The Meta Neural Band is a wrist-worn electromyography (EMG) input device developed by Meta Platforms through its Reality Labs division. The device uses surface electromyography (sEMG) technology to detect electrical signals from muscle activity in the user's wrist and forearm, translating subtle finger movements and hand gestures into digital commands for controlling augmented reality (AR) and virtual reality (VR) devices.

Announced at Meta Connect 2025 on September 17, 2025, and released on September 30, 2025, the Meta Neural Band represents the first consumer product to emerge from Meta's acquisition of CTRL Labs in 2019. The device is exclusively bundled with Meta Ray-Ban Display glasses, priced at $799 USD for the combined package.

History and Development

CTRL Labs Acquisition

The foundation for the Meta Neural Band traces back to September 2019, when Facebook (later renamed Meta) acquired CTRL Labs, a New York-based startup, for an estimated $500 million to $1 billion. CTRL Labs had been developing wrist-based EMG technology since at least 2015, pioneering the use of muscle signal detection for computer input.

Thomas Reardon, the co-founder and CEO of CTRL Labs and former architect of Internet Explorer, joined Meta as the director of Neuromotor Interfaces at Facebook Reality Labs following the acquisition. Under his leadership, the project evolved from early research prototypes into a consumer-ready product.

Research and Development Timeline

Meta first publicly demonstrated its EMG wristband technology in March 2021, showcasing research prototypes capable of detecting individual neuron activity. The company invested four years of development involving nearly 200,000 research participants to create machine learning models that could generalize across different users without requiring per-person calibration.

In July 2025, Meta published peer-reviewed research in the scientific journal Nature, titled "A generic non-invasive neuromotor interface for human-computer interaction." The paper detailed the technical achievements in creating a high-bandwidth neuromotor interface with out-of-the-box functionality, demonstrating handwriting input at 20.9 words per minute and gesture detection at 0.88 gestures per second.

Product Evolution

The neural wristband was first demonstrated publicly as a prototype paired with Meta's Orion AR glasses at Meta Connect 2024 in September 2024. This prototype, internally codenamed "Ceres," served as a proof of concept for the technology that would later ship with the Meta Ray-Ban Display glasses.

Mark Zuckerberg indicated in early 2024 that the neural wristband would ship as a consumer product "in the next few years," with the actual release occurring in September 2025.

Technology

Electromyography (sEMG)

The Meta Neural Band employs surface electromyography (sEMG) technology, which measures electrical activity produced by skeletal muscles. Unlike traditional hand tracking methods that rely on camera-based computer vision, sEMG detects the electrical signals transmitted from the brain through the nervous system to control muscle movement in the fingers and hand.

The wristband contains multiple sEMG sensors embedded around the circumference of the band, allowing it to capture muscle activation patterns as the user intends to move their fingers. This approach offers several advantages over optical tracking:

• Zero occlusion issues: Functions regardless of hand visibility or lighting conditions, including complete darkness
• Low latency: Can detect neural signals before fingers visibly move, potentially achieving negative latency
• Subtle input: Allows control with minimal movement, enabling interaction while hands rest at the user's side, in pockets, or on lap
• High precision: Provides accurate finger tracking without the need for exaggerated movements

Machine Learning and Generalization

A key breakthrough in the Meta Neural Band is its ability to work "out of the box" for new users without requiring individual calibration or training. Meta's research team collected sEMG data from approximately 10,000 to 200,000 consenting research participants and used deep learning techniques, including neural networks, to identify common patterns in electrical signals across different individuals.

The system's machine learning models process EMG signals locally on-device, ensuring privacy as the raw neural data never leaves the wristband. The models can be further personalized through continued use, potentially improving performance by 16% with user-specific adaptation.

Design and Hardware

Physical Construction

The Meta Neural Band features a lightweight, flexible wristband design made from Vectran, a high-performance synthetic fiber also used in the crash pads of the Mars Rover. This material provides exceptional strength when pulled while remaining soft and flexible for comfortable all-day wear.

The device is available in three sizes (Size 1, 2, and 3) to accommodate different wrist dimensions. Proper fit is critical for optimal sEMG signal detection, requiring professional fitting at authorized retailers before purchase. The wristband is offered in two colors: Black and Sand, matching the available color options for Meta Ray-Ban Display glasses.

Gestures and Input Methods

Current Gesture Set

The Meta Neural Band recognizes four primary gestures in its initial consumer release:

Gesture	Function	Description
Thumb-to-Index Pinch	Click/Select	Primary selection gesture for activating buttons and links
Thumb-to-Middle Pinch	Back/Menu	Single tap returns to previous screen; double tap toggles display on/off
Thumb Swipe	Scroll	Swiping thumb against side of index finger acts as virtual D-pad for scrolling content
Pinch-and-Twist	Volume/Zoom	Pinching with thumb and index finger while rotating wrist adjusts volume or camera zoom

All gestures can be performed with the hand at rest, at the user's side, in a pocket, or on the lap, without requiring the hand to be raised or visible to cameras.

Future Input Methods

Meta announced plans to release a software update in December 2025 that will enable handwriting recognition by allowing users to trace letters on a physical surface (such as their leg) with their index finger. Research demonstrations have shown the system capable of recognizing handwritten input at approximately 20.9 words per minute, with potential for improvement through personalization.

Future capabilities may include virtual keyboard emulation, with Meta previously demonstrating prototypes capable of typing speeds approaching traditional keyboard input by around 2028.

Compatibility and Requirements

Primary Platform

The Meta Neural Band is designed to work exclusively with Meta Ray-Ban Display glasses in its first consumer release. The device requires:

• Meta Ray-Ban Display glasses (included in purchase)
• Compatible smartphone (iOS or Android)
• Meta AI mobile app installed
• Active Meta account
• Internet connection for cloud-enabled features

Future Platforms

Meta has confirmed the Neural Band will serve as the primary input method for future AR products, including:

• Orion AR Glasses: Meta's prototype true AR glasses demonstrated at Connect 2024, featuring 70-degree field of view
• Future AR Glasses: Consumer versions of true AR glasses planned for release around 2027
• Potential Standalone Use: Mark Zuckerberg has suggested the wristband could evolve into its own platform, potentially controlling devices beyond Meta's ecosystem

Applications and Use Cases

Smart Glasses Control

The primary function of the Meta Neural Band is controlling Meta Ray-Ban Display glasses, which feature a monocular heads-up display (HUD) with 600×600 resolution and approximately 20-degree field of view. Users can navigate the glasses' interface to:

• Check notifications
• View Meta AI responses with visual guidance
• Access navigation with turn-by-turn directions
• Control camera and preview photos
• View real-time translations
• Manage media playback

Accessibility

The sEMG-based input method offers significant accessibility benefits for individuals with limited mobility. The technology can detect intended movements even when users cannot produce large physical gestures, making it potentially useful for individuals with:

• Spinal cord injuries
• Stroke survivors with limited motor function
• Conditions causing tremors or involuntary movements
• Users with fewer than five fingers

The ability to control devices with minimal movement while hands rest comfortably addresses challenges faced by users who experience pain or fatigue from traditional input methods.

Reception

Hands-On Reviews

Early hands-on reviews from Meta Connect 2025 praised the Meta Neural Band's performance, with several reviewers describing it as working "like magic." UploadVR reported a 100% gesture recognition success rate during their testing session, with immediate haptic feedback confirming each detected gesture. Road to VR noted that the wristband allows "subtle inputs while your hand is down at your side" and called it "just as important to these new glasses as the display itself."

Tom's Guide described the Meta Ray-Ban Display glasses as "the best smart glasses" they had tested, highlighting the "intuitive wrist gestures" as a key feature.

Technical Achievement

The Nature publication of Meta's research was recognized as a significant milestone in brain-computer interface (BCI) and human-computer interaction (HCI) fields. Dario Farina, a professor of bioengineering at Imperial College London, stated: "This idea – this kind of technology – is not new, it is decades old. The breakthrough here is that Meta has used artificial intelligence to analyse very large amounts of data, from thousands of individuals, and make this technology robust. It now performs at a level it has never reached before."

Challenges

Some reviewers noted that while the Neural Band itself performed flawlessly, the initial Meta Ray-Ban Display glasses had limitations, including:

• Monocular display causing disorientation for some users
• Limited field of view (20 degrees)
• Performance issues with the Qualcomm Snapdragon AR1 Gen 1 chipset
• Weight increase compared to non-display Ray-Ban Meta glasses

Availability and Pricing

Initial Release

The Meta Neural Band launched on September 30, 2025, exclusively bundled with Meta Ray-Ban Display glasses at a combined price of $799 USD. The device cannot be purchased separately and is only available through authorized retailers in the United States, including:

• Best Buy
• LensCrafters
• Sunglass Hut
• Ray-Ban stores

Purchase requires scheduling an in-person demonstration and professional fitting to ensure proper wristband size selection.

International Expansion

Meta announced plans to expand availability to Canada, France, Italy, and the United Kingdom in early 2026. The company stated it would eventually sell the product online after gathering feedback from the initial retail-only launch.

Competing Technologies

Mudra Link

At CES 2025, a competing device called Mudra Link was demonstrated, offering similar EMG-based gesture control for $199. The Mudra Link claims cross-platform compatibility with various AR and XR devices, including TCL RayNeo X3 Pro and Apple Vision Pro, and includes pressure detection features not present in the initial Meta Neural Band release.

Traditional Input Methods

The Meta Neural Band competes with several established input methods for AR/VR:

• Optical hand tracking: Used by Meta Quest headsets and Apple Vision Pro, relies on cameras and has occlusion limitations
• Controllers: Traditional handheld input devices offering precise control but requiring users to hold and manipulate physical objects
• Voice input: Speech-based control that may be socially awkward or impractical in certain environments
• Eye tracking: Gaze-based selection used in devices like Apple Vision Pro, often combined with hand gestures

Scientific Contributions

Published Research

Meta released extensive documentation of its EMG research to the scientific community:

• Nature Paper: "A generic non-invasive neuromotor interface for human-computer interaction" (July 2025)
• Public Dataset: Over 100 hours of sEMG recordings from 100 participants per task type (discrete gestures, handwriting, wrist movements)
• Open Source Code: GitHub repository containing model implementations, training code, and evaluation tools

The research demonstrated three key tasks:

• Discrete Gesture Recognition: 0.88 gesture detections per second
• Continuous Navigation: 0.66 target acquisitions per second
• Handwriting Recognition: 20.9 words per minute (median performance)

Contributors

The Nature paper listed contributions from Meta's Reality Labs team, with lead authors Patrick Kaifosh (Director of Research Science) and Thomas Reardon (Vice President of Neuromotor Interfaces). The three-page contributor list indicated the extensive collaborative effort behind the project's development.

Impact on Computing

Next-Generation Input Paradigm

Meta positions the Neural Band as representing a fundamental shift in human-computer interaction, replacing touchscreens, buttons, and traditional input devices with direct neural signal interpretation. Mark Zuckerberg described it as potentially becoming "a pretty big deal" and suggested it could evolve beyond AR glasses to become a universal input method for controlling all digital devices, including smart home systems, gaming consoles, and computers.

Privacy and Safety

Meta emphasizes that the Neural Band only reads outgoing motor signals from the brain to muscles, and cannot "read minds" or access thoughts. Thomas Reardon clarified: "This is coming from the part of the brain that controls motor information, not thought. It sees what you are about to do." All signal processing occurs locally on the device, with no raw EMG data transmitted to Meta's servers.
