This handout picture taken in an unknown location in 2016 and obtained on May 13, 2016 from French public research centre INRIA (Institut national de recherche en informatique et en automatique - National Digital and Automation Research Institute) shows a man using the experimental virtual reality platform "Six Fingers", developped by INRIA's Hybrid and Mimetic teams, which allows the user to observe a sixth finger on their own hand. Using a virtual reality headset and a computer, the system generates an extra finger during the observation of the hand, to study how that hand is assimilated by the user as if it were their own. / AFP PHOTO / INRIA / JC Moschetti / RESTRICTED TO EDITORIAL USE - MANDATORY CREDIT "AFP PHOTO / INRIA / JC MOSCHETTI" - NO MARKETING - NO ADVERTISING CAMPAIGNS - DISTRIBUTED AS A SERVICE TO CLIENTS JC MOSCHETTI/AFP/Getty Images
