99. A Process for Deriving Heartrate Variability and its Comparison to Self-Reported Driver State
SessionPoster Session 2
DescriptionThis project focuses on the utilization of physiological heart rate variability (HRV) metrics derived from electrocardiograms (ECG). Furthermore, we also determined the best devices for data recording and developed an automated HRV processing pipeline. The HRV metrics were employed to monitor the recovery of driver vigilance resulting from an in-cabin karaoke feature. Engaging in the act of singing has been known to invigorate drivers and by providing it as a karaoke experience, the activity can be made engaging. A small study from 8 subjects showed a significant increase in self-reported alertness (p<0.01) and mood (p<0.01) after the karaoke activity. Karaoke activity resulted in a significant increase in HR (p<0.01). The HRV metric of low to high frequency power ratio (LF/HF) decreased significantly (p<0.01). Agreements between subjective alertness and mood with objective HR/HRV metrics indicate that karaoke is a good in-vehicle activity to recover driver vigilance.
