Automatic design of a control interface for a synthetic face
Getting synthetic faces to display natural facial expressions is essential to enhance the interaction between human users and virtual characters. Yet traditional facial control techniques provide precise but complex sets of control parameters, which are not adapted for non-expert users. In this article, we present a system that generates a simple, 2Dimensional interface that offers an efficient control over the facial expressions of any synthetic character. The interface generation process relies on the analysis of the deformation of a real human face. The principal geometrical and textural variation patterns of the real face are detected and automatically reorganized onto a low-dimensional space. This control space can then be easily adapted to pilot the deformations of synthetic faces. The resulting virtual character control interface makes it easy to produce varied emotional facial expressions, both extreme and subtle. In addition, the continuous nature of the interface allows the...
