Facial caricaturing should be discussed from multiple viewpoints of three relations among the model, the caricaturist and the gallery. Furthermore, some kinds of interactive mechanism should be required between the caricaturist and the gallery. In this paper, we propose a dynamic and interactive caricaturing system. In our system, the utilization of in betweening method realizes the generation mechanism from the caricaturist to the gallery, and on the contrary, the utilization of eye-camera vision realizes the feedback mechanism from the gallery to the caricaturist. The gallery mounts an eye-camera on the head, and the system reflects visual characteristics of the gallery directly onto the works of facial caricature. After observing the image of the model and analyzing the gaze direction and distribution, the system deforms some characteristic and impressive facial parts more strongly than other non-impressive facial parts, and generates the caricature, which is suited especially for the gallery. In this paper, we demonstrate experimentally the effectivity of this method to integrate these kinds of viewpoints.
