@rowancheung: 🫳 MIT engineers have developed an ultrasound wristband that tracks hand movements in real time and wirelessly transmits them to control robots or virtual environments. The device images muscles and tendons in the wrist, while an AI algorithm interprets those images to pinpoint the position of all five fingers across 22 distinct motions. In tests, wearers controlled a robotic hand precisely enough to play piano, and manipulated virtual objects through natural gestures alone. The team, led by Professor Xuanhe Zhao, is now gathering data from wider populations to train humanoid robots in dexterous tasks including surgery.
