MetaArms: Body Remapping Using Feet-Controlled Artificial Arms
summary
A wearable system called MetaArms maps feet motion to two anthropomorphic robotic arms (6–7 DOF each) mounted in an 8 kg backpack, using HTC Vive trackers, a single toe bending sensor and a haptic belt in the DataSocks for closed‑loop feedback. Twelve naïve users achieve a Fitts' throughput of 1.01 bits/s (std 0.39) after short practice and reduce pointing error over four 45‑minute sessions, but performance hits from 400 ms latency and rising foot fatigue.
