"The sensors are accelerometers similar to what's in the Wii," says physicist Andrew Spence, who participated in the work. "Once you synchronize the two, you can determine the relative motion of the man and the horse." The jockeys also wore global-positioning trackers so their speed and position could be followed. "The tracker was in the helmet, where the GPS satellites could...
