I mainly have research interests in visual tracking and posture estimation of human hand. A 3-D model based real-time estimation system has been developped and extended to very quick motion on complicated backgrounds and adaptation to personal body shape.

Also I am studying about personal robots with communication ability via oral and gestural interaction modes, which have abilities to interactively build common perceptions with humans and provide various information in both virtual and real worlds and physical services to disabled people.

I have additional interests on network security field, especially precise detection and protection of malformed communication and remote attacks

• Hand Tracking and 3-D Pose Estimation - A 2-D and 3-D model-based tracking method can track a human hand rapidly moving and deformed on complicated backgrounds and recover its 3-D pose parameters.
