Bringing tennis to the information age through recordable statistics and identifiable metrics seems to be the next frontier in the sport.
While the game is steeped in tradition, tennis was actually one of the first sports to embrace technology. The not too far distant 2007 Australian Open was the first grand-slam tournament to implement Hawk-Eye in challenges to line calls.
The system works via six or seven high-performance cameras, normally positioned on the underside of the stadium roof, which track the ball from different angles. The video from the cameras is triangulated and combined to create a three-dimensional representation of the trajectory of the ball. Each tennis player is allowed 2 incorrect challenges per set and one additional challenge should a tiebreaker be played. The original system was complicated and cost over $3,000. It costs even more now!

Luckily for us, technology has progressed since then, and has become accessible not only to professional players but also to aspiring amateurs and hobbyists. If you hear people banging on about “the internet of things” and are not quite sure what this is about, it is referring to the future where everything around us will be connected. Including sports.
The tennis technology landscape is already exploding with new and exciting technology. This is our overview of gadgets and wearables that are changing the face of the game.
Data collecting sensors
First and foremost we have data collecting devices. Babolat was the first to enter this market with its Babolat Pure Drive racket. It was quickly followed by the Sony Tennis Sensor, Zepp Tennis Swing Analyzer and more recently the Qlipp tennis sensor.
While Zepp and Sony place their sensors on the butt of the racquet, Babolat‘s sensor is built into the grip. Qlipp, on the other hand, sits on your strings and also functions as a vibration dampener. Then there are those like the Babolat Pop and its big brother Babolat and PIQ, which sit on your wrist and collect information.

All of these gadgets focus on gathering information on technique and dish out a plethora of statistics. The accuracy of this data varies, but does that really matter? The goal of these sensors is to improve your game over time. As long as you are consistently using the same device, you are comparing like with like. Which means your trends over time will show whether you are improving or not.
Smart Court systems such as Playsight and Mojjo have already been installed at a few hundred venues across the US and Europe. These are systems that involve a number of permanently fixed cameras that record everything that happens during play. While less accurate than Hawk-Eye, they are precise enough to check lines and come at a much lower price.
There are more exciting developments under way. For example, a Swiss startup called Technis has perfected an entirely tactile surface to make tennis courts interactive. The technology is directly integrated into the surface of synthetic and resin courts. Every single movement is detected, from the bounces of the ball to the position of the players on the court. The information is displayed in real time on a screen on the edge of the court. While the system is still in the design stage, we can expect to see real-world implementation in the not too distant future.
Even more exciting is a gadget called In/Out. The $200 GoPro like device can be fastened to any tennis net post in less than a minute to detect in real-time which side of the line the ball lands. It does this thanks to the same algorithms that provide line-detection for self driving cars. You essentially get your own personal ‘Hawkeye’ system.
The first unit has now been built and has exited the factory line. This means the hardware is complete and is ready for ‘mass’ production and the late-summer release date. We can’t wait!
Match video analysis is no longer accessible only to professional players. A number of services have popped up, such as Tennis Analytics, that allow you to send raw video footage of your match for analysis. You get back an index video/summary of the match, that allows you to search for any moment in the match. You also receive a professional match report (serve %, aces, double faults, return %, winners, errors, differential for both you and your opponent). While the service is accessible to the recreational player, at over $500 for 10 hours of video, you would really need to be passionate about your game to subscribe!
It is inevitable though that the price of these services will come down over time. While you are waiting, why not video your tennis session with your smartphone, and with the help of the Sony or Qlipp tennis sensors, overlay your metrics on top of the video. These are a great tools to help you find out what you’re doing great and what you need to change.
Tennis apps and online tools
Finally, we have the tennis apps and online tools. Companies such as Global Tennis Network, Sportlyzer, and Coachanize are creating a wide variety of software platforms. Some are predominantly aimed at the recreational player and offer a community where you can find opponents, organize ladders or even book courts. Others are aimed more for clubs/coaches and provide a convenient avenue for client management.
We are very excited where this technology will lead us in the coming years. If this is only the beginning, we can’t wait to see what the future holds in store.
