- Prototype wristband uses electromyography to detect nerve signals through the skin
- Could replace traditional VR controllers and assist users with mobility impairments
What happened: Neural interface breakthrough
Meta has revealed a working prototype of a wristband that enables computer control through thought-detection technology, as reported by The New York Times. The device, developed by Meta’s Reality Labs team led by CTRL-Labs alumni, employs 128 electrodes to capture electromyographic (EMG) signals from wrist tendons with 95% accuracy in lab tests.
The wristband interprets intended finger movements before they physically occur, allowing users to type in VR or manipulate 3D objects with microgestures. Early trials show response times under 50 milliseconds – faster than conventional input devices, according to published research in Scientific Reports.

Why it’s important
This development marks a significant leap toward seamless human-computer interaction. For the estimated 1 billion people globally with mobility impairments, such technology could revolutionise digital access. Meta’s approach avoids invasive brain implants used by competitors like Neuralink, potentially accelerating regulatory approval.
However, challenges remain. Current prototypes require custom calibration per user, and the $500 estimated production cost may limit accessibility. As EU digital rights groups note, thought-controlled interfaces also raise new privacy concerns about neural data collection that existing laws don’t adequately address.
