Hand posture estimation using 3D range data for an evaluation system of human hand manipulation

This paper describes an approach to estimate human hand posture using 3-dimensional range data. The approach employs an approximation of the human hand with a plane in the 3-dimensional space. While this approximation is not so precise for detail reconstruction of the hand shape, it is intended for tracking of the human hand in applications such as virtual reality applications, in which relatively low precision is acceptable.
