A new virtual reality illusion can trick users’ brains into thinking they inhabit a non-human body — like a bat or a spider.
The VR, built by scientists from Germany’s University of Duisberg-Essen, is a new high-tech twist on the classic rubber hand illusion, according to MIT Technology Review, in which people are fooled into feeling as though an inanimate object is part of their body. In a bizarre twist, there were even cases in which study participants felt more ownership of a virtual animal’s body than a virtual human one, suggesting just how powerful an effect VR can have on the brain.
When the experiment used VR to simulate flying, participants often felt more ownership of a bat’s body than a human’s, according to the research, which was published earlier this month in the preprint server ArXiv.
But they didn’t just feel ownership over an animal’s body when it matched the task at hand. Even when injected into a virtual spider’s body, participants reported just as much a feeling of ownership as they did a human-like avatar, despite having an entirely different skeletal structure than people are used to.
“Our empirical results demonstrate that virtual body ownership is also applicable for nonhumanoids,” reads the research, “and can even outperform human-like avatars in certain cases.”
