The Head Cam is a helmet with a snakelike appendage that holds a miniature video camera in front of the wearer's face. The wearer is always in focus and centered in the camera's view while their background goes bouncing and jiggling behind. Perspective can be exaggerated by the extreme wide-angle or fisheye lens necessary to get the entire face in the shot at such close range.
The Head Cam is often seen in reality TV shows like The Mole
and Fear Factor.
Peter Gabriel also used such a camera on his Secret World Live tour for the song "Digging in the Dirt" (you can see it in action on the DVD from this tour).
Similar to the Facecam
, except the Face Cam isn't mounted in a helmet.
