AI Wimbledon robot examines player's bodily gestures to decide best bits of tennis

Artificial intelligence will be at play in Wimbledon this year in the form of software that captures player's bodily movements to create replay highlights. IBM's Watson analyses everything from a player's celebratory cheers to their fist pumps through a live video stream to record a clip of that point in the match. Each point is then ranked based on crowd excitement, as well as noises from players, through a microphone placed underneath the umpire's chair. Wimbledon, now in its 49th year, also used the AI system, powered by computing firm IBM, last year. Now, for the first time, IBM Watson has been taught to recognise the strike of a tennis ball on a racket.
