HiSync: Spatio-Temporally Aligning Hand Motion from Wearable IMU and On-Robot Camera for Command Source Identification in Long-Range HRI

Long-range Human-Robot Interaction (HRI) remains underexplored. Within it, Command Source Identification (CSI) – determining who issued a command – is especially challenging due to multi-user and distance-induced sensor ambiguity. We introduce HiSync, an optical-inertial fusion framework that treats hand motion as bin…

GazeCoT: Unleashing Social Intelligence in Multimodal LLMs With Gaze-Informed Chain-of-Thought Reasoning

Social intelligence is vital for effective human-AI interaction. While LLMs demonstrate strong text-based social intelligence, the vision modality remains challenging due to the presence of non-verbal social cues. For example, gaze is the primary conveyor of social attention, yet it cannot be accurately perceived and…

WritingRing: Enabling Natural Handwriting Input with a Single IMU Ring

Tracking continuous 2D sequential handwriting trajectories accurately using a single IMU ring is extremely challenging due to the significant displacement between the IMU's wearing position and the location of the tracked fingertip. We propose WritingRing, a system that uses a single IMU ring worn at the base of the f…
