If you could be anybody in the world, who would it be? Your neighbouror a super star? A few people have experienced what it might be like to stepinto the skin of another person, thanks to an unusual virtual reality device.Rikke Wahl, an actress, model and artist, was one of the participants in a bodyswapping experiment at the Be Another lab, a project developed by a group ofartists based in Barcelona. She swapped with her partner, an actor, using amachine called The Machine to Be Another and temporarily became a man. "AsI looked down, I saw my whole body as a man, dressed in my partner'spants," she said. "That's the picture I remember best."

The set-up is relatively simple.Both users wear a virtual reality headset with a camera on the top. The videofrom each camera is sent to the other person, so what you see is the exact viewof your partner. If she moves her arm, you see it. If you move your arm, shesees it.

To get used to seeing anotherperson's body without actually having control of it, participants start byraising their arms and legs very slowly, so that the other can follow along.Eventually, this kind of slow synchronised（同步的）movement becomes comfortable, and participants reallystart to feel as though they are living in another person's body.

Using such technology promises toalter people's behaviour afterwards-potentially for the better. Studies haveshown that virtual reality can be effective in fighting racism-the bias thathumans have against those who don't look or sound like them. Researchers at theUniversity of Barcelona gave people a questionnaire called the ImplicitAssociation Test, which measures the strength of people's associations between,for instance, black people and adjectives such as good, bad, athletic orawkward. Then they asked them to control the body of a dark skinned digitalcharacter using virtual reality glasses, before taking the test again. Thistime, the participants' bias scores were lower. The idea is that once you've"put yourself in another’s shoes" you're less likely to think ill ofthem, because your brain has internalised the feeling of being that person.

The creators of The Machine to BeAnother hope to achieve a similar result. "At the end of body swapping,people feel like holding each other in their arms," says Arthur Pointeau,a programmer with the project. "It's a really nice way to have this kindof experience. I would really, really recommend it to everyone."
