Artificial intelligence helps paralyzed people to write by hand using thoughts
Source:to Write by hand even the power of thought
Every year thousands of people around the world face various neurological diseases such as stroke and injury of the spinal cord. As a result of these diseases many of them cease to move some of the limbs, that is, they have a palsy. Such people almost completely lose the ability to communicate with doctors and relatives, therefore without the use of expensive equipment, sometimes just impossible to do. In the world there are already technology to read thoughts and convert them into text messaging with speed , but recently scientists from the us state of Illinois has managed to improve this indicator. In this they were helped by artificial intelligence.
About the new development of scientists told the publication in reference to . In the published article describes an experiment in which a new technology gets the ability to communicate the patient with the so-called tetraplegia. This term refers to paralysis of the arms and legs caused by compression or division of the spinal cord due to an accident.
Communication by means of thoughts
In the course of the experiment a patient with brain-implanted electrodes were like he moves his arm if he wrote specific letters of the alphabet. When writing each character's brain we were given different activity that memorable artificial intelligence. In the end, the computer was able to remember the activity in the brain corresponds to each letter of the alphabet and subsequently able to turn to give on-screen characters, who mentally drew the patient.
Characters that are mentally wrote volunteer
According to the researchers, the artificial intelligence learned to recognize the characters with accuracy up to 95%. Mostly the error occurs only when recognizing similar letters, like "q" and "g". Albeit with some mistakes, but thanks to new technology, a paralyzed man was able to print text with a speed of 66 characters per minute. For comparison, the normal speed of writing person is about 120 characters per minute.
The authors of the study believe that this is not the limit. Artificial intelligence capable of learning, so soon it will certainly increase the recognition accuracy of letters. This means that error words will be in times less, and the input speed information will increase.
the company Neuralink?
It should be borne in mind that the researchers also important to improve the technology of reading information from the brain. At the moment this deals with a huge number of companies and one of the most famous is under the leadership of Elon musk. It was founded in 2016 and for a long time about the developed technology was little known.
However, the company recently shared the details and told that to read thoughts of the person they intend to use a thin filament with a thickness of 4 to 6 micrometers. According to the company, they are not able to cause human brain harm, but having a good information. For implantation of the electrodes, by the way, will be used .
