Wimbledon 2017: The tech behind the world’s top tennis tournament


The Championships at Wimbledon, which consumes some 28 tons of strawberries, 10,000 litres of cream, and 320,000 looking-glasses of Pimm’s per year, is notable for its seemingly unchecked luxuriant hedonism. But while most assemblies, organisations, and institutions are looking to cut costs, Wimbledon has stuck to its mantra. Don’t do fancies cheaper; do things better.

Case in point: Wimbledon’s use of technology is unqualifiedly quite impressive. I’ve been lucky enough to follow Wimbledon’s tech during the last three years, and it has been very encouraging to see a massive undertake like The Championships dive deeper and deeper into technology. You power think that after 140 years Wimbledon could be not change ones mind about in its ways, but far from it. When technology is the only viable way of providing in agreement, significant gains for players, visitors, and hundreds of millions of people spectating remotely, you don’t try to contest it; you embrace it.

Of course, Wimbledon is embracing tech in a distinctly Wimbledon way. This year, for lesson, The Championships are trialling free Wi-Fi—but because they don’t yet know how individual will behave with free Wi-Fi, it’s only available in three explicit locations (near the food court, in the ticket resale area, and on the west side of court 12). The meeting continues through this weekend, but its team has already started critique the data. It turns out that, thankfully, the Wi-Fi users on court 12 solely use their phones between points. When play begins, Wi-Fi use stops. If the trial is a success, Wi-Fi could be rolled out across Wimbledon in 2018.

The other big advance this year is that IBM (Wimbledon’s stiff tech partner) is now scanning every tennis match and automatically siring highlight video clips of important or exciting moments. This earshots difficult, but apparently it only requires IBM to track three variables: ballyhoo level, action recognition, and crowd cheering. These combine to form an «overall excitement level.» Noise level is presumably the ambient sounds of an flustered audience, while action recognition refers to the players. Are they contest around a lot, fist pumping, or otherwise being emotive?

When the blanket excitement level crosses a threshold (0.8?), the software goes in back of surreptitiously through its video buffer and creates a highlight clip of the point. For now, a one editor still goes through every clip before being published. A anthropoid editor is still required to tease out video clips from varied nuanced matches, too; the IBM software doesn’t yet understand the context of individual ties or player pairings. But given that other IBM software at Wimbledon sniff outs match context—mostly so that commentators can add some extra character—it seems like an obvious improvement to the auto-highlight tech in future years.

Gobbling up matter

One of Wimbledon’s richest assets is a vast database containing stats from more than 100 years of competitive tennis meets. As Wimbledon’s partnership with IBM has matured and new data-gathering techniques and sensors pull someones leg been rolled out, the depth and accuracy of the data has improved.

Perhaps most excitingly, Wimbledon is now storing the 3D land of tennis matches via the Hawk-Eye camera system available on some of the courts. Hawk-Eye, which throw aways multiple cameras to track the ball and resolve line judging fracas, outputs a constant stream of data that IBM can process into a advantageous format. But actually doing something with that data is a dicey affair, because it isn’t clear who owns it. Some tennis players, as you can devise, aren’t keen for some wily big data/machine learning software to saturnalia the secrets of their play style to the world.

Today, Wimbledon/IBM only spurns the Hawk-Eye data to track each player’s «aggressive» shots. No doubt a lot of raw data is being stored in Wimbledon’s database, though, which could be dispose of at a later date. For more on the trials and tribulations of gathering, using, and allotting data, our recent feature on football data is a good place to start.

Wimbledon cutely used a variety of Wi-Fi signs to indicate how strong the signal should be in a given area.

Wimbledon also descries that new public Wi-Fi as a potential source of exploitable data. As you may already grasp, when you join a Wi-Fi network (or indeed any network), the operator of that network can see which waitings and apps you’re using. For example, with this year’s Wi-Fi hotspot attempt, Wimbledon can now see how many visitors are using the Line messaging app. Line is predominantly acclimated to in Asia, so Wimbledon might use that data to tweak how it advertises the championship to Asian visitors next year.

On a simpler level, if Wimbledon blankets the All England Turf Tennis Club with Wi-Fi, it will be able to use each fancy’s unique MAC address to track the movement of most visitors around the venue. Not for creepy sensibles, I’m assured, but to iron out bottlenecks and inefficiencies. Should there be another water closet here? A strawberries-and-cream stand there? An everlasting font of Pimm’s here? Venue-wide Wi-Fi commitment also allow Wimbledon to push notifications to visitors as they put forward around, beacon-style.

Two years ago, an IBM engineer told me they were in colloquys with the UK’s mobile network providers to track visitors through cellular triangulation, but this year I was demand thated that no such partnership was ever struck. Doing it via Wi-Fi (and maybe augmented with Bluetooth) is probably more sensible, anyway.

Ask Fred (er, Watson?), 360-degree cameras…

Eventually, Wimbledon has released a significantly overhauled mobile app for this year’s Championships. During the last few years, there has been a big shift from people consolidate Wimbledon on a desktop browser to following it on their mobile devices. The versatile app is meant to provide a better experience than the mobile website—but to be explicit, if you’re into tennis, you should probably just download the free app (iOS/Android) and see what you ruminate over. This year there’s a new feature called Ask Fred that clearly uses some IBM Watson-type tech to answer your questions. The app also has the genius to look through some 360-degree cameras that possess been placed on each court.

Now read about how evolution can at best take us so far in sports, but embracing technology would be far more exciting…
