It is a common sense that drowsiness during driving could cause traffic accidents. Related researches show that drowsiness occurs when the parasympathetic nerve system predominates over others, and the high frequency (HF) component of heart rate variability (HRV) on an electrocardiogram (ECG) is closely related with the parasympathetic nerve activity, so it is reasonable to evaluate drowsiness based...
General Systems Performance Theory (GSPT) was initially motivated by problems associated with quantifying different aspects of human performance. It has proved to be invaluable for measurement development and understanding quantitative relationships between human subsystem capacities and performance in complex tasks. It is now desired to bring focus to the application of GSPT to modeling of cognitive...
Electroencephalogram (EEG) based vigilance detection of those people who engage in long time attention demanding tasks such as monotonous monitoring or driving is a key field in the research of brain-computer interface (BCI). However, robust detection of human vigilance from EEG is very difficult due to the low SNR nature of EEG signals. Recently, compressive sensing and sparse representation become...
This paper describes the development of a laboratory experiment related with drowsiness in order to find patterns in biomedical signals that allow to distinguish the periods of drowsiness, contrasted with sleep phases obtained by EEG analysis and current methods used to detect the fall of attention in drivers.
Employing the analysis of a biomarker, an oculomotor angle and a subjective evaluation, we have examined the acute, psychological effect human stress of driving using a motor-vehicle driving simulator. Salivary amylase is used as a biomarker, as it is considered to be one of the indicators of sympathetic nervous activity. 20 healthy female subjects in their early twenties were enrolled in this study...

To date, no study has tested the reproducibility of EEG changes that occur during driver fatigue. For the EEG changes to be useful in the development of a fatigue countermeasure device the EEG response during each onset period of fatigue in individuals needs to be reproducible. It should be noted that fatigue during driving is not a continuous process but consists of successive episodes of ‘microsleeps’...
