The scientists from Freie Universität first used the sensors for measuring brain waves in such a way that a person can move a virtual cube in different directions with the power of his or her thoughts. The test subject thinks of four situations that are associated with driving, for example, “turn left” or “accelerate.” In this way the person trained the computer to interpret bioelectrical wave patterns emitted from his or her brain and to link them to a command that could later be used to control the car. The computer scientists connected the measuring device with the steering, accelerator, and brakes of a computer-controlled vehicle, which made it possible for the subject to influence the movement of the car just using his or her thoughts.
“In our test runs, a driver equipped with EEG sensors was able to control the car with no problem – there was only a slight delay between the envisaged commands and the response of the car,” said Prof. Raúl Rojas, who heads the AutoNOMOS project at Freie Universität Berlin. In a second test version, the car drove largely automatically, but via the EEG sensors the driver was able to determine the direction at intersections.

The AutoNOMOS Project at Freie Universität Berlin is studying the technology for the autonomous vehicles of the future. With the EEG experiments they investigate hybrid control approaches, i.e., those in which people work with machines.
