Researchers at the Massachusetts Institute of Technology developed a device capable of " hearing " and perceive a person's thoughts. It is called AlterEgo and at Unlike other neuroscholes, it's not you need to connect directly to the brain.
How it works
AlterEgo catches the impulses that brain neurons transmit to the facial muscles, tongue and larynx, which are responsible for speech. Roughly speaking, if the word forms in form of thought, then AlterEgo intercepts it before how the word will fly out of the sparrow. Therefore, the gadget itself is more like on helmet, and not jaw retainer - it is in This area contains 7 electrodes that read the signals of the facial muscles. also in kit has headphones for feedback from gadget.
Why it's interesting
Because it's not quite ordinary " neuroshelm " , which was shown in news, not invented how to use it and a year later they forgot. By he is integrates the " mind reader " with voice assistant, allowing you to communicate with gadgets not uttering words aloud. For example, now he can control the set-top box, plyusovat prices in supermarket or memorize the steps in chess.
AT perspective it will work with voice assistants from Amazon and Google, and the design itself will be reduced to the size of portable headphones. But only if the market is interested in this thing. Previous "mind readers " did not fire, because they demanded access to the contents of the cranium, which is not very convenient.
