AI-Powered Prosthetic Allows Musician to Play Piano Again

Playing the piano requires complex and dexterous finger movements, controlled by the musician’s brain. After losing his arm, musician Jason Barnes thought he would never play two-handed again—until researchers at Georgia Tech developed a prosthetic arm that allowed him to do so.
It uses a deep neural network trained to sense, through ultrasound, the muscle movements in the arm and predicts which finger the musician wants to move.
