Wimbledon Goes Automated

When you think of tennis, you probably think of Wimbledon, the All England Club’s famous competition that has run for 147 years. Part of that history has always been line judges who call the ball in or out, sometimes to the ire of players and fans alike. But line judges will be no more at Wimbledon. They are moving to ELC or electronic line calling on all courts in both the main draw and the qualifying tournaments, according to [Tumaini Carayol] writing in The Guardian.

Of course, in 2007, the competition started using “Hawk-Eye,” which allows for review and challenges of the calls. ELC has also been used in other venues, such as the US Open, which has also done away with all line judges.

In fact, the only grand slam tournament that isn’t using ELC now is the French Open. There is some concern, however. The increased availability of line judges will cut down on the demand for new line judges at lesser tournaments. However, these jobs are a common pathway for aspiring chair judges to gain experience and exposure.

According to the Bloomberg video below, the system uses cameras and microphones to keep track of the ball’s position. Other reports say there are 18 cameras and, apparently, the system uses a computer-generated voice to call “out,” “fault,” or “foot fault.”

Apparently, there are some downsides, however. Last month at the US Open, play was halted because the remote office of the technicians operating the ELC system had to evacuate due to a fire alarm.

[Lewin Day] thinks tech will ruin sports. He may be right. Of course, we are more likely to play sports on technology.

Wimbledon 2019: IBM’s Slammtracker AI Technology Heralds The Demise Of The Human Player

Whilst we patiently wait for the day that Womble-shaped robots replace human tennis players at Wimbledon, we can admire the IBM powered AI technology that the organisers of the Wimbledon tennis tournament use to enhance the experience for TV and phone viewers.

As can be expected, the technology tracks the ball, analyses player gestures, crowd cheers/booing but can’t yet discern the more subtle player behaviour such as serving an ace or the classic John McEnroe ‘smash your racket on the ground’ stunt. Currently a large number of expert human side kicks are required for recording these facets and manually uploading them into the huge Watson driven analytics system.

Phone apps are possibly the best places to see the results of the IBM Slammtracker system and are perfect for the casual tennis train spotter. It would be interesting to see the intrinsic AI bias at work – whether it can compensate for the greater intensity of the cheer for the more popular celebrities rather than the skill, or fluke shot, of the rank outsider. We also wonder if it will be misogynistic – will it focus on men rather than women in the mixed doubles or the other way round? Will it be racist? Also, when will the umpires be replaced with 100% AI?

Finally, whilst we at Hackaday appreciate the value of sport and exercise and the technology behind the apps, many of us have no time to mindlessly watch a ball go backwards and forwards across our screens, even if it is accompanied by satisfying grunts and the occasional racket-to-ground smash. We’d much rather entertain ourselves with the idea of building the robots that will surely one day make watching human tennis players a thing of the past.
