Construction of virtual 3D life-like human hand for real-time human-computer interaction

Virtual hand plays an important role in many human-computer interaction applications. However, modeling a life-like 3D virtual hand is not a trivial task, especially the creation of flexible skin textures. In this paper, we propose a new method to execute texture mapping for the 3D virtual hand model automatically and apply it for human-computer interaction in real-time. Specifically, We first adjust the palm image using the mirror of the dorsal image. Then color transfer is performed for the palm image to ensure its similar color as the dorsal image. Finally interpolation is used to further adjust the direct texture mapping considering the virtual seams in fingers and thumb side. The proposed method is very efficient and experimental results show that the generated virtual hand model is more realistic than conventional virtual hands and can yield a stronger sense of immersion in the virtual world.
