Human hand modeling, analysis and animation in the context of HCI
The use of human hand as a natural interface device serves as a motivating force for research in visual analysis of highly articulated hand movement. Since hand motion covers a huge domain, the scope of this paper is limited to the developments of 3D model-based approaches. Numerous 3D models that have been used to analyze hand motion are studied. Various approaches to articulated motion analysis are discussed. Some realistic synthesis methods are also included in this paper. We conclude with some thoughts about future research directions.
