Abstract
Occupational drivers require long term sustained attention to be able to act vigilantly to stimuli in their environment. Due to the long hours that they work, fatigue has a great impact on the level of vigilance they can portray at any given moment. In previous research, it has been found that fatigue can be predicted through measures of heart rate variability, namely an increase of LF (0.04-0.15Hz) contribution in a heart rate frequency analysis (Chua et al., 2012). In the current study, we aimed to determine the validity of the Empatica E4 and Polar H10 to see if they could be used as alternatives to gold standard heart rate measuring devices, such as the TMSI REFA amplifier. This has been done by comparing the IBI’s collected from participants (N=28), by the two devices, to the TMSI REFA amplifier, while the participants undergo a psychomotor vigilance task. We found that the Polar H10 was highly correlated with the TMSI REFA amplifier (r=.993, p<.001), with 97.4% of the IBI’s being in a ±0.002sec of the TMSI REFA amplifier. This suggested that the Polar H10 would be valid enough to predict attentional failure. However, the Empatica E4 suffered from motion artefacts, leading to 81.2% of the IBI’s not being registered. This suggested that the Empatica E4 was not sufficiently valid to predict attentional failure in occupational drivers. Limitations of the study include that HRV frequency analysis has not been compared for the devices, as the paper assumes that the IBI’s have to be precise to determine valid results for the LF component of the HRV frequency analysis.
