Today Facebook revealed it has a team of 60 engineers working on building a brain-computer interface that will let you type with just your mind without invasive implants. The team plans to use optical imaging to scan your brain a hundred times per second to detect you speaking silently in your head, and translate it into text. The goal is to eventually allow people to type at 100 words per minute, 5X faster than typing on a phone, with just your mind.
Eventually, brain-computer interfaces could let people control augmented reality and virtual reality experiences with their mind instead of a screen or controller. They only began working on the brain typing project six months ago, but it now they are collaborating with UC San Francisco, UC Berkeley, Johns Hopkins Medicine, Johns Hopkins University’s Applied Physics Laboratory and Washington University School of Medicine in St. Louis.
