The brain-computer interface allows you to transmit thoughts

Adam Wilson, a graduate student at the University of Wisconsin-Madison specializing in biomedical engineering, and colleagues Justin Williams and Gerwin Schalk have developed a brain–computer interface that allows typing texts on a virtual keyboard literally with the power of thought.

The user puts an elastic cap with electrodes on his head and carefully looks at one of the symbols on the virtual keyboard – until the computer analyzes the activity of neurons and displays the desired letter on the screen.

According to the developers, it is not difficult to master mental work on a computer, and with each workout, users type messages faster and faster. However, judging by the video, even the author of the development takes about half a minute for each letter. Therefore, Wilson sends messages to his microblog on Twitter.com : in this popular social network, the message length is limited to 140 characters. If you look closely, you can see on the virtual keyboard a key with the inscription “tweet” in the place where the “Enter” or “send” button should be.

The first of the four texts happily announces: "Sent from BCI2000" (BCI – "brain-computer interface").

Such an interface, especially if it is possible to increase the speed of character recognition, can significantly improve the quality of life of many disabled people (for example, after a spinal cord injury), giving them the opportunity to communicate online no worse than healthy people.
