Where is technology driving us? On the one hand it is helping us talk to each other. Or perhaps it is taking over the world.

With the advent of wireless technology and remote controllers, our everyday life has been transformed in an amazing way. You can operate almost all electronics, anything from your television to your thermostat, remotely.  Now, integration of Artificial Intelligence with electronics means that you can drive your car without even touching it.

A team of research scientists led by Prof. Raul Rojas at the AutoNOMOS innovations lab of Freie University Berlin have developed an autonomous driving system called the “braindriver”. The car is controlled by the brain signals of the driver. The Electroencephalogram (EEG) was used to collect brain waves corresponding to normal driving functions, such as acceleration, braking, and turning. This information was fed into the software. The software then matches the real-time signals from the driver, as they think about where they want to go, with those stored from the software. It then executes the commands accordingly, with a slight time delay. You can see a video of the test drive at the Tempelhof Airport in Berlin.

The car is equipped with cameras, lasers and sensors so that the software can work with a 360o view of its sorroundings.

While braindriver is far from ready for real life driving, advances are coming. With sufficient improvements, the braindriver will be a boon for those who aren’t physically capable of normal driving.

The real challenge is that the driver must have the utmost focus. Don’t be distracted by the attractive driver in the next car over, or by planning dinner! And texting while driving would be even more dangerous than it is already. If you get angry at a car that almost collided with yours, you may be the next dangerous driver.  I found this video very interesting that shows how the car can deal with you when you get angry while driving (sorry, you got ot listen to the commercial first, if you like to watch the video!). But then how big is the difference in signals between being angry and wanting to accelerate?

If the car gets into an accident, liability is a real issue. Who is responsible? Is it the software, the sensor, the driver or the car manufacturer? A lot of work will be needed to solve these puzzles. If nothing else, it will increase our understanding of the brain itself.

The same research group has previously tested I-phone as well as eye-gaze controlled driving. In a podcast recorded a few months ago, Professor Rojas and the Italian researcher Alberto Broggi, who is also working on autonomous driving, talk about their innovations and their future plans.

An autonomous taxi is another concept that the scientists have tested. With the touch of an I-phone, your car can pick you up, drive you home and park itself in its garage.  This could, theoretically, eliminate the need for personal cars. One technical barrier that still needs to be overcome is facilitating communication and coordination between the autonomous cars.

As a scientist, I am very excited by the technological breakthroughs that my fellow scientists have brought in through autonomous car and the braindriver . But I fear that the mankind will increasingly lead a solo life as the human interaction reduces.
