And today, the company revealed for the first time how far it's come in its quest to make such a device a reality. "Imagine a world where all the knowledge, fun, and utility of today’s smartphones were instantly accessible and completely hands-free," reads a Facebook [blog post]() from today. "Where you could connect with others in a meaningful way, regardless of external distractions, geographic constraints, and even physical disabilities and limitations." The meat of today's announcement: Facebook [says]() it's collaborating with researchers at the University of California in San Francisco to build a device that could help patients with neurological damage speak again by analyzing their brain activity in real time. In [an article]() published in the journal *Nature Communications* today, the team of researchers shared their latest progress on such a device. In the experiments, they asked participants a question and directed them to say the answer out loud. By examining readings from high-density electrocorticography monitors — electrodes that are surgically implanted directly on the surface of the brain — they could figure out the answer with accuracy rates "as high as 61 percent" by looking at brain signals alone. The researchers claim that their results "demonstrate real-time decoding of speech in an interactive, conversational setting, which has important implications for patients who are unable to communicate." But there are plenty of areas that still need work — especially considering the researchers' goal of "real-time decoding speed of 100 words per minute with a 1,000-word vocabulary and word error rate of less than 17 percent," according to Facebook. During the initial trials, the vocabulary of possible answers was extremely limited and the success rate leaves plenty of room for improvement. And then there's the invasiveness of surgically placing electrodes directly on the surface of the brain — a very different model than a sleek headset that's meant for mainstream consumers. But Facebook's Research Lab is already exploring a promising alternative: infrared. By measuring blood oxygenation levels, Facebook believes that it can create a less bulky — and far less invasive — brain-computer interface. In other words, Facebook isn't going to get inside your thoughts any time soon. A device that can allow us all to move a mouse, type Facebook comments, and play games with our thoughts alone is still many years, if not decades, out. And it's also bound to raise plenty of questions concerning privacy. Our thoughts are one of the last safe havens that have yet to be exploited by data hoarding big tech companies. "To me the brain is the one safe place for freedom of thought, of fantasies, and for dissent," Nita Farahany, a professor at Duke University who specializes in neuro-ethics, [told *MIT Technology Review*](). "We’re getting close to crossing the final frontier of privacy in the absence of any protections whatsoever." **READ MORE:** [Facebook is funding brain experiments to create a device that reads your mind]() \[*MIT Technology Review*\] **More on Facebook's device:** *[Zuckerberg: Facebook is Building a Machine to Read Your Thoughts]()* ## Author I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida. ### Author social links [Bluesky]()
