Artificial Intelligence-Based Depression Detection for Safety-Critical Environments
This study presents an artificial intelligence-based system that combines iris-based identification with the analysis of pupillometric and eye movement biomarkers, enabling the real-time detection of physiological signs of depression before driving or flying. The two-module model was evaluated based on data from 242 participants: the iris identification module operated with an Equal Error Rate of less than 0.5%, while the depression-detecting CNN-LSTM network achieved 89% accuracy and an AUC value of 0.94. This offers a preventive safety solution to reduce human error related to depression in road and air traffic.
Executive Impact
This research demonstrates a significant leap in leveraging AI for proactive safety in transportation. By integrating robust biometric identification with real-time physiological monitoring, the system addresses critical human factors that often lead to catastrophic accidents.

Distinct Physiological Responses in Depression
Depressed individuals showed significantly different pupillary and eye movement responses compared to a neutral state, particularly to emotional stimuli. These patterns are consistent with cognitive distortions characteristic of depression.
| Feature | Control Group Response | Depressed Group Response | Significance |
|---|---|---|---|
| Pupil Dilation (Negative News) | +18.4% increase | +27.9% increase | p < 0.001, large effect size (d=1.17) |
| Pupil Dilation (Positive News) | +6.2% increase | -1.3% (constriction) | p < 0.001, large effect size (d=1.30) |
| Fixation Time (Negative News) | 280 ms | 345 ms | p < 0.001, large effect size (d=1.22) |
| Saccade Speed | 320°/s | 276°/s | p < 0.001, medium-to-large effect size (d=0.90) |

Addressing Limitations and Future Directions
The study acknowledges limitations such as laboratory-controlled environment, participant sample characteristics (non-clinical, untreated), dynamic nature of depression, and non-specificity of physiological patterns. Future work will focus on validating the approach in real-world settings, integrating multimodal sensor data (skin conductance, heart rate variability), and applying Explainable AI (XAI) methods to increase transparency and acceptance. The goal is to move towards robust, personalized, prevention-focused road safety systems.
