      Raquel Bail\u00f3n, researcher at the BSICOS group, was at the\u00a0R + D + i Conference for the Mobility of the Future.<\/strong>\u00a0There, she presented her work on \u201cDetection of stress and drowsiness in the driver through the processing of physiological signals\u201d.<\/p>\n

      Between\u00a020-30% of traffic accidents are due to drowsiness, fatigue or stress,<\/strong>\u00a0which are closely related to the activity of the autonomic nervous system (ANS). The activity of the ANS can be monitored non-invasively by processing\u00a0biomedical signals<\/strong>, in particular, of the heart rate variability (HRV) obtained from the electrocardiographic (ECG) signal or the photoplethysmographic signal of pulse (PPG).<\/p>\n

      HRV monitoring has the potential to identify states of drowsiness, fatigue and stress, of great importance for\u00a0accident prevention<\/strong>. A drowsiness episode detector has been developed that identifies the current state of the person, alerting the driver when they are drowsy or fatigued at the wheel. In addition, a sleep deprivation detector has been developed, which identifies the global state of the person at the beginning of driving, indicating whether or not they are suitable for it. It is emphasized that for a better performance and interpretation of HRV it is necessary to\u00a0incorporate respiratory information<\/strong>\u00a0and reduce the effect of movement artifacts.<\/p>\n
