The out-of-body experience - the feeling that you are “floating” above yourself - has puzzled scientists for years. However, now Dr. Henrik Ehrsson has figured out a way to re-create the sensation by having people look at a 3D video image of the back of their own head while stroking them with a stick. The disorienting sensation made people feel like they were looking at themselves from the location of the camera. This discovery has implications for video game reality, as well as surgery, since someone may be able to remotely control a virtual version of themselves in the operating room.
