A system that allows for better visibility of the technique and precision of fencers.

Japanese engineers have created a system that tracks the movement of a sword in real time and creates a colorful trail. The developers believe that technology makes fencing more understandable and entertaining.

Previously, it was virtually impossible for an untrained spectator to watch fencing—everything happens too quickly to discern anything.

This system uses AI to track the movement of the sword tip without markers and displays it as dynamic trajectories in real time. This allows one to not only understand what's happening on the screen but also to marvel at the epic nature of the duels.

Similar solutions have existed before, but the technology has now been perfected and is planned for use at all major competitions.
