Abstract(in English) Our research group has been studying a speech communication system with a virtual agent (VA), to support person-centered care (PCC) of people with dementia (PWD). The current system uses the 3D model based on an unreal character for the VA. Because the unfamiliar appearance is to be a mental obstacle to PWD, PWD hardly accept advice and, which causes a limitation in the care effects. In this paper, we develop a novel system that dynamically creates a VA based on a given facial image of real person. The proposed system constructs a three-dimensional model based on facial landmarks within the image. It then stretches and transforms some portions of the 3D model to generate facial expressions. From just a given picture, the proposed system easily generates a communication agent familiar with individual PWD. Hence, it can provide effective care through conversations with familiar VA.
