UCSF Team Shows Brain Implant Can Decode Speech and Gestures for Avatar Communication

An NIH-funded University of California, San Francisco team reported a brain-computer interface that can decode attempted speech and upper-body gestures at the same time, using a single cortical implant to drive a personalized virtual avatar. The work, published September 14, 2026, frames assistive communication as more than text or synthetic voice: the system is designed to restore some of the body language that is normally part of conversation.
