brain machine interface – Scientists have developed a device that can convert paralyzed people’s brain signals into words at a faster rate than before. This has been revealed from a recent study published in ‘Nature’ magazine.
Brain Computer Interface: Scientists have developed a device that can convert brain signals of paralyzed people into words at a faster rate than before. This is an important step towards restoring communication between severely paralyzed people.
The wonder of ‘brain-computer interface’
The researchers said the ‘brain-computer interface’ (BCI) is capable of translating brain activity into words faster and more accurately and covering a broader vocabulary than existing technologies.
those who have difficulty speaking
People with brain disorders, including stroke or amyotrophic lateral sclerosis, often have severe speech impairments due to muscle paralysis.
Possible to translate brain activity into words
Previous studies show that it is possible to translate a paralyzed person’s brain activity into words, but only in written form and with limited speed, accuracy, and vocabulary.
How does the technology work?
A recent study published in the journal ‘Nature’ showed that a ‘BCI’ which collects the neural activity of single cells through a series of fine electrodes inserted into the brain, and uses an artificial neural network to convert it into sounds. Trains.
able to communicate
With the help of this device, a patient suffering from ‘Amyotrophic Lateral Sclerosis’ was able to communicate at an average rate of 62 words per minute, which is 3.4 times faster than the previous record for a similar device. The BCI achieved a 9.1 percent word error rate on a vocabulary of 50 words, which is 2.7 times fewer errors than previous state-of-the-art BCIs from 2021. (Courtesy of input language)
