Back in April , at Facebook ’s yearly developer conference , the company announcedan ambitious — and very creepy!—plan to scan its users ’ judgment . Facebook ’s secretive computer hardware R&D division , Building 8 , planned to germinate its own “ brain - to - estimator interface ” hardware that would allow a drug user to send word straight from her mastermind to a computer by merely thinking . But until now , we ’ve try scant details as to how exactly Facebook plans to accomplish this .
“ It sound impossible , ” work up 8 head Regina Dugan said at the time . “ But it ’s closer than you may realize . ” Within “ a few years , ” she said , her researchers aimed to create a system that let people type with their thoughts three metre faster than you could typecast with a smartphone .
Speaking at an MIT Media Lab league on Monday , undertaking head and neuroscientist Mark Chevillet dropped some more pinch as to how this long - shot goal might be achieved .
His squad , he told the hearing , plans to use noninvasive sensor to observe brain signal link up with a person reckon a word , then habituate an algorithm to visualize out what the intended word was , concord to a report of the league by STAT News . Artificial intelligence will also belike figure in , help to determine which of several potential quarrel is actually the one a substance abuser was cerebrate of . And the squad is leaning towards using a technology call diffuse optimum tomography to draw in all of this off , which would work by shining near - infrared twinkle onto mastermind tissue , and infer shape of neuron free-base on how the light scatter .
consort to STAT , Chevillet pegged the technology as a solution to the fact that people do n’t care to practice voice recognition to send textual matter when they ’re in earreach of others , even though its a faster mode of typing .
Fact : masses do n’t like using vocalism assistants in front of other people . Facebook : What if you could type from your brain?#digitalneuro

Facebook is hardly the first to set out to make a working head - computer interface . DARPA , which Dugan used to head , hasinvested heavilyin genius - information processing system user interface engineering to do things like treat mental illness , and restore retentiveness to soldiers injured in war . More latterly , Silicon Valley has been lock in an arms race to build a brain computer interface that allow us to transmit by thought . before this year , Tesla and SpaceX head Elon Musk give away anew simple machine - wit interface company , Neuralink . So did Silicon Valley entrepreneurBryan Johnson(that one ’s called Kernel ) andFacebook alum Mary Louise Jepsen(Open Water ) .
And while they might seem like science fiction , brain - calculator interfaces have already had some impressive succeeder . Researchers have used such system to permit mass with disabilities to verify paralytic or prosthetic limbs . But stimulating the brain ’s motor lens cortex is a lot simpler than reading a person ’s thoughts and then translating those thoughts into something that might be read by a computing machine . That engineering science is still in its infancy , and some scientists are skeptical that the technology will ever subsist . Others raise their eyebrows at the thought of doing it “ within a few class . ”
Diffuse optical tomography , which Chevillet order his team might employ , is a engineering science already more than a ten old that can successfully picture bombastic sections of the brain all at once . But even so , for now it can not peer very deep into the brain , and it only lead off to draw near the spirit level of detail obtain with an fMRI .
Facebook ’s end goal is to build an on-line world that feels more immersive and material . That may be a hard sell , though , if doing so requires substance abuser to assume something that lookslike this .
