Abstract

We have developed a Brain Computer Interface (BCI) system to prevent car drivers actively from falling asleep. So far several technologies, such as imaging sensors to detect the face direction, behavior of the drivers, have been developed. They can not find the state of carelessness precisely by the imaging sensors. However, the brain wave, the amplitude of a late positive wave (P3 or P300) of the event-related brain potential (ERP), can indicate the amount of concentration of a user. By actively changing the source of audio stimuli, depending on the current ERP, our system keeps the user in the state of concentration and prevents the user from falling asleep. Thus, our system, auditory BCI system, monitors mental state of the drivers actively and warns them effectively.
