Light-EmbodiedHAR: An Explainable IMU Sensor-Fusion Framework for Human Activity State Recognition in Assistive Robot Interaction

Human activity state recognition is a basic perception capability for assistive robots that interact with older adults, rehabilitation users, and workers in shared environments. However, many embodied-intelligence studies depend on vision-heavy perception pipelines that are difficult to deploy in low-cost, privacy-sens...

DiFF: Doppler-informed Flow Matching for Human Motion Flow

Perceiving human motion via privacy-preserving 4D millimeter-wave (mmWave) radar is critical for next-generation human-robot interaction (HRI), where point cloud scene flow serves as a foundational motion representation. Yet the extreme sparsity and noise of 4D radar point clouds make non-rigid motion flow estimation s...
