Fencing is a sport that has been quite forward looking in terms of technology for adjudication, including the introduction of instant replays for video refereeing. However today’s manual systems have trouble tracking two rapidly moving athletes. The components of Moderator are a technology which tracks a pair of athletes’ movements along the fencing piste and a camera tracking algorithm which moves the camera according to the athletes’ positions. Storage, replay capabilities and performance analytics sit behind this system to provide a robust commercial offering for video referees, athletes and fencing clubs. Our patent application has been approved nationally and is pending international confirmation, while we have on-boarded the Italian Fencing Federation as a project partner. It was initially designed for the sport of fencing, but has the potential to apply in a number of other sports such as Kendo, Taekwondo, Judo and Karate. Moderator will make the adjudication of highest level combative sports fairer and more transparent, with benefits for both athletes and spectators, while also providing valuable performance analytics.
