Everyday actions like picking up a mug need a quiet sense of touch and finger position. People with prosthetic hands can lose that sense and must control each finger, so actions become slow and tiring.
A research team added proximity and pressure sensors to a commercial prosthetic and trained an artificial neural network on grasping postures. When the AI worked with users, grips were more secure and more precise. Participants could do many daily tasks without long training and felt less mental effort.
