To the left is a video of the driving simulator that the researchers used to demonstrate the viability of their mind-reading setup. According to Dr. Stefan Haufe, the lead author of the study, the secret to the system is EEG (electroencephalography), which the researchers used to first pinpoint the parts of the brain most electrically active in an emergency-braking scenario, and then to respond to signals from those regions as accurately as possible. In the video, you can see the test subject wearing an EEG cap that allows the braking system to monitor his brain waves and help him decelerate more quickly than he could on his own.


The research represents the first time that EEG readings have been used to assist in braking, and the researchers intend to conduct road trials of their mind-reading system in the near future. While aspects of the system remain prohibitive (drivers need to wear an EEG cap, which is uncomfortable and difficult to fit correctly), this research demonstrates the life-saving potential of predictive brain activity, and provides us with a promising glimpse at the future of vehicular safety.
