Use of physiological responses, captured by consumer grade electronics, for objective evaluation of drivers’ state
This session aims to demonstrate the use of human physiological responses, captured by consumer grade electronic devices, for objective evaluation of drivers’ state, or as it commonly referred to, Driver State Monitoring (DSM). Despite the novelty of this research area, it was forecasted that a DSM system might become a standard passenger car feature by 2025. Such system will equip future vehicles with ability to estimate driver state constructs such as distraction, workload, and fatigue. This could help to minimise human error occurrences on roads by keeping those constructs at optimal threshold. Therefore, the numerous attempts, both in academia and industry, were made to objectify driver state by linking it to physiological indicators including, heart rate and skin sweatiness; these can be measured using various sensors and wearable devices attached to human body or embedded into a vehicle. This talk, however, specifically focuses on the use of consumer grade sensors and wearables including, devices such as, smartwatches and fitness bands. The data from two driving simulator user trials will be presented to demonstrate how these devices were used to estimate level of workload in real-time while driving under distinctive task complexities. For instance, heart rate, captured using Empatica E4, BASIS Peak Smartwatch, and Polar H7 Heart Monitor, has revealed some patterns that can be related to workload. For instance, Heart Rate Variability (HRV) was significantly affected by variations in driving workload e.g., the highest HRV was measured during the lowest complexity driving, and vice versa. Additionally, electrodermal activity, peripheral body temperature, and various emotions were captured and analysed. To conclude, the benefits and current limitations of consumer grade electronics in DSM will be discussed. For instance, an ability to evaluate humans’ state prior to actual driving activities can be beneficial; it may enable adaptation of safety and in-vehicle information systems to drivers’ state and as a result counteract fatigue or increased level of workload as early as possible. On the other hand, there are numerous technological and human factors implications that need to be considered when developing a DSM system, ranging from hardware limitations to potentially low user acceptance.
