Student demos clever head-tracking

An Australian student has been showing off several accomplished head-tracking demonstrations using videogames.

Using Valve's Source engine, Toben Sko can peer around corners by tilting his head, zoom by moving closer to the screen, rotate the camera by turning his head and produce a gun-sight by posturing as if aiming down the barrel of a gun.

The video can be found on YouTube, noticed first by PushingPlay before being picked up by Joystiq.

His work furthers that of folks like internet star Johnny Lee - now a part of the Xbox Natal team.
