A response model for a cg character based on timing of interactions in a multimodal human interface

In this paper, we propose a response model for a multimodal human interface, by inserting listener responses particular times by detecting keywords from the user’s utterances and controlling the face direction of a humanlike Computer Graphics (CG) character according to the direction of the user’s attention which is determined by tracing user’s face. Then we integrated the response model into a prototype system, and evaluated its efficiency
