Today, we look at virtual reality mostly as a means of entertainment -- but the technology introduces some interesting questions. Can virtual experience be used to treat PTSD? Could it be used to create false memories? The idea of VR as a tool for "hacking" the brain seems to be the idea behind Ubisoft's new virtual reality title, Transference. That on its own sounds interesting, but if that's not enough, the title has star power: apparently, the game features Elijah Wood.
