Gametrak: Dark Wind (PlayStation 2)

Dark Wind allows players to punch and block with their hands, which Gametrak tracks in full 3D. Unlike existing infra-red, tilt or camera-based systems which have tried, and failed to deliver true 3D interaction, Gametrak tracks motion to 1mm of accuracy, in real-time with no time delay, and no processing hit, meaning all of the console's power can be used to deliver great graphics and gameplay.
