| Research Abstract |
The goal of this research is to extract information about preparation or errors of movements from pre-movement or pre-stimulus brain activity, and to construct brain-computer interfaces that control external devices or support intended movements from brain activities of users. For this purpose, I conducted following three projects: measurement of brain activity using electroencephalogram (EEG) before movements, devolvement of classification algorithm for EEG data, and measurement of brain activity during movements using functional near-infrared spectroscopy (fNIRS). The results suggest that predicting occurrences of errors is possible from EEG data during pre-movement period, although further improvements are needed. Also, this research suggests feasibility of new algorithm using particle swam optimization and a possibility of combining fNIRS with EEG during movement tasks for improving an accuracy.
