Meta builds gesture-based wristband for hands-free device control: Report
Meta is developing a gesture-controlled wristband that can let users operate computers and digital devices using subtle hand movements. According to a post on the Meta blog, the device uses muscle signals to control actions like moving a cursor, launching apps, and sending messages – all without touching a screen or keyboard. The wristband is designed to function across a wide range of physical abilities. Users can 'write' in the air or on surfaces such as a table or their leg, mimicking pencil-like motion, to compose messages or interact with menus. Surface electromyography (sEMG): How it works The core of the technology is surface electromyography (sEMG), a non-invasive method that detects electrical signals generated by muscle activity. These signals, captured by sensors embedded in the wristband, can be interpreted even before a physical gesture is made. Meta is collaborating with Carnegie Mellon University to test the wristband's usability for individuals with spinal cord injuries. According to Douglas Weber, professor at Carnegie Mellon's Department of Mechanical Engineering and the Neuroscience Institute, even people with complete hand paralysis exhibit some residual muscle activity, which the device can detect and interpret. Integration with AR and accessibility Meta has developed an sEMG wristband prototype that integrates with its Orion AR glasses. This enables users to perform actions like typing, navigating menus, and sending messages hands-free, using only neuromotor signals at the wrist. The wristband supports gesture recognition such as tapping, swiping, and pinching even when a user's hand is resting. It also features handwriting recognition, allowing users to write messages by mimicking pen movements on any surface. Key advantages of Meta's sEMG wristband

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
