Summary

Story summary

Tsinghua University researchers in Beijing are developing a safety upgrade for self-driving cars using functional Near-Infrared Spectroscopy (fNIRS) to monitor passengers' brain activity.
The algorithm analyzes stress and emotions to adjust the vehicle's driving strategy based on detected risk.
Initial tests showed the method outperformed traditional systems and suggested safer, more efficient decisions.
Researchers cite limitations from simple driving scenarios and participant demographics and plan validation in more complex situations.
