Learning new body schema

What happens to the human's perception of her own body when controlling a prosthetic limb? The internal brain representation of the body is referred to as a body schema. It was proposed over a century ago [115] that when people skillfully use tools, the body schema adapts accordingly so that the brain operates as if there is a new, extended body. This results in perceptual assimilation of the tool and hand, which was confirmed from neural signals in [131]. This raises a fascinating question for VR research: What sort of body schema could our brains learn through different visual body representations (avatars) and interaction mechanisms for locomotion and manipulation?
