In this study, avatars in a virtual world are controlled using a dynamic physical model based on the musculoskeletal system. By managing the interaction between motion and sensory information, we can adjust sensations such as sensory attenuation and the sense of agency. We measure brain activity in real-time and use this data to develop a mathematical model that estimates subjective sensations. Furthermore, we aim to implement occupational therapy in a virtual environment and develop new treatment methods for schizophrenia.
