Development of a Wireless Embedded Brain - Computer Interface and Its Application on Drowsiness Detection and Warning

Conference paper
Part of the Lecture Notes in Computer Science book series (LNCS, volume 4562)


The existing bio-signal monitoring systems are mostly designed for signal recording without the capability of automatic analysis so that their applications are limited. The goal of this paper is to develop a real-time wireless embedded electroencephalogram (EEG) monitoring system that includes multi-channel physiological acquisition, wireless transmission, and an embedded system. The wireless transmission can overcome the inconvenience of wire routing and the embedded multi-task scheduling for the dual-core processing system is developed to realize the real-time processing. The whole system has been applied to detect the driver’s drowsiness for demonstration since drowsiness is considered as a serious cause of many traffic accidents. The electroencephalogram (EEG) features changes from wakefulness to drowsiness are extracted to detect the driver’s drowsiness and an on-line warning feedback module is applied to avoid disasters caused by fatigue.
