Some experts are wary of the fledgling brain-computer interface industry, which directly connects machines and minds.

On the 10th floor of a nondescript building at Columbia University, test subjects with electrodes attached to their heads watch a driver’s view of a car going down a street through a virtual reality headset. All the while, images of pianos and sailboats pop up to the left and right of each test subject’s field of vision, drawing their attention.

The experiment, headed by Paul Sajda, a biomedical engineer and the director of Columbia’s Laboratory for Intelligent Imaging and Neural Computing, monitors the subjects’ brain activity through electroencephalography technology (EEG), while the VR headset tracks their eye movement to see where they’re looking — a setup in which a computer interacts directly with brain waves, called a brain computer interface (BCI). In the Columbia experiment, the goal is to use the information from the brain to train artificial intelligence in self-driving cars, so they can monitor when, or if, drivers are paying attention.
