A research team at the University of California has developed a technology that decodes brain signals from paralyzed patients to express speech and gestures. This involves measuring brain signals through an electrode array implanted on the surface of the brain and converting them into the speech and movements of a virtual avatar. The research team conducted experiments on three paralyzed patients, and two participants were able to simultaneously decode speech and gestures in real-time and control a full-body avatar. This technology is expected to help paralyzed patients communicate more naturally and richly. However, it is currently limited to small-scale experiments with a limited vocabulary and gestures, and further research is needed.
