses

Takehiko Ohkawa, Jihyun Lee, Shunsuke Saito +7

One can hardly model self-contact of human poses without considering underlying body shapes. For example, the pose of rubbing a belly for a person with a low BMI leads to penetrati…

EgoInstruct: An Egocentric Video Dataset of Face-to-face Instructional Interactions with Multi-modal LLM Benchmarking

Yuki Sakai, Ryosuke Furuta, Juichun Yen +1

Analyzing instructional interactions between an instructor and a learner who are co-present in the same physical space is a critical problem for educational support and skill trans…

EgoBrain: Synergizing Minds and Eyes For Human Action Understanding

Nie Lin, Yansen Wang, Dongqi Han +5

The integration of brain-computer interfaces (BCIs), in particular electroencephalography (EEG), with artificial intelligence (AI) has shown tremendous promise in decoding human co…

Leadership Assessment in Pediatric Intensive Care Unit Team Training

Liangyang Ouyang, Yuki Sakai, Ryosuke Furuta +3

This paper addresses the task of assessing PICU team's leadership skills by developing an automated analysis framework based on egocentric vision. We identify key behavioral cues,…

SiMHand: Mining Similar Hands for Large-Scale 3D Hand Pose Pre-training

Nie Lin, Takehiko Ohkawa, Yifei Huang +5

We present a framework for pre-training of 3D hand pose estimation from in-the-wild hand images sharing with similar hand characteristics, dubbed SimHand. Pre-training with large-s…
