Meta researchers are developing a gesture-controlled wristband that can interact with a computer

Meta researchers at Meta Reality Labs are developing a gesture-controlled wristband that enables users to interact with computers through hand gestures, such as moving a cursor, opening applications, and writing messages in the air. The device detects electrical signals generated by muscle activity (sEMG signals) to interpret a user's intended movements, even before they physically execute them. This technology aims to offer a less invasive and more accessible computer interface, particularly benefiting individuals with motor disabilities. The wristband is designed to assist people with spinal cord injuries who may have limited or no hand mobility but still exhibit some muscle activity. Unlike more invasive alternatives, such as Elon Musk’s neural implants, Meta’s device operates without surgical intervention and functions at a higher frequency than EEG-based systems. The researchers plan to test the wristband with users who have paralysis to validate its effectiveness in enabling computer control through subtle muscle signals.
