call results together with a live scoreboard can be projected to onsite display panels or streamed
to the internet during a match.

eyes3 aims to provide tennis tournament organizers a high quality electronic line call system to
promote fair play and increase spectators engagement for their tournaments. Tennis clubs, local ,
regional and national events organizers are our targets.

• 2 – 8 iphones as cameras
• 1 iphone or ipad or apple watch as the control device
• Internet connection via cellular or wifi
• Accessories for mounting the phone such as phone holder and tripods

eyes3 leverages multiple phones automatically to deliver accurate and reliable results. More
cameras also ensure more angles are covered and less chance for the ball to be occluded by the
players.
We recommend using 2 cameras (1 on each side) for a casual match. For more serious
tournament qualifying rounds matches, 4 cameras are recommended (2 on each sides placed
near the net). 6-8 cameras (3 or 4 on each side) can be used for the main draws for maximum
accuracy.

While we recommend using multiple camera for line call results for high quality line call results,
there are certain scenarios where using just one camera suffices. For example, if you are
practicing serves and wanted to know the speed and consistency of your shots. You can just one
camera positioned near the net and face the target side of the court. eyes3 will be able to provide
a range of information on your serves.
eyes3 has a built in Game mode where players can host a serving challenge with a built in
leaderboard. You can set up one camera for Game mode.

eyes3 works with iphone SE second generation or above. Use newer models such as iphone12
or iphone13 if you require faster response time.

eyes3 has been successfully deployed on large stadium center courts, as well public courts.
eyes3 works equally well in indoor and outdoor courts. The colors of the court does not matter as
long as the lines are visible.

eyes3 works any court surfaces including clay and grass courts. Our AI calibration system is able
to calibrate any court surfaces in matter of seconds. The only requirement is that the court
surface is flat and well maintained, lines are visible and the court dimension adheres to
international standards.

eyes3 uses video to perform its function and as a result lighting does have an impact on its
performance. eyes3 may not work well in conditions at night with older lighting systems. In
general, the newer generation of LED lighting systems should work well with eyes3.

Depending on the number of phones required, the typical setup takes about 5-10 minutes to
mount the phones on tripods around a court. Once the phones are physically mounted, eyes3
can automatically calibrate a court via a single button press.

eyes3 can perform significantly better than an umpire with a full compliment of line judges at a
professional match. eyes3 has been deployed at various national level tournaments in Asia with
excellent results.

eyes3 patented technology and our AI computer vision algorithms calculates ball trajectory in real
time based on the videos recorded using multiple mobile phones. Knowing the entire trajectory of
the ball allows eyes3 to accurately determine the ball’s landing location.

By signing into the eyes3 App using the same account, eyes3 automatically coordinates the line
call and analytics across all the phones once the phones are set up. The combined results are
then delivered to the users via the control device.

eyes3 splits its processing between the iphone and cloud servers internally during execution. As
a result, eyes3 requires internet connectivity

On top of line call results, eyes3 can provide the complete data on the ball trajectory, such as ball
speed, ball height, ball spin, landing positions. For example, eyes3 can delivery ball speed at
different locations, such as serving speed, as well as the ball speed at the receiving side. Players
will also want to know the ball height when crossing the net, as well as the ball height at the
receiving side. These data provides valuable information to help players and coaches to
understand and improve their shots.
