Experiments show that you can really control people's brains through the Internet.

Researchers at the University of Washington discovered a year ago that "brain-brain communication in brain waves" can be achieved in real life. Now they have completed a series of experiments to prove that last year's success was not a fluke. In this experiment, the test team was tested by 2 people and increased to 6. Each of the two individuals is divided into one group, which acts as the sender and receiver of the signal, and the EEG connects the sender to read the brain waves. Each group of two people need to play with each other in a computer game, manipulating the cannon to keep the city safe. In the experiment, the sender and receiver can not manipulate the game directly, the sender sends the command signal through the brain wave, the signal stimulates the receiver's brain to manipulate the finger for the game.

The staff put a cap-like device on the head of the signal receiver, and the data coils were wrapped around the brain's control of the hand movement. In the experiment, the receiver could not see the game, but their fingers were placed on the trackpad to control the cannon. In the instant the sender transmits the signal, the receiver of the game can be judged and the game can be manipulated through the fingers. Although the accuracy of the cannon firing was only maintained between 25% and 83%, most of the errors were due to the wrong direction of the sender, which resulted in the operator error of the response.

The team says they have now won 1 million of dollars in support and are planning to do more in-depth experiments, such as trying to convey complex ideas or points of view between subjects. In addition, the team is trying to find good ways to help partners to be more agile in their work, such as allowing pilots and co-pilot to interact with each other, or allowing two of people to communicate knowledge to each other. "Because of the limitations of language, complex knowledge is difficult to express," said Chantel Prat, a member of the experimental team. Suppose there is a genius scientist, but he is not a qualified teacher, it is valuable to help him to pass the thought to others. ”
