00:01Introducing Wingfield, an AI-supported robot designed to help tennis players improve their game.

00:07The system was developed by former pro tennis player Jan Brunken and his team.

00:12Here's how it works. Two high-speed cameras observe the court.

00:16They recognize the ball's trajectory and speed as well as players' movements.

00:20The cameras collect data on technique and gameplay.

00:24It's like an assistant for tennis coaches. It handles data processing and analysis.

00:32The coach can then focus on improving something specific.

00:36Wingfield shows a player's strengths and where they can improve.

00:40And it's already in action, installed on hundreds of tennis courts across Germany.

00:45Sometimes there are things I overlook. It's a good aid.
