IBM launched limb tracking at this year’s U.S. Open – and it’s scoring every tennis player’s serve for fans to see

IBM launched “serve quality” in the U.S. Open app, using camera-based limb tracking processed by WatsonX to score every player’s serve movements for fans. The feature analyzes 20+ points per player and will process about 1.2 billion joints by the end of the 2026 tournament. Fans can now view an after-match serve quality score (and insights) in the app for each singles match, with plans to extend skeletal tracking to more shots and future tournaments.

Why it matters

This marks the first time IBM has launched a limb-tracking feature at a Grand Slam tennis tournament.
