Meta has unveiled a prototype wristband that enables users to control computers and other devices through hand gestures by reading electrical signals from forearm muscles. The device uses surface electromyography (sEMG) technology, trained on data from 10,000 individuals, to interpret muscle movements without requiring physical touch or surgical implants. This gesture-control wristband allows users to perform actions such as moving a cursor, opening applications, writing in the air, sending messages without a keyboard, and navigating menus without a mouse. Meta’s researchers published their findings in the journal Nature, highlighting the wristband as a simpler alternative to invasive neural interfaces like Neuralink. The technology aims to facilitate seamless human-computer interaction and could integrate with augmented reality devices, representing a potential shift in digital interaction paradigms.
