Certain diseases such as phantom pain or hemiplegia are caused by a mismatch between the real body and the own body model in brain. Mirror therapy is considered to improve these diseases and it can be considered as a process of eliminating the mismatch between the real body and the own body model. In this research, we focused on the changes in the perceived position of the finger. We performed an experiment with participants on four conditions and we designed four experimental conditions in which participants felt different sense of ownership and sense of agency. We investigated the relationship between the change in the perceived position and the sense of ownership and agency. We model the change according to the result, and furthermore, we showed that we can predict the future perceived position change with proposal model.
