High tech hurdle jumping for Lolo Jones

LONDON, England (AP) - The long-limbed red, green and blue stick figure on the computer screen hopped over the orange hurdle and hustled down the lane.

That brightly shaded avatar was a mirror image of hurdler Lolo Jones' movements on the track and just might go a long way in leading her to another color -- gold at the London Games.

Using computer-vision technology and 40 high-speed, motion-capture cameras, computer scientists, along with sports biomechanics and physiologists, have been studying every minute detail of Jones' form in practice as they try to figure out the fastest way to get her over the hurdles.

Jones' technique was captured on film, scrutinized on a video screen and sharpened on the track in a hush-hush program Red Bull dubbed "Project X."
