Demo: Meta Reality Labs neural wrist band

We present a novel noninvasive neuromotor interface that enables high-bandwidth human-computer interaction through surface electromyography (sEMG) signals measured at the wrist. Unlike traditional input devices that require physical interaction or invasive brain-computer interfaces limited to individual users, our system leverages subtle neuromotor signals to decode intentional gestures and commands across a broad population without per-person calibration. By combining a sensitive, easy-to-wear hardware platform with a large-scale data infrastructure and advanced neural network decoding models trained on thousands of participants, we achieve robust, real-time gesture recognition and continuous navigation control. This work represents a significant step toward seamless, intuitive, and universal computer input modalities that can scale to the general public, opening new possibilities for mobile and assistive technologies.
