Motion Guidance Sleeve: Guiding the Forearm Rotation through External Artificial Muscles
summary
A wearable sleeve uses stepper motors pulling fishing lines and elastic bands to simulate muscles; eight artificial muscles cross the inner and outer forearm and attach near the elbow. Two lab studies show the device reliably cues rotation direction and can steer to a target angle: faster contractions produce faster user responses, longer contractions yield larger rotation angles, and a three-stage tactile cue improves angle precision. Users distinguish contraction versus relaxation and report perceivable pulling guidance.
