| Abstract(in English) | Electroencephalogram (EEG) is a way to inspect medical diagnoses such as epilepsy and then there is a further potential to apply other medical treatment by coupling with advanced signal analysis methods. In this study, we focused on a possibility for evaluating the status of the motor rehabilitation and investigate the effect by using a simultaneous measurement system with the EEG, eye-tracker capturing gaze movements and motion capture system. In the grasping task to discriminate types of posture as cylindrical, lumbrical and pinch, ERD/ERS analyses were examined with seven subjects. ERD/ERS analyses clearly demonstrated the statistical difference to discriminate cylindrical, lumbrical and pinching grasping postures in cases of combinations of chosen few subjects, while the statistical difference is getting to be unclear in cases of more than five subjects, which averaged against inter-subject variances. For a generalization of the scheme, individual differences on motion initiation timing can be considered, while a simplification by changing the spatial resolution of the ERD/ERS analysis may work well for the improvement of the classification performance. |
