Single brain implant decodes both speech and gestures at once, study shows
Researchers at UC San Francisco tested a surgically implanted 253-electrode array that reads brain activity to simultaneously produce on-screen text and animate a personalized avatar's movements. The system, tested with two participants with severe paralysis, is described as the first brain-computer interface to handle verbal and non-verbal communication together within seconds of intent.
GoKawiil's interpretation of the reporting above, not reported fact.
Previous brain-computer interfaces typically restored only speech or only movement control, limiting how naturally paralyzed users could express themselves. Combining both in one device, even as an early proof of concept, points toward assistive technology that could eventually support fuller, more expressive daily communication.
- A single implant decoded both speech and gestures simultaneously for the first time.
- AI converts neural signals into on-screen text and drives an avatar's movements in near real time.
- Tested in two paralyzed participants using a 253-electrode cortical array; still an early proof of concept.
