In many topics in the field of robotics, the “brain-computer interface†is almost a constant topic, because it exists in the scientist’s world in a mysterious and unimaginable state. trick. 
Maybe you would think that the brain-computer interface is to help people like Hawking gradually become frozen, the patient recovers the ability to successfully communicate with the outside world, or to help those who have money and fear of death to obtain eternal life, or to use ideas like Avatar. Control another body to make a wonderful trip in outer space... In short, the "brain-computer interface" is incomparably tall, far away from us who eat melons. However, the latest scientific progress tells us that the brain-computer interface is actually very close to us, because every person who eats melon has a ubiquitous disease - lazy cancer (early, middle, late ...), if there is a lot of things to use Is it cool? We know that the brain-computer interface is divided into two types of extracranial and implantable. Because of the high safety outside the brain, because it does not require surgery, it has already been used in industrial applications. The above picture is a "meeting cat ears" made by Neuroware, a Japanese company, using a brain-machine interface chip. The two ears on the headband can produce corresponding actions according to the wearer's emotional changes. When your mood is depressed, your ears will droop, ears will stand when your concentration is focused, and your ears will sway when you are happy. Of course, this product is still in pure entertainment. At the beginning of 2016, a company called BrianCo developed a brain wear device Focus 1, which is considered to be outstanding in non-invasive brain-machine interface. This is of course because it has reached the level of assisted lazy cancer patients. To the depth of the development of the effect. For example, it can use ideas to control smart home products, such as switching lights, curtains, ah, you just need to concentrate on thinking about it can be completed. The following video is a video of their CES conference in Las Vegas. The audience brings a headband to control the color of the lights with ideas. The research on the invasive brain-computer interface is even more exciting. Just over a month ago, Stanford University in the United States announced their breakthrough progress. People can type through the brain-computer interface. The old man named Dennis Degray on the picture is 64 years old this year. He fell for 10 years ago, causing spinal cord injuries and quadriplegia. Stanford researchers implanted a small sensor in the cortex of his brain. Although Dennis Degray's arm does not move, the neurons in this sport cortex are still active. So, as long as Dennis Degray imagines moving his hand with his mind, the neurons of the brain can also send out corresponding electrical signals. Sensors implanted in the brain of the elderly will receive these electrical signals and transmit them to the brain-computer interface. Therefore, such a brain-machine interface helped Dennis Degray use his mind to control the mouse on the computer's desktop to complete the task of typing. In a publicly released video, Dennis Degray successfully made the phrase "The quick brown fox jumps over the lazy dog." Of course, their typing speed is still very slow. Now, participants in this study can type 20 to 40 characters per minute, which is equivalent to 4 and 8 words per minute. Researchers at Stanford University say: At present, thousands of people walk with devices in their heads every day. If, five years ago, you asked me if I could see such results in my lifetime, I would be skeptical. But now I want to say that within the next 10 years, we will be able to see systems that help the deaf to restore functionality. Of course, for us, it is one day we lie in bed, listen to music, and use our ideas to order a delicious meal. And authoritative researchers have told us that early embryonic forms within 10 years can be realized.
