Conversational AI Media Design Portfolio


Yoichi Matsuyama (松山 洋一) is a Post Doctoral Fellow (Special Faculty) at the ArticuLab in the School of Computer Science, Carnegie Mellon University. He has been designing and developing a number of conversational AI media systems for more than a decade. His research interest lies in computational models of human conversations, which combine artificial intelligence, social science and human-computer/robot interaction design. In the ArticuLab, he is leading SARA (Socially Aware Robot Assistant) project that was exhibited in a number of high profile conferences, such as the World Economic Forum Annual Meeting 2017, Davos, Switzerland. SARA was featured in numerous major media, such as MIT Technology Review, Washington Post, CNBC, BBC, CNET, Popular Science and Science Friday. His Ph.D dissertation project was SCHEMA, a multiparty conversation facilitation robot, specifically its computational models of facilitation strategies and language generation, as well as its robotic platform development. Prior to CMU, he was a researcher at the Perceptual Computing Group, Waseda University in Tokyo. He was also a visiting scholar in the iCub Facility (an embodied cognitive robotics research group), Italian Institute of Technology, and a committee member of ACM SIGGRAPH Asia. He received B.A. in cognitive psychology and media studies, M.E. and Ph.D in computer science from Waseda University in 2005, 2008 and 2015 respectively.

“Speaking with SARA certainly felt less jarring than talking to a regular chatbot. The system studies the words a person says during a conversation as well as the tone of his or her voice, also using several cameras to study the speaker’s facial expressions and head movements.”
