Hawk-Eye’s vision extends to soccer and beyond
The eyes of these animals were greenapparently a transition color suitable for neither the full light of summer nor the full dark of the true, on-like-Donkey-Kong winter typical of rural Norway. In another experiment, the researchers removed the golden tapetum lucidum of summer reindeer and laid them out for observation. They then applied pressure with a small weight and watched the samples immediately turn deep blue. When the weight was removed, the blue ebbed, and the gold slowly returnedthough the eye slabs lay disembodied on a slide.

The concept has been used for several years in sports such as rugby union and American football; Hawk-Eye aims to reduce the reliance on TV broadcast output to come up with quicker and clearer answers. Its Officiating Replay System allows an extra referee to quickly monitor multiple TV feeds from the broadcaster before they are aired, to review contentious calls to, say, award a penalty kick or disallow a goal for offside.
