小型 NIRS-BCI を対象とした脳活動の識別方法の検討

抄録

Brain Computer Interface (BCI) is a system that controls machines and devices by extracting neural information from human brain activity and it is expected for nursing robot such as an artificial hand. Near Infrared Spectroscopy (NIRS) is a measurement method using near infrared light for detecting brain activity. However, NIRS signal has noise and trend which disturbs detection of brain activity. In this study, we propose a signal processing method for improving detection accuracy and carried out the detection experiment to compare previous method and proposed method. The experimental results show that the proposed method is effective for NIRS-BCI system.
