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's new wristband lets you type and click without touching anything
Researchers at Meta's Reality Labs division are working on a wristband that lets people interact with a computer using simple hand gestures. The company's new product could someday replace the mouse and keyboard and enable users with reduced or limited motor abilities to interact with computers. In a blog post, the tech giant announced that it has successfully tested a prototype wristband with Orion, its highly anticipated first augmented reality glasses. Meta went on to say that the wristband eliminates the need for more cumbersome forms of input and lets users do things like send messages without a keyboard, navigate a menu without a mouse, and see and engage with digital content without having to look down at a smartphone. The wristband can also recognise a wide range of gestures like tapping, pinching and swiping even if your hand is at rest. Moreover, it also supports handwriting recognition, meaning you will be able to write messages on hard surfaces like a desk, table or leg. Since it is easy and natural, the technology can be particularly useful for doing things like sending a private message in public. Meta says it is collaborating with Carnegie Mellon to test its new wristband on people with spinal cord injuries to see if they can use computers even if they are unable to move their arms or hands. Since people with complete hand paralysis show signs of muscle activity, which might mean that the wristband may be able to understand the actions they want to perform. You can watch it in action in the video below. In a paper published in Nature, Meta says its new wristband technology uses a non-invasive technique called surface electromyography, or sEMG for short, which packs several sensors that help convert electrical motor nerve signals travelling through the wrist to the hand into digital commands to control devices. In case you are wondering, these are the very signals sent by the brain to tell your hand to perform certain actions. The company says the model powering the wristband was trained on data from thousands of participating volunteers, making the device highly accurate at understanding subtle gestures across a wide range of people and eliminating the need for individual calibration. Since the new sEMG wristband does not require any operation, Meta says the technology may be able to work for people with 'diverse physical abilities and characteristics.' Compared to Elon Musk's Neuralink, which wants to insert brain chips in individuals with paralysis, Meta's approach is much safer since it requires no surgical insertion and does no damage to the part of the body it's attached to. Meta's new wristband may make its public debut alongside its highly anticipated upcoming smart glasses with a built-in display. Codenamed 'Hypernova', these smartglasses are said to cost somewhere between $1,000 and $1,400 and might be launched sometime later this year.

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
