IBM uses AI limb tracking to score U.S. Open tennis serves for fans

IBM has introduced a new "serve quality" feature at the U.S. Open tennis tournament, utilizing limb-tracking technology powered by AI. This feature analyzes over 20 points on a player's body during serves, processing the data through IBM's watsonx to generate a score out of 100. While limb tracking has been used in other sports, this marks its first application for fan engagement in a Grand Slam tennis event, with the app expected to provide millions of serve quality insights by the tournament's end.
