The Role of Physiological Signals in Stress Detection
Numerous studies have explored the use of physiological signals to monitor driver stress levels and alertness. Signals such as electrocardiogram (ECG), electromyogram (EMG), skin conductance (also known as galvanic skin response or GSR), and respiration rate are more directly associated with a driver’s stress level and are less influenced by external factors like lighting or driving technique. By continuously measuring these physiological signals, advanced driver monitoring systems can detect early signs of stress or fatigue, enabling the vehicle to take proactive measures to enhance driver safety.
A survey on wearable sensors for mental health monitoring, conducted in 2023 with 1,330 participants, highlighted the potential of these physiological signals in stress detection. Similarly, a 2020 study discussed Heart Rate Variability (HRV) as a potential marker of mental health resilience. Additionally, a 2019 survey article investigated stress detection in daily life scenarios using smartphones and wearable sensors.
Researchers have also explored the use of various physiological sensors, including respiration sensors (RIP), electrocardiography (ECG) sensors, GSR sensors, blood volume pulse (BVP) sensors, and electromyogram (EMG) sensors, to measure stress in controlled and free-living conditions. Studies have demonstrated the feasibility of measuring stress with off-the-shelf sensors, such as the Polar H7 heart rate monitoring device, with promising results.
Sensor Type | Stress Detection Performance |
