New Technology: Brain computer interface raises hope of giving ‘voice’ to paralyzed people, know what is the technology

Brain Computer Interface: Scientists have developed a device that can convert brain signals of paralyzed people into words faster than before. This is an important step towards restoring communication among severely paralyzed people.

The wonder of ‘brain-computer interface’

The researchers said that the ‘brain-computer interface’ (BCI) is able to translate brain activity into words faster and more accurately and to incorporate a wider vocabulary than existing techniques.

who have difficulty speaking

People with brain disorders including stroke or ‘amyotrophic lateral sclerosis’ often have severe speech difficulties due to muscle paralysis.

possible to translate brain activity into words

Previous studies suggest that it is possible to verbalize the brain activity of a person with paralysis, but can only do so in writing and with limited speed, accuracy, and vocabulary.

How does technology work?

A recent study published in the journal ‘Nature’ showed that a ‘BCI’ that collects the neural activity of single cells via 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 50-word vocabulary, which is 2.7 times fewer errors than previous state-of-the-art BCIs by 2021. (courtesy of input language)
