The mind-reading AlterEgo headset (almost) promises telepathy with Alexa - Andy Boxall, Digital Trends

What if you could “speak” to a voice assistant only by thinking about the words you want to say? Considerably less embarrassing. right? That’s the basic concept behind the AlterEgo, a prototype mind-reading wearable designed by researchers at the Massachusetts Institute of Technology (MIT). How it works is extremely clever. OK, it doesn’t quite read your mind, but instead it reads something called subvocalization. This is the name given to tiny, almost imperceptible neurological and muscular movements made when we say words to ourselves, inside our head. Sixteen electrodes on the prototype AlterEgo headset sense these changes, and match the signals to data inside a special neural network, and eventually activate whatever task was requested. https://www.digitaltrends.com/mobile/mit-alterego-headset-news/
