In recent years, depth sensors, such as Kinect provides new opportunities for Human-Computer Interaction (HCI).
However, for more universalization of depth sensors in consumer electronics, the cost of the sensors should be
considered. In this paper, we proposed an algorithm for 3D hand localization by two commodity low cost webcams.
Because of the noise produced by the low cost webcams, the depth quality is not very good. Ac-cording to the poor
quality depth map, our algorithm can still to do the 3D hand localization. The proposed algorithm can provides 3D hand localization information for applications, such as interactive 3DTV.
