The device functions by detecting signals in the jaw and face that are triggered by internal thoughts, but are undetectable to human eyes, these signals are then fed to a machine-learning system that is trained to associate certain signals with certain words.

The device includes a pair of bone-conduction headphones, that transmit vibrations to the inner ear through the bones of the face thereby conveying information to the user without interrupting their conversation.

The device is called AlterEgo, created by researchers from Massachusetts Institute of Technology.

Professor Pattie Maes, who oversaw on the study, said:

"At the moment, the use of those devices is very disruptive."

"If I want to look something up that’s relevant to a conversation I’m having, I have to find my phone and type in the passcode and open an app and type in some search keyword, and the whole thing requires that I completely shift attention from my environment and the people that I’m with to the phone itself."

"So, my students and I have for a very long time been experimenting with new form factors and new types of experience that enable people to still benefit from all the wonderful knowledge and services that these devices give us, but do it in a way that lets them remain in the present."

The resulting headset is around 92 per cent in accuracy, but the researchers behind the groundbreaking tech believe it will improve with more training data.
