Enhancing Road Safety and Vehicle Efficiency through Biometric Studies in Virtual Driving Environments
=====================================================
Autonomous vehicles (AVs) are poised to revolutionize the way we travel, reducing human driving errors and potentially saving lives. A new approach to enhancing the performance and safety of AVs during critical transition phases involves the use of biosensors.
These sensors, integrated into wearables or vehicle seats, monitor human attention and interaction by tracking vital physiological and cognitive states. They capture real-time biometrics such as heart rate variability, skin conductance, brain activity, and eye movements to assess driver alertness, stress levels, and readiness to take control from the self-driving system.
One key application of biosensors is monitoring driver attention and workload. By measuring parameters like eye tracking, EEG signals, and heart rate variability, these sensors can detect signs of fatigue, distraction, or reduced vigilance. This information helps the autonomous system assess if the human driver is prepared to intervene safely during handover or emergency transitions from autonomous to manual mode.
Another application is adaptive human-machine interaction. By analysing biometric data in real time, the vehicle can tailor alerts, warnings, or control interfaces to the driver's current cognitive and emotional state, reducing confusion or delayed responses during transition phases.
Biosensors can also predict and prevent unsafe behaviour. AI-powered sensors can predict panic attacks or stress spikes with high accuracy by analysing biometric patterns, enabling preemptive action such as calming notifications or safety measures before driver engagement becomes unsafe.
Aggregated biosensor data can inform digital twin models of human drivers, supporting the optimization of autonomous vehicle algorithms to better manage handover situations based on validated human attention and interaction profiles.
This approach leverages advances in wearable biosensors for real-time physiological monitoring, AI analytics to interpret biometrics, and integration with vehicle control systems to enhance safety during the critical transition from non-autonomous to self-driving modes. The primary benefits include reduced accident risk from human error, optimized timing and modality of handover alerts, and personalized support to maintain driver readiness.
While direct references discussing biosensors for human attention specifically in autonomous vehicle transitions are limited, the synthesis of current wearable biosensor technologies and human digital twin research strongly supports their role in improving performance and safety during such transition phases.
As AVs come to the market, the interaction of human drivers with these vehicles will present a new scene for error, since human drivers may not be sure how an autonomous vehicle will behave in urban driving scenarios. However, the use of biosensors could help mitigate these risks, ensuring a smoother and safer transition to self-driving technology.
