TL;DR
"In this paper we have shown that an “IVR arm ownership illusion” exists and that it can be tested for and measured using a protocol derived directly from those described in the literature on the rubber hand illusion. The evidence from our experiment by no means proves that the IVR arm ownership illusion is the same as the rubber hand illusion, but we feel that this paper highlights interesting parallels between the neuroscience-based work and the history of the study of effective IVR."I found this pretty interesting, since the rubber hand experience has shown, that we can feel an artificial limb as our own, even when the "orignal" one, that it "replaces", still exists.
