Summary
This paper presents a systematic review of state-of-the-art technologies for real-time monitoring of driver distraction and inattention, conducted as part of the European H2020 i-DREAMS project. The research is motivated by the significant contribution of human factors, particularly distraction, to road traffic fatalities and injuries globally. The primary objective is to assess existing in-vehicle approaches and recording tools capable of detecting driver mental states and behaviors to mitigate crash risks. The study aims to identify effective, non-intrusive technologies that can be integrated into a context-aware safety envelope for various transport modes, including cars, buses, trucks, and trains. The methodology involved a comprehensive literature search of scientific and grey literature published between 2000 and 2020. The authors screened 624 publications, ultimately analyzing 29 peer-reviewed English-language journals. The review focused on technologies that objectively measure distraction through physiological indicators (e.g., eye movements, heart rate) and behavioral indicators (e.g., vehicle control, reaction time). The assessment criteria included intrusiveness, effectiveness, and transferability across different transportation modes. The results identify several prominent technologies for distraction monitoring. Driver-facing cameras and eye-tracking systems (e.g., Seeing Machines, Smart Eye, Optalert, EyeAlert) were found to be the most frequent and effective solutions, utilizing vision-based metrics such as gaze direction, blink duration, and head pose. These systems are generally non-intrusive and suitable for both simulator and on-road testing. Cardiac sensors integrated into steering wheels (e.g., Cardio Wheel) and wearable devices (e.g., Empatica E4 Wristband) also demonstrated effectiveness in measuring physiological data like electrocardiogram (ECG) and heart rate variability. Conversely, less effective or intrusive approaches included electrode-based wearables requiring finger attachment (e.g., BioRadio, FlexComp) and eye-tracking glasses (e.g., Tobi), which were deemed unsuitable for on-road trials due to calibration difficulties and user intrusion. Smartphone applications were noted as promising low-cost tools for behavioral monitoring but suffer from sensor quality and placement limitations. The study concludes that physiological indicators, particularly eye movements and ECG measures, are the most reliable metrics for continuous distraction monitoring. A significant finding is that most reviewed technologies were validated in driving simulators rather than real-world conditions, largely due to ethical constraints and safety concerns associated with inducing distraction on public roads. However, the authors note that simulator-based technologies are generally transferable across transport modes. The review highlights that established, non-intrusive camera-based systems are the most viable options for real-time implementation, while wearable and electrode-based solutions remain limited to controlled research environments. These insights support the development of robust, scalable monitoring systems for enhancing road safety across diverse vehicle types.
