Could we have a computing platform that's more internal, that melds human and machine in some ways and that feels like an internal extension of our own cognition?" Arnav Kapur, MIT Media Lab

Additionally, the system can communicate with the user via a pair of "bone-conducting headphones" by transmitting vibrations from the face to the ear. The headphones are meant to effectively convey information to the user without interrupting their conversation or hearing. The researchers tested the device with different tasks, including games of chess and basic multiplication and addition problems, using limited vocabularies of 20 words.
To create the device, the researchers had to figure out the locations on the face that had the most reliable neuromuscular signals. To do so, they asked subjects "to subvocalize the same series of words four times," and used 16 electrodes at different facial locations to detect the signals.

"We're in the middle of collecting data, and the results look nice. I think we'll achieve full conversation some day." Arnav Kapur, MIT Media Lab

Another example of using the headset is in selecting a movie to watch by controlling what's selected on a TV, as demonstrated in the video.
