Meta Platforms(US:META) 生物世界·2025-07-24 07:31Core Viewpoint - The article discusses a groundbreaking non-invasive neuromotor interface developed by Meta's Reality Labs, which allows users to interact with computers through wrist-worn devices that translate muscle signals into computer commands, enhancing human-computer interaction, especially in mobile scenarios [2][3][5]. Group 1: Technology Overview - The research presents a wrist-worn device that enables users to interact with computers through hand gestures, converting muscle-generated electrical signals into computer instructions without the need for personalized calibration or invasive procedures [3][5]. - The device utilizes Bluetooth communication to recognize real-time gestures, facilitating various computer interactions, including virtual navigation and text input at a speed of 20.9 words per minute, compared to an average of 36 words per minute on mobile keyboards [6]. Group 2: Research and Development - The Reality Labs team developed a highly sensitive wristband using training data from thousands of subjects, creating a generic decoding model that accurately translates user inputs without individual calibration, demonstrating performance improvements with increased model size and data [5]. - The research indicates that personalized data can further enhance the performance of the decoding model, suggesting a pathway for creating high-performance biosignal decoders with broad applications [5]. Group 3: Accessibility and Applications - This neuromotor interface offers a wearable communication method for individuals with varying physical abilities, making it suitable for further research into accessibility applications for those with mobility impairments, muscle weakness, amputations, or paralysis [8]. - To promote future research on surface electromyography (sEMG) and its applications, the team has publicly released a database containing over 100 hours of sEMG recordings from 300 subjects across three tasks [9].
