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.<ref>meta_official_emg</ref>

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.<ref>meta_connect_2025</ref> The device is exclusively bundled with [[Meta Ray-Ban Display]] glasses, priced at $799 USD for the combined package.<ref>uploadvr_handson</ref>

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.<ref>ctrl_labs_acquisition</ref> CTRL Labs had been developing wrist-based EMG technology since at least 2015, pioneering the use of muscle signal detection for computer input.<ref>techspot_emg</ref>

[[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.<ref>reardon_meta</ref> Under his leadership, the project evolved from early research prototypes into a consumer-ready product.

Meta first publicly demonstrated its EMG wristband technology in March 2021, showcasing research prototypes capable of detecting individual neuron activity.<ref>meta_2021_demo</ref> 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.<ref>nature_paper</ref>

In July 2025, Meta published peer-reviewed research in the scientific journal ''[[Nature]]'', titled "A generic non-invasive neuromotor interface for human-computer interaction."<ref>nature_publication</ref> 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.<ref>nature_metrics</ref>

The neural wristband was first demonstrated publicly as a prototype paired with Meta's [[Orion AR glasses]] at [[Meta Connect 2024]] in September 2024.<ref>orion_demo</ref> 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.<ref>ceres_codename</ref>

[[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.<ref>zuckerberg_timeline</ref>

The Meta Neural Band employs [[surface electromyography]] (sEMG) technology, which measures electrical activity produced by [[skeletal muscles]].<ref>emg_technology</ref> 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.<ref>semg_explanation</ref>

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.<ref>sensor_array</ref> This approach offers several advantages over optical tracking:

* '''Zero occlusion issues''': Functions regardless of hand visibility or lighting conditions, including complete darkness<ref>darkness_functionality</ref>

* '''Low latency''': Can detect neural signals before fingers visibly move, potentially achieving negative latency<ref>negative_latency</ref>

* '''Subtle input''': Allows control with minimal movement, enabling interaction while hands rest at the user's side, in pockets, or on lap<ref>subtle_gesture</ref>

* '''High precision''': Provides accurate finger tracking without the need for exaggerated movements<ref>precision_tracking</ref>

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.<ref>no_calibration</ref> 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.<ref>ml_training</ref>

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

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]].<ref>vectran_material</ref> This material provides exceptional strength when pulled while remaining soft and flexible for comfortable all-day wear.<ref>material_properties</ref>

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

The Meta Neural Band recognizes four primary gestures in its initial consumer release:<ref>four_gestures</ref>

| Thumb-to-Index Pinch || Click/Select || Primary selection gesture for activating buttons and links<ref>pinch_click</ref>

| Thumb-to-Middle Pinch || Back/Menu || Single tap returns to previous screen; double tap toggles display on/off<ref>middle_pinch</ref>

| Thumb Swipe || Scroll || Swiping thumb against side of index finger acts as virtual D-pad for scrolling content<ref>thumb_swipe</ref>

| Pinch-and-Twist || Volume/Zoom || Pinching with thumb and index finger while rotating wrist adjusts volume or camera zoom<ref>pinch_twist</ref>

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.<ref>hands_down_interaction</ref>

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.<ref>handwriting_update</ref> Research demonstrations have shown the system capable of recognizing handwritten input at approximately 20.9 words per minute, with potential for improvement through personalization.<ref>handwriting_speed</ref>

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

The Meta Neural Band is designed to work exclusively with [[Meta Ray-Ban Display]] glasses in its first consumer release.<ref>rayban_exclusive</ref> The device requires:

* Internet connection for [[cloud]]-enabled features<ref>system_requirements</ref>

* '''[[Orion]] AR Glasses''': Meta's prototype true AR glasses demonstrated at Connect 2024, featuring 70-degree field of view<ref>orion_compatibility</ref>

* '''Future AR Glasses''': Consumer versions of true AR glasses planned for release around 2027<ref>future_ar_glasses</ref>

* '''Potential Standalone Use''': [[Mark Zuckerberg]] has suggested the wristband could evolve into its own platform, potentially controlling devices beyond Meta's ecosystem<ref>standalone_potential</ref>

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.<ref>display_specs</ref> Users can navigate the glasses' interface to:

* 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<ref>glasses_features</ref>

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

* Users with fewer than five fingers<ref>accessibility_applications</ref>

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.<ref>reduced_movement_benefit</ref>

Early hands-on reviews from [[Meta Connect 2025]] praised the Meta Neural Band's performance, with several reviewers describing it as working "like magic."<ref>magic_reviews</ref> ''[[UploadVR]]'' reported a 100% gesture recognition success rate during their testing session, with immediate haptic feedback confirming each detected gesture.<ref>uploadvr_success_rate</ref> ''[[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."<ref>roadtovr_review</ref>

''[[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.<ref>tomsguide_review</ref>

The ''Nature'' publication of Meta's research was recognized as a significant milestone in [[brain-computer interface]] (BCI) and [[human-computer interaction]] (HCI) fields.<ref>nature_significance</ref> 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."<ref>farina_quote</ref>

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

* Select [[Verizon]] stores<ref>retail_locations</ref>

Purchase requires scheduling an in-person demonstration and professional fitting to ensure proper wristband size selection.<ref>demo_requirement</ref>

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

At [[Consumer Electronics Show|CES]] 2025, a competing device called [[Mudra Link]] was demonstrated, offering similar EMG-based gesture control for $199.<ref>mudra_link</ref> 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.<ref>mudra_features</ref>

* '''[[Optical hand tracking]]''': Used by [[Meta Quest]] headsets and [[Apple Vision Pro]], relies on cameras and has occlusion limitations<ref>optical_comparison</ref>

* '''[[Controllers]]''': Traditional handheld input devices offering precise control but requiring users to hold and manipulate physical objects<ref>controller_comparison</ref>

* '''[[Voice input]]''': Speech-based control that may be socially awkward or impractical in certain environments<ref>voice_comparison</ref>

* '''[[Eye tracking]]''': Gaze-based selection used in devices like [[Apple Vision Pro]], often combined with hand gestures<ref>eye_tracking_comparison</ref>

Meta released extensive documentation of its EMG research to the scientific community:<ref>scientific_release</ref>

* '''Nature Paper''': "A generic non-invasive neuromotor interface for human-computer interaction" (July 2025)<ref>nature_paper_full</ref>

* '''Public Dataset''': Over 100 hours of sEMG recordings from 100 participants per task type (discrete gestures, handwriting, wrist movements)<ref>dataset_release</ref>

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).<ref>paper_authors</ref> The three-page contributor list indicated the extensive collaborative effort behind the project's development.<ref>contributor_list</ref>

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.<ref>paradigm_shift</ref> [[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]].<ref>zuckerberg_vision</ref>

Meta emphasizes that the Neural Band only reads outgoing motor signals from the brain to muscles, and cannot "read minds" or access thoughts.<ref>not_mind_reading</ref> [[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."<ref>reardon_clarification</ref> All signal processing occurs locally on the device, with no raw EMG data transmitted to Meta's servers.<ref>local_privacy</ref>
