About
Summary Stanford researchers have developed a patented, wearable, haptic feedback device that provides position and velocity information on the limbs and torso by imparting rotational skin stretch. The motions and sensations produced are analogous to those obtained by placing two fingers against the skin and rotating them together. With brief training, users are able to use skin stretch to gain a sense of motion of their limbs when such feedback is otherwise missing or deficient. Applications for this device include motion training for sports or physical therapy and proprioceptive feedback for enhanced control of prosthetics.
