Meta unveils wristband for controlling computers with hand gestures

With a tap of thumb against forefinger, you can open an app on your desktop computer when using an experimental bracelet that reads the electrical signals pulsing through your muscles when you move your fingers. Meta’s wristband is part of a sweeping effort to develop technologies that let wearers control their personal devices without touching them. — Reality Labs, Meta via The New York Times

SAN FRANCISCO: The prototype looks like a giant rectangular wristwatch. But it doesn’t tell the time: It lets you control a computer from across the room simply by moving your hand.

With a gentle turn of the wrist, you can push a cursor across your laptop screen. If you tap your thumb against your forefinger, you can open an app on your desktop computer. And when you write your name in the air, as if you were holding a pencil, the letters will appear on your smartphone.
