How Brain Signals Could Make Self-Driving Cars Smarter

Self-driving cars are getting better, but they still have trouble in tricky situations. Now, scientists think they have a clever idea: using passengers' brain signals to help these cars make safer choices. Researchers in China tested a system that reads brain activity to understand how passengers feel about risk. They used a tool called fNIRS, which tracks stress and emotions in real time. When the system detects that passengers are nervous, the car can switch to a safer driving mode.The team created a new algorithm that combines brain data with the car's driving software. This helps the car learn faster and make better decisions. In tests, this method worked better than traditional self-driving systems, offering more safety and comfort. However, there are some limitations. The tests were done in simple scenarios with a small group of people. The researchers plan to test the system in more complex situations to make it more accurate and reliable. This study shows that using brain signals could be a big step forward for self-driving cars. It could make them safer and more responsive to human emotions.
