Meta researchers are developing a gesture-controlled wristband that can interact with a computer
Meta researchers are developing a wristband that lets people control a computer using hand gestures. This includes moving a cursor, opening apps, and sending messages by writing in the air as if using a pencil. Meta's wristband employs a technique called surface electromyography (sEMG), which detects electrical signals generated by muscle activity to interpret user movements, as explained in a research paper published in the journal Nature. These signals can sense a person's intended actions, even before they do them. The goal of this wristband is to provide less invasive tools to interact with computers for people with motor disabilities. The company is collaborating with Carnegie Mellon to test the wristband with people who have spinal cord injuries, enabling them to use computers even if they are unable to fully use their arms or hands. Douglas Weber, a professor in the Department of Mechanical Engineering and the Neuroscience Institute, noted that even people with complete hand paralysis still exhibit some muscle activity. As a result, the device is able to interpret their intended actions. The wristband is a simpler alternative to other projects, such as Elon Musk's Neuralink, which aims to implant brain chips in individuals with severe paralysis. Other non-invasive approaches include headsets that utilize electroencephalogram (EEG) signals; however, these have limitations due to the weak signals they produce. Meanwhile, Meta's wristband could be used immediately without surgical intervention, and its use of sEMG signals means it operates at a higher frequency than EEG. 擷取數據時發生錯誤 登入存取你的投資組合 擷取數據時發生錯誤 擷取數據時發生錯誤 擷取數據時發生錯誤 擷取數據時發生錯誤

A closer look at Meta's wristband for controlling devices.
Posted Jul 23, 2025 at 4:00 PM UTC A closer look at Meta's wristband for controlling devices. Meta's hinted at this kind of wristband before, but The New York Times just published a deeper dive based on a research paper published in Nature . The neat thing is it can 'predict' what you're going to do based on electrical signals sent from your brain through your muscles. This isn't a new concept. Third-party straps like the Mudra Band do similar things. But according to my colleague Alex Heath, this particular band will launch at Connect with Meta's Hypernova glasses.

Meta Unveils Wristband for Controlling Computers With Hand Gestures
The prototype looks like a giant rectangular wristwatch. But it doesn't tell the time: It lets you control a computer from across the room simply by moving your hand. With a gentle turn of the wrist, you can push a cursor across your laptop screen. If you tap your thumb against your forefinger, you can open an app on your desktop computer. And when you write your name in the air, as if you were holding a pencil, the letters will appear on your smartphone. Designed by researchers at Meta, the tech giant that owns Facebook, Instagram and WhatsApp, this experimental technology reads the electrical signals that pulse through your muscles when you move your fingers. These signals, generated by commands sent from your brain, can reveal what you are about to do even before you do it, as the company detailed in a research paper published on Wednesday in the journal Nature. With a little practice, you can even move your laptop cursor simply by producing the right thought. 'You don't have to actually move,' Thomas Reardon, the Meta vice president of research who leads the project, said in an interview. 'You just have to intend the move.' Meta's wristband is part of a sweeping effort to develop technologies that let wearers control their personal devices without touching them. The aim is to provide simpler, quicker and less awkward ways of interacting with everything from laptops to smartphones — and maybe even to develop new digital devices that replace what we all use today. Most of these technologies are years away from widespread use. They typically involve tiny devices surgically implanted in the body, which is a complicated and risky endeavor. These implants are tested solely with disabled people who cannot move their arms and hands, and need new ways of using computers or smartphones. Want all of The Times? Subscribe.
