Mark Zuckerberg's firm have completed early tests for an interface which will enable humans to type with their thoughts via a wearable device.

The social media giant's Facebook Reality Labs has been working with researchers at the University of California to create the tech.

According to a study published by the journal Nature Communications, they were able to take speech directly from the brain using the device.

For the study, they worked with three people being treated for epilepsy who had electrodes implanted into their brains.

They plan to spend the next 12 months working on perfecting the innovation.

The device could help people who have suffered brain injuries in the future.

But for now the focus is on Facebook's Augmented Reality (AR) glasses.

Andrew 'Boz' Bosworth, Facebook vice president of AR/VR, tweeted: "Today we're sharing an update on our work to build a non-invasive wearable device that lets people type just by imagining what they want to say.

"Our progress shows real potential in how future inputs and interactions with AR glasses could one day look."
