In this modern age, scientists are busy developing new things. In this context, scientists have created a new device, with the help of which the brain waves of paralyzed patients who cannot speak can be analyzed by the computer immediately. can be translated into sentences on the screen. This mind reading machine is capable of tracking the activity of the mind. Experts say that this device will restore the communication ability of stroke patients.
A similar system was presented in earlier research capable of decoding up to 50 words. That machine had a limited vocabulary and the user, who was a paraplegic, had to speak words out loud, which required more effort. So Edward Cheng of the University of California and his colleagues designed a machine capable of converting the brain’s activity into letters, with the help of which an entire sentence comes out.
After building the machine, the researchers used it on paralyzed patients who had difficulty speaking. The authors applied the thinking of previous research to a wider vocabulary by designing this system to decode the association of brain activity with letter sounds. constructed sentences from the vocabulary of , with an average error rate of 6.13 percent.
