Meta unveiled a wearable prototype that lets users control digital devices by making small hand movements or even thinking about moving. Created by Meta's Reality Labs, the wristband interprets electrical signals from forearm muscles through a technology called electromyography (EMG). With this tool, customers can do things  like navigating a cursor without touching , launching applications, or typing in mid-air, triggering real-time responses on laptops and smartphones. In some cases, actual movement isn’t even necessary; the system can recognize a user’s intent to move.

Driven by AI and Years of Research

The tech decodes neural signals transmitted from the brain to the muscles, catching them before movement takes place. Meta's innovation is the use of artificial intelligence to process huge EMG data sets from more than 10,000 people. The AI based on neural networks—the same type that powers software such as ChatGPT—is able to identify and adapt to typical patterns in muscle signals with great accuracy, even on the first-time user.

No Surgery, No Implants—Just Wear and Use

In contrast to rivals like Neuralink and Synchron, whose products involve surgical implants, Meta's wristband is completely non-surgical. It is a thick smartwatch-looking device that can be used just like a normal accessory. Despite its simplicity, it achieves precise control and speed—potentially allowing users to type faster than by hand.

Accessibility and Future Integration

Aside from daily use for computing, the wristband holds great potential for accessibility. Scientists at Carnegie Mellon are testing the device with patients who have spinal cord injuries. Even if a user is physically restricted in movement, the wristband will be able to pick up residual muscle signals and convert them into digital commands.

From Concept  to Customer

First conceived by Ctrl Labs—a neuroscientist-founded startup acquired by Meta in 2019- the wristband is the culmination of years of development. Now, with enhanced AI capabilities, the product is nearing market readiness.
