Abstract
Brain-Computer Interface (BCI), which provides a direct connection between the neural activity of human brain and machine, is being investigated in our study. In this paper, we examined the feasibility of using silent reading as a fundamental BCI trigger by measuring the real-time hemodynamic response during silent reading with Near Infrared Spectroscopy (NIRS). The results showed that hemodynamic response could be used as an ON/OFF switch during silent reading. This finding indicated that BCI control signals using Internal Speech Production can be put to practical use.
