An experimental helmet from Toshiba gives its wearer the visual experience of being someplace else. Inside the headgear from the Japanese electronics maker, a 40-centimeter (16-inch) screen can show a vista that is synched with the wearer’s head movements, giving the illusion of actually being there. The 3 kilogram (6 pound) helmet–squared off in the back and rounded, bubble-like, in the front–has infrared sensors at the top that detect which way the wearer’s head is moving. The projector in the back of the helmet shows images corresponding to the head movements on the screen inside the helmet, giving the wearer an illusion of immediacy and realness.
