Meta is developing a wristband that enables computer control through hand gestures like moving a cursor or sending messages. The wristband utilizes surface electromyography (sEMG) to detect muscle activity signals, interpreting user intentions even before actions occur. It aims to assist individuals with motor disabilities by providing non-invasive interaction methods. Collaboration with Carnegie Mellon focuses on testing the device with those who have spinal cord injuries. Unlike invasive approaches like Neuralink, the wristband offers immediate usability without surgery and operates on more robust signal frequencies compared to EEG headsets.
Meta's wristband employs a technique called surface electromyography (sEMG), which detects electrical signals generated by muscle activity to interpret user movements.
The goal of this wristband is to provide less invasive tools to interact with computers for people with motor disabilities.
Even people with complete hand paralysis still exhibit some muscle activity, allowing the device to interpret their intended actions.
Meta's wristband could be used immediately without surgical intervention, and its use of sEMG signals means it operates at a higher frequency than EEG.
