Abstract (en)
[origin: WO2007091199A2] A device and method for monitoring and/or assessing attention changes or lapses of a subject are described. The inventive device and method analyze the regularity of the period of a subject's cardiac cycle to detect a lapse or change of attention. When a subject is concentrating on a particular task or item the heart cycle exhibits strong regularity. But when attention to the task or item is interrupted or the subject's attention declines, the regular periodicity of the heart cycle declines. In a preferred implementation the heart cycle is detected by monitoring the subject's ECG waveform and performing cepstrum processing of the ECG data to determine a measure of R-wave regularity.
