Facebook-backed researchers have managed to translate brain signals into spoken words, bringing the social network’s vision of linking brains and machines closer to reality.

A study published this week by University of California-San Francisco scientists showed progress toward a new type of brain-computer interface. The project involved brain implants, but could be a step toward accomplishing the goal with a non-invasive method such as augmented reality glasses with sensors.

“A decade from now, the ability to type directly from our brains may be accepted as a given,” Facebook said Tuesday in an online post updating a project announced two years ago.

“Not long ago, it sounded like science fiction. Now, it feels within plausible reach.”
