According to the advanced aging society, talking care of the person whose physical functions are declared has become more important issue. Many types of assist devices are developed to keep their Q.O.L. in their independent day-life. It is important to reflect user's intention to the device and we focused on a brain wave which is expected as a means of communication of user's intention. An EEG is used among the brain waves and we aimed at using it to apply for a brain machine interface (BMI) system. In this study, we measured an EEG during a hand/foot motion and developed an ON/OFF control of the mechanical device based on the brain concentration.
