Scientists say the new mind-reading machine will help patients who are unable to speak
Researchers at the University of California have developed a new mind-reading machine that is capable of translating human thoughts into texts, the Daily Mail reported. Until now, the mind-reading machine was used by late physicist Stephen Hawking to translate his thoughts into voice.
According to study leader, David Moses, the mind-reading machine has an accuracy rate of 90 percent or more and it works by understanding consonants and vowels in our brains. The machine is expected to help several patients who are unable to move or speak despite being mentally active. The device is explained in the Journal of Neural Engineering.
So, how does the mind-reading machine works? Basically, electrodes are implanted in the brain and linked to a computer that translates electrical signals transmitted by the brain. Then, these thoughts are translated into words, which appear on a monitor screen.
“No published work has demonstrated real-time classi?cation of sentences from neural signals. Given the performance exhibited by [the machine] in this work and its capacity for expansion, we are con?dent in its ability to serve as a platform for the proposed speech prosthetic device,” Moses added.
However, critics fear that the device could cause serious problems if secret or embarrassing human thoughts are exposed accidentally.
Uri Geller, well-known celebrity mind-reader said that: “I can imagine circumstances where it may reveal some hugely embarrassing thoughts.
“This will strike fear into some people because we all have hidden secrets!”
