From the article:
A paralysed man has used a brain-computer to write on a screen at speeds almost as fast as an able-bodied adult, according to a new study.
Researchers have developed a method of communication for people with paralysis that uses a computer to turn mental handwriting into on-screen words. A computer decodes attempted handwriting movements from brain signals, and may allow much faster communication than was previously possible, scientists say.
They report that a combination of mental effort and state-of-the-art technology have allowed a man with immobilised limbs to communicate by text at speeds rivalling those achieved by his able-bodied peers texting on a smartphone.
The team, based at Stanford University, coupled artificial-intelligence software with a device, called a brain-computer interface (BCI), implanted in the man’s brain.
The software was able to decode information from the computer to quickly convert the man’s thoughts about handwriting into text on a computer screen, according to the study published in Nature.
The man was able to write using this approach more than twice as quickly as he could using a previous method developed by the Stanford researchers, who reported those findings in 2017 in the journal eLife.
“This approach allowed a person with paralysis to compose sentences at speeds nearly comparable to those of able-bodied adults of the same age typing on a smartphone,” said Prof Jaimie Henderson of Stanford University. “The goal is to restore the ability to communicate by text.”
