Meta's new wearable lets you control screens hands-free

The glasses' sensor technology opens up new possibilities for research and development in augmented reality applications. Meta's new gesture control wristband might just be the most seamless way to control a computer yet. And no, it doesn't require surgery, a camera, or even a touchscreen. All it needs is your wrist. This futuristic device uses electrical signals from your muscles to understand what your hand wants to do, even if it never actually moves.
