The Game Changer

Uncovering an Entirely New Set of Data

Traditionally, in order to assess an athlete's mechanics and endurance, coaches have relied on player feedback and instinct. A demanding athletic test, a tennis match can last for several hours and require an athlete to run anywhere from one to six miles back and forth on a court. To better understand and quantify fatigue and energy, IBM has uncovered a new data set called the Energy System, which is comprised of two components – Physiological Load and Mechanical Intensity – that evaluate the total work of the athlete to measure his or her physical performance over a period of time:

• Physiological Load is a measure of the player's physical exertion and overall work done in a match, looking at an athlete's height, body weight, average speed and distance to move from one side of the court to another at various speeds.
• Mechanical Intensity is the cumulative weighted acceleration and deceleration throughout the match that gauges the physical demand on a player's body.

Energy System metrics are combined with traditional tennis statistics and match video in the Coach Advisor portal for coaches to review, point-by-point. Using this tool, coaches can quickly identify key moments in matches and understand the relationship between physical exertion and player performance.

"The USTA is dedicated to developing the next generation of world-class American tennis players, and Coach Advisor offers our coaches access to all-new data to drive performance," said Martin Blackman, General Manager, USTA Player Development. "We are excited to continue our work with IBM to pair analytics with our coaching expertise, and believe IBM Coach Advisor will give us a competitive advantage to help change the paradigm of tennis coaching and development in the U.S."

Coach Advisor also relies on IBM AI to automate match video capture. Analyzing match video has traditionally been a time consuming, days-long, manual process for the USTA staff. Artificial intelligence trained to detect the sounds of ball strikes, umpire calls, crowd noise or even the sound of sneakers on the court, determines the start of a point, and then indexes every point in a match. This enables coaches to view an entire match soon after it is completed, drill down into critical moments in a game, and save time by not manually processing video. Coach Advisor augments a coach's expertise with data analysis to help the USTA team operate more efficiently and focus on supporting players.

Coach Advisor is currently in its initial phase with a select group of players and their coaches and is planned to be rolled out over time to the broader population of American players and coaches.

Enhancing the Fan Experience at the 2019 US Open

In addition to changing the game for professional tennis coaches at the 2019 US Open, IBM will continue to evolve the digital experience for the millions of fans who follow the tournament, as well as those who visit the Billie Jean King National Tennis Center.

The USTA has also adopted a hybrid cloud strategy that enables IBM to take the tremendous amount of tennis data, scores, stats, sights and sounds, and serve up unique and enhanced experiences both digitally and onsite, using a mix of public cloud, private cloud and on-premises systems. Designed by IBM iX, the global business design arm of IBM Services and one of the world's largest digital agencies, enhancements for 2019 include:

• IBM AI Highlights: IBM will again work with the USTA on a suite of AI-powered solutions on the IBM Cloud to analyze matches and deliver AI Highlights shortly after key moments are played. AI Highlights processes hundreds of hours of live video from the tournament, saving the USTA editorial team time and simplifying the video editing process for the USTA and its broadcast partners. This year, AI Highlights are enhanced with Acoustic Insights to help improve sound analysis and recognize when the ball has been struck, allowing a tighter cropping of highlight clips. Using IBM Watson Open Scale, Watson can also now recognize levels of noise and excitement levels of players, allowing it to remove bias when searching for highlights from players with a particularly popular following or those who are particularly animated on court.
• IBM SlamTracker: Fans of SlamTracker will again see scores, statistics and analysis of matches come to life in real time, but now with an enhanced experience. By combining the momentum and live tabs into a single experience, fans will have an improved and streamlined way to follow match analysis with tournament highlights, real-time updates and point-by-point commentary.
• IBM Experience: Located at the Arthur Ashe Stadium, the IBM Experience brings three dimensions of IBM Watson to life for fans, demonstrating how Watson utilizes visual recognition, sound analysis, and natural language understanding to produce AI-generated highlights. In this interactive environment, guests can experience "Watson in Action," create their own AI Highlight, as well as check out the latest AI Highlights for all live show court matches.
