Facebook working on an AR device that will let users type with their mind

San Francisco: Facebook is developing a brain-computer Augmented Reality (AR) interface device that would help users type with their mind.
At its F8 Developers’ Conference in 2017, the company announced its Brain-Computer Interface (BCI) programme — outlining its goal to build a non-invasive, wearable device that lets people type by simply imagining themselves talking.
Facebook is supporting a team of researchers at University of California, San Francisco (UCSF) who are working to help patients with neurological damage speak again by detecting intended speech from brain activity in real time.
