Engadget points out attention to a third-person hack for the Oculus Rift. The experience can be achieved by mounting a pair (one for each eye) of GoPro cameras mounted to a tall antenna carried in a backpack. It looks pretty cool but there's still some work to be done as the cameras don't respond automatically to head movements just yet. The project is an entry for an Intel competition, it was constructed in just a couple of days.
The cameras don't respond automatically to head movements just yet, so they have to be controlled by means of a small thumb stick, but they nevertheless augment the wearer's 3D vision: By giving him a view of the real world as seen from a couple of feet above his head, he could scan a wider part of the horizon, or safely peer out from a sniper-infested trench (do we still have those?) or simply to enjoy the uncanny feeling of staring down at his own head and neck.
