Japanese scientists have developed a "mind reading" device that can decode the waves emitted by the brain into words that a person has not even had time to pronounce aloud - this opens up new perspectives for creating a "telepathic" connection.
The researchers found that the electrical activity in the human brain is the same when words are spoken out loud and when they are left unspoken.
By comparing the different waveforms generated before speaking certain words, the scientists were able to identify Japanese words such as "sticky", "scissors" and "standard."
According to scientists, they can detect brain waves associated with syllables or letters of the Japanese alphabet - that is, it is possible to decipher entire words and sentences, even when they are not spoken aloud.
To “hear” the unsaid words, the researchers used the electroencephalogram method. They recorded the electrical activity of the brain using multiple electrodes mounted on the head to record brain waves.
The researchers asked 12 men, women, and children to read a series of words while measuring their brain waves.
By compiling a database of different sounds, they found that it is possible to associate existing patterns of brain waves with certain words, even when they are not spoken aloud.
According to data presented at a conference organized by the Institute of Electronics, Information and Communications, the developed algorithms allowed to correctly identify such Japanese words as "haru" and "natsu", meaning "summer" and "spring", 25 percent and 47 percent of the time, respectively.

They were also able to correctly identify individual letters 88 percent of the time.
Professor Toshimasa believes the technology could be used to help paralyzed or speechless people communicate.
In addition, the technology can be adapted to control the power of thought by robotic devices, helping machines interpret the brain's instructions.
In addition, it can be used by astronauts or deep-sea divers for more effective communication in outer space or under water, where sounds are distorted or their transmission is significantly difficult.
