Using a mannequin and VR goggles and team of scientists have been able to trick the mind of users by using real touch along with a virtual world to first make the users believe they are being touched than they only touch the mannequin and the user thinks it is there own body,

In this case they used a knife to cut the stomach of the mannequin and most users reacted as if it were there own stomachs being cut.  A really great video clip can be found at this link here named Body Swapping Becomes Reality
