Meta unveils noninvasive BCI that turns thoughts into text without surgery, reaches 61 percent accuracy
Meta has unveiled Brain2Qwerty v2, a noninvasive AI-based brain-computer interface that converts brain activity into text without brain surgery. The system uses helmet-shaped magnetoencephalography equipment and an end-to-end model to reconstruct intended sentences, and it fine-tunes a large language model for neural data. Meta said average word accuracy reached 61 percent. Nine volunteers took part, and results and training code were released alongside a paper in Nature Neuroscience.
