Tennis And Data: Methods Used To Collect Information And How Much Each One Costs!

The latest instalment in our series of articles on data in tennis. Today we are going to talk about systems to gather data, from the most expensive (such as Hawk-eye) to the up-and-comers like FoxTenn.

2. Training Assistants and technical-strategic tutoring

This category of applications includes products intended for tennis clubs, academies and, in general, for structures where they can be useful for coaches to use tracking technology to assist tennis players during and after training, in order to monitor their progress. Technologies are mostly permanently installed in the facilities. In this category we find the following products: AccuTennis, Mojjo, Playsight, Wingfield and Zenniz. We must remember that Hawk-Eye and FoxTenn have also developed solutions for tutoring (coaching) and training in tennis academies as well. 

 

The features common to these solutions are the following: 

  • They mainly use cameras and computer vision to monitor the players and the ball
  • They have a touch screen interface mounted in a stand to allow users to log in and start the game or the training session 
  • The systems capture videos of each match or session, allowing users to review a shot even from different angles
  • Generally, these systems are networked, so that all videos and data are uploaded to the cloud.

They are provided with an application which allows users to review match and training statistics, share them with their coach and on social media.

AccuTennis

Cost: $5 for each player who uses it (revenue sharing model) 

This US start-up, based in Newtown, Pennsylvania, was founded between late 2016 and early 2017. The key people are Adam Sher (CEO), Dave Kliebhan (CTO) and Andy Hatstat (COO). The AccuTennis system is equipped with 22 cameras installed around each court to monitor all training activities, speakers to provide audible feedback during the game or the training, and a side-mounted double-sided LED screen that displays the score or provides visual feedback of the session. A tablet accompanies every AccuTennis court to allow coaches and users to log in and start their session. The system includes tools to create exercises and individual training programs for their players

Coaches can track their players’ progress regardless of whether they have achieved the goals set for those sessions and identify where they need to work harder. In addition to training sessions, the system also performs game monitoring, meaning line calling, score monitoring, statistic processing and videos acquisition. After the game, AccuTennis generates other numbers represented in charts and heat maps for further analysis while videos are categorised by shots and game type so that players can review specific segments of their game, take notes and replay at different speeds. At the moment, it seems that the solution is valid primarily for indoor courts and it is only available in the United States.

Mojjo

Costs: € 3000 for the installation, annual license between € 1500 and € 4000

Mojjo is a French company co-founded by engineer Emmanuel Witvoet in 2013, which includes Fabrice Santoro in the dual role of investor and testimonial. Their camera-based system is available in two versions: a Premium one with two HD cameras (one at the centre of the court and one in the back) and a touchscreen kiosk to allow users to interact with the system, and a “lite” version with a single HD video camera installed in the rear. Both versions also have outdoor options, which is essentially a roof structure that protects the kiosk from atmospheric elements. 

In addition to most of the previously mentioned mentoring, training and game monitoring features, there are some unique characteristics in the product.  One of these is the ability for a user to deploy their mobile phone as an additional camera to capture videos while it is synchronized with the main system. By using the Mojjo Remote application, the smartphone can be placed anywhere on the court providing a personalized perspective over the central or rear view.

Another interesting feature is their live streaming of games on YouTube or Facebook Live.

The solution turns out to be quite practical and intuitive. The next goal of the French company is to upgrade the product for media and sponsoring companies.

PlaySight

Costs: $ 10-12,500 + monthly fee for other services

PlaySight is an Israeli company founded in 2010. Similar to FlightScope, the implemented technological solution has its roots in military applications

Although now it is used in many different sports, the system based on video cameras, computer vision and artificial intelligence algorithms was initially conceived to assist tennis players in order to help them improve their game by using advanced technology. Currently, the “Smart Court Pro” (high performance) can have up to 10 cameras, all synchronized for a multi-angle viewing experience, usable both in real time and after the game. Every court has a kiosk that allows users to register, create their own drills and start tracking their training or playing sessions.

Options are available for various audio feedback and users/coaches can pause at any time to review the videos or check the statistics collected until then. After a match or a training session, users can still access all their data on the mobile app. The product includes in-depth data collection and analysis. Other interesting features of the PlaySight application include: 1) the ability for users to create their own videos with their synthetic content and share them with coaches, friends or on social media; 2) the upload of other videos if they have not been recorded on a court equipped with PlaySight, as well as the possibility of exploiting the analysis with the app features; 3) access to live streaming and “on demand” events. 

The USTA is collaborating with PlaySight on its National Campus in Orlando, Florida, in order to be provided with technologically advanced tools on its playing courts. Playsight is available in many locations in the United States, Europe and parts of Asia. 

Wingfield

Costs: from 3600 to 4500 euros per year (minimum three years contract)

Wingfield is a start-up based in Hannover, Germany, founded in October 2017, which has developed a solution also based on video cameras, although it is slightly different from those we have talked about until now, given the fact that it is a compact system designated to integrate into the tennis court. The Wingfield Box replaces one of the two net posts, and has a touch screen as well as two high-speed cameras that point to each side of the court. In addition, it sports an IP camera that can be installed anywhere around the court, capturing a complete view of each session. It has most of the mentoring, training, and monitoring functions that have been mentioned earlier, including video analysis, shot tracking, performance measurements, data analysis and more. 

However, a couple of unique features of their system stand out and include: 1) a simplified way for players to access their training session using the app with customed QR code, and 2) Stroke Scores which provides users with a unique metric for understanding quality of different shots and keep track of progress over time.

Zenniz

Costs: 8900 euros or 260 euros per month for four years

Zenniz is another start-up that has developed a built-in camera in the net posts and it is designed to be permanently installed on a tennis court. The company was founded in 2018 and it is based in Helsinki, Finland. However, it appears that the product is not completed yet, as their website suggests it will be available from 2021.  At first glance, it looks similar to Wingfield, as it consists of a “box” (or kiosk) that is installed in place of one of the net posts. The kiosk has a touch screen at the top with two cameras that capture activities on each side of the court. There is also a reference video camera that provides a complete view of the court. The few key differences compared to Wingfield are firstly that the kiosk is equipped with two LED screens, facing each side of the court, that provide real-time score trends and key statistics, and secondly that the system also made up of 30 sonar sensors, positioned around the court, which are able to provide ball tracking accuracy up to 1cm with video cameras.

PTPA Outline Vision After Appointing Executive Director And Advisory Board

The PTPA has announced a new executive director and advisory board.

The Professional Tennis Players Association has outlined their vision for the future after appointing an advisory board and an executive director.

 

Vasek Pospisil made the announcement last night as he and Novak Djokovic look to secure a legitimate players voice at the tennis political table.

In the main core of the statement they announced the make-up of the PTPA’s backroom board, “PTPA co-founders Vasek Pospisil and Novak Djokovic have named Adam Larry executive director, enlisted Carrie Gerlach Cecil to lead Brand and Communications and appointed Bill Ackman, Michael Hirshfeld, Rebecca Macdonald, Katarina Pijetlovic and Anton Rabie to its Advisory Board,” the statement read.

“Created by the players for the players, the PTPA is an integrated association for professional tennis players. The PTPA movement is uniting and mobilizing tennis players in order to create transparency and fairness throughout decision-making in professional tennis.”

The move is an interesting one as up until now it was a mystery as to what the PTPA’s strategy was and who was involved so far with there being no idea from the ATP or WTA’s side what the PTPA was trying to achieve.

Now there is an advisory board there may be sharp movement and progress made into how the PTPA can secure more player-related decisions in Tennis and ensure that there is a level playing-field in terms of decisions affecting the players.

In the statement Vasek Pospisil, Novak Djokovic and new executive director Adam Larry all gave strong hints about the PTPA’s future vision as they look to challenge the establishment in providing change for tennis.

“With the establishment of our advisory board, our branding and communications team and the appointment of Adam Larry as executive director, we have taken one step closer to toward our goal of facilitating a fair and sustainable competitive environment for tennis players today, and for generations to come,” Pospisil said.

“We are working toward growth to help all players, not just the top 100, to make sustainable livelihoods and have their rights protected on and off the court. From top to bottom, we must use our collective voices to help players today and tomorrow,” stated world number one Novak Djokovic.

“The PTPA wants to work with all of the tennis governing bodies to inspire collective reform to better the sport,” new executive director Adam Larry claimed.

What comes next for the PTPA nobody knows but this new board means that business is expected to pick up very quickly in the latest twist in the political tennis game.

Novak Djokovic Confirmed For Olympics But Del Potro Pulls Out After Medical Advice

The Serbian will be bidding to win gold in Tokyo later this year for the first time in his career.

This year’s Olympic tennis tournament has been given a boost after officials confirmed world No.1 Novak Djokovic will be playing at the Games.

 

The 19-time Grand Slam champion had been contemplating whether to play at the event or not amid ongoing COVID-19 conditions. Djokovic previously said he would reconsider travelling to Tokyo if fans weren’t allowed to attend. Since that comment, organisers have given the green light for up to 10,000 domestic fans to attend Olympic venues. Although foreign fans are banned from attending this year due to the pandemic.

Amid questions over Djokovic’s participation, the Serbian Tennis Federation has told Sportski Zurnal that he has pledged to play. It will be the fourth time the 34-year-old has represented his country in the Olympics. So far in his career, Djokovic has only won one medal which was bronze back in 2008. He also finished fourth in 2012.

“Novak has confirmed his desire to participate in the Olympic Games and we have already sent a list with his name on it to the Olympic Committee of Serbia. It will be forwarded from there,” the Tennis federation told Sportski Zurnal.

As it currently stands Djokovic is on course to achieve the calendar ‘golden slam.’ A rare achievement where a player wins all four Grand Slam titles, as well as the Olympics, within the same year. In singles competition the only person to have ever achieved this was Stefi Graf back in 1988.

“Everything is possible, and I did put myself in a good position to go for the Golden Slam,” Djokovic said after winning the French Open
“But, you know, I was in this position in 2016 as well. It ended up in a third-round loss in Wimbledon. This year we have only two weeks between the first round of Wimbledon and the finals here, which is not ideal because you go from really two completely different surfaces, trying to make that transition as smooth as possible, as quickly and efficiently as possible.
“So obviously I will enjoy this win and then think about Wimbledon in a few days’ time. I don’t have an issue to say that I’m going for the title in Wimbledon. Of course, I am.”

Del Potro’s comeback delayed again

There is less positive news for Juan Martin del Potro, who was the player who beat Djokovic to win a bronze medal back in 2012. The Argentine hasn’t played a competitive match on the Tour since June 2019 due to a troublesome knee injury. Back in March the former US Open champion said playing at the Olympics again was motivating him during his rehabilitation.

However, since then progress has been slower than what Del Potro would have liked. As a result, he has been advised not to play in the event and continue his recovery.

Delpo won’t be able to play the Olympics Games. The knee rehab is going well according to the doctor’s plan but he suggested Juan Martin to go on with his rehab process and training, and skip Tokyo 2020,” a statement from Del Potro’s communication team reads.

Since 2010, the former world No.3 and two-time Olympic medallist has undergone eight surgeries.One on his right wrist, three on his left wrist and four on his knee. He has won a total of 22 ATP titles so far in his career.

The Olympic Tennis event will start on July 24th at the Ariake Coliseum.

Victoria Azarenka continued her momentum towards Wimbledon.

Victoria Azarenka (@24NewsHD - Twitter)

Victoria Azarenka and Amanda Anisimova both cruised into the second round as they prepare for Wimbledon.

 

Starting with two time grand slam champion Victoria Azarenka who enters this week after winning the doubles title with Aryna Sabalenka in Berlin.

Azarenka continued her momentum with a 7-5 6-0 win over compatriot Yuliya Hatouka.

The world number 14 struggled in rainy conditions in Germany in the first set as she was broken three times in the first set.

It was a tough start from Azarenka who couldn’t consistently blast past the world number 271.

In the end Azarenka saved some break points and broke in her following two return games to seal the opening set in 53 minutes.

However the second set was much easier as she didn’t concede a single break point and won all six games.

Azarenka will now play Alize Cornet in the second round.

Meanwhile 19 year-old Amanda Anisimova is looking for a good grass court season after crashing down to 81st in the world.

The American sealed a 6-1 7-5 win over German veteran Andrea Petkovic as she moved into the last eight.

Anisimova produced a high-quality first set as she stormed into a 4-0 lead in the opening set.

After sealing the opening set in 24 minutes, Anisimova continued the momentum by breaking in the opening game of the second set.

However Petkovic has shown good performances on a grass court in the past and she remained resilient to break back for 4-4.

Despite that setback, the American broke in the eleventh game and closed out the match to love.

Anisimova will play Angelique Kerber or Anna Blinkova next.

In other results Katerina Siniakova edged past Jessica Pegula 6-3 5-7 6-4 and will meet Laura Siegemund in the quarter-finals.

Siegemund booked her place in the last eight with a 6-2 6-2 win over Tamara Korpatsch.
