About

Chengjun Xu is a robotics and human-computer interaction researcher whose work centers on advancing intelligent human-robot collaboration through computer vision and machine learning. His research primarily addresses the challenge of enabling robots to perceive, interpret, and respond to human behavior in real-world, dynamic environments. Xu's most significant contributions lie in developing sophisticated pose estimation and action recognition systems for human-robot interaction. His 2023 paper on human-robot collaborative interaction, his most cited work with 20 citations, introduced a monocular multi-person 3D pose estimation method that allows robots to recognize human intentions and respond flexibly — a meaningful step toward more natural and intuitive robot behavior. Building on earlier foundations, his 2020 work on multi-view human pose estimation, garnering 14 citations, proposed an iterative approach for capturing 3D poses from multiple camera perspectives in real time. Xu has also explored multi-operator scenarios, developing context-aware systems that enable several humans to simultaneously interact with a single robot, and has investigated adaptive control strategies for physical human-robot collaboration using optimized admittance parameters. Collectively, his research makes a compelling case for integrating perceptual intelligence into collaborative robotics, with implications for manufacturing, assistive technology, and beyond.
