We (Seiji Yamada Lab) are studying AI systems and AI agents that can effectively cooperate with humans by using AI and HCI techniques like machine learning and interaction design. We consists of doctoral candidates in a department of informatics in Sokendai (Graduate University of Advanced Studies) and other universities, visiting researchers. The followings are our current main research topics.

  • HAI (human-agent interaction): A research field in which we study various interaction design between a human and a virtual agent, a human and a physical robot, and a human and a human through mediation agents. The final target is to develop a fundamental and common interaction design policy which can be applied to the three different interactions. AI, soft computing, machine learning, cognitive science, robotics, are closely related to HAI. The concrete research target is to investigate relationships between various properties of virtual agents and a human by conducting experiments with participants. Our research projects on HAI are described the HAI projects page.
  • IIS (Intelligent Interactive Systems): A study field in which we study how to build intelligent interactive systems that can estimate a user’s internal states including his/her degree of understanding a task, systems’ strategies, and also the user easily can understand how the systems can learn and adapt to them. Only with such intelligent interactive systems, a human user is able to do creative cooperation tasks with machines like computers. Particularly, interactive machine learning, very efficient learning with valid accuracy, interaction design for retrieve human ability including human active learning. Our research projects on IIS are described the IIS projects page.
  • TID (Trust Interaction Design): Our new research theme is on various methods to design interaction for trustworthy AI. We focus on trust calibration, prediction of trust dynamics, and over/under-trust prevention. This research is progressing based on a JST CREST project from Oct. 2021 to Mar. 2027.
