Research Summary

We conduct research to elucidate the computational mechanisms of human mind (emotions, cognition, and behavior) to develop robots with mind.
Specifically, we conduct the following research.
- Computational elucidation of human mind; its implementation in robots collaborating with engineers.
- Psychological evaluation of robots' functions.
- Interdisciplinary research across psychology, informatics, and robotics, especially on emotional communication.
