Researchers in Switzerland have developed a technology that allows people with disabilities to play video games using only their minds.

The scientists say the ultimate goal of the project is to build a system through which a command can be controlled by its user’s brain signals, helping those with limited mobility.

The program, called ‘Brain Driver’, is being run by people including Samuel Kunz, who was left paralyzed after an accident, writes Scan.

This testing takes a lot of practice and effort, Kunz explains. “I have to be very focused. The connection between my fingers and my brain is gone. I still try to move my fingers just in my head and so it takes a lot of concentration to do it exactly the same way every time,” he said.

So how does it work?

Online avatars are controlled by brain signals, transmitted to computers by electrodes attached to users’ heads, explained Dr Rea Lehner.

“So these electrodes are connected to an amplifier and then to the computer and our algorithms at the end. The algorithms then calculate the brain signal and send commands to the game that our pilot can actually control.”

This process is very complex as brain signals are weak compared to muscle activity.
