EYES in the back of your head - you know you want them. And soon you may get your wish, simply by slipping on a headset that gives you a 360-degree field of vision. Called FlyVIZ, the system was designed by Jérôme Ardouin and colleagues at the Grande École d’Ingenieurs Paris-Laval in France. It captures images from every direction around the wearer, then transforms them into something our measly human vision system can comprehend.
