Generation and Validation of 3D Links for Representative Hand Models

This paper proposes a method for constructing a three-dimensional (3D) link model of a representative hand model, and to change its posture. The link data were derived using bone mesh models extracted from MR (magnetic resonance) images of 18 subjects. The length of each link was estimated by stepwise multiple regression analysis of 98 hand measurements. A 3D link for the representative hand model was generated by deforming the generic hand model using the estimated link length. The proposed method was validated by constructing models for six actual subjects. Link lengths and the distances between salient points were compared.
