||The human face is an independent communication channel that conveys emotional and conversational signals encoded as facial displays. We are attempting to introduce facial displays into multimodal human computer interaction as new modality to make computer morecommunicative and social. As a first step, we developed a multimodal humaan computer interaction as a new modality to make computer more communicative and social. The video gives an overview of the major research topics invovled in this project. They are to understand and manage speech dialogu, to design and animate communicative facial displays, and to combine multiple modalities, that is, speech and facial displays.
