摘　　要：The discovery of three-dimensional （3D） hand models corresponding to the user＇s 3D hand pose in initial frames is significant in 3D human hand tracking and interacting. This study proposes an approach to initial- ize 3D hand gestures for the user to have an easier, more pleasurable, and satisfactory experience. This paper cov- ers the following points. First, a new approach to selecting a human hand gesture from the hand postures database is presented. Second, both techniques of visualization and human-computer interaction are used in the initialization process, through which the 3D human hand model is fine- tuned time after time until the required accuracy is satis- fied. Lastly, the proposed initialization method is applied to our online virtual assembling system. We introduce a key factor to improve time cost of initialization. Our ex- perimental results show that the proposed approach is not only fast, accurate, and robust hut also direct, natural, and convenient for operators to handle.
