From Aidan Karley
Laura Spinney writes about perception changes while wearing various types of inverting goggles (11 October, p 42). I wonder how experiments in this area will change as high-definition virtual-reality headsets like the Oculus Rift become more widely available.
For example, “perception” could be switched in an instant, without framing cues; or one eye could get 10 degrees of rotation more than the other.
