BCIを用いた随意的モータ制御における駆動閾値の比較検討

抄録

Recently, development of Brain-Computer Interface (BCI) which are enables non-contact operation of external devices by using electroencephalograms are progressing. This system is expected as an alternative communication tool for patients who are limited body function. However, BCI has expanded the area of research, it has problems such as high cost and instability due to requiring complicated control operation. On the other hand, evaluate the responsiveness and voluntariness of the system are also expected. Therefore, in this study participants conducted motor control tasks and clarified the voluntariness of the BCI based on the task success ratio. Also, "attention" acquired from the electroencephalogram sensor was used as the driving threshold of the motor, and 40, 50, 60, and 70 were set. As a result of comparing the task success ratio at each threshold value, when threshold is 60, the average is 50.8% and the result that the malfunction is small is obtained.
