As the test participants say the words in their mind, they can move the pointer on the monitor. It’s meaningful to those people who lost the power of speech because of the brain damage.
As to the news, the American scientists have developed the computer controled by the mind. The breakthrough may provide the help to those disable and speechless people. It can help disabled people to control the wheelchair or robotic arm. It can even change the computer game industry fully. The Doctor Eric Leuthardt of the Washington University in Saint Louis, Missouri said, “The earliest example is called ‘though reading’. It has limited involved coverage.”
Leuthardt connects the brain of the participant and computer through the ECoG technology. They plant the electrode in people’s brain to record the electronic activity of the brain. In previous time, people make use of the technology to confirm the epilepsy caused brain region and develop the effective treatment method.
In the test process, the signal sent by the electrode will be received and recorded on the computer. The research result is published on the Journal of Neural Engineering.
The researchers said the participants can control the computer expertly soon and requires no much training. They hope they can plant the implant to the brain of the patient and help them to communicate with others. And they can even make use of the computer to learn their ideas.
