Could Meta be on the verge of transforming how we interact with our digital devices? If the company’s latest innovation takes off, we might soon be controlling our computers, cell phones and tablets with a simple flick of the wrist.

Researchers at Meta’s Reality Labs division have unveiled an experimental wristband that translates hand gestures and subtle finger movements into commands that interact with a computer. This allows a user to push a cursor around a screen or open an app without needing a mouse, touchscreen or keyboard. The technology can even transcribe handwriting in the air into text (currently at a speed of 20.9 words per minute).

In a paper published in Nature, the team describes how its sEMG-RD (surface electromyography research) works. The wristband uses a technique called electromyography to pick up electrical signals when the brain tells the hand to perform an action. It then converts those signals into commands that control a connected device, such as your phone.
