We propose “MetaLimbs” is a prototype exploring a research question “How we can edit or design our body?”. The system is constructed by robotic arms/hands which are mounted on a user and motion tracking which uses socks type sensor device and optical motion trackers, it can modulate from user’s legs/feet movement and posture to the motion of robotic arms/hands. User’s body perception and schema will be changed or augmented by multiple limb interactions.
