Device must be positioned in the tripod in landscape orientation. Portrait orientation is not supported.
Close up shot of the table, containing the whole table, with pockets near the top and bottom borders of the frame (see the sample image for reference).
Only required balls in sight. Other balls should be kept out of sight, within the pockets, or somewhere outside the frame of the camera.
Tripod height must be +5 feet, placed approximately four feet apart from the table.
Tripod must be stable and motionless. Bear in mind this is may be harder to achieve with iPads.
Well lit environment, ideally with white light. Yellow light might throw off the AI as the cue may appear yellow, and the one ball may appear white.
Rear camera of the device works best, as it provides better image quality.
Make sure the cue is always in sight of the camera, avoid blocking it with your body. If necessary move the tripod for a more comfortable shot.
Make sure only one table is captured in the shot in places where there are multiple billiard tables, such as pool halls.
Typical cloth colors, such as green, will work best.
The following is a sample shot, as reference:
Tripod should be at least 5 feet in height, with 7-8 being the ideal height.
Any cloth color is supported. Typical colors such as green or tournament blue work best.
You should place the balls specified by the instructions of the drill and not others. In scenarios where any ball will do know that solids tend to work more accurately.
A grid of white dots should appear on screen. If the dots coincide with the intersection of diamonds of the table it means it's being detected successfully.
There are three ways to achieve this. The first one is to use screen mirroring from your device to an AppleTV enabled screen to be able to see in a big screen the expected positions, and score dashboard while you play. The second one is to toggle the camera used to use the front facing camera to achieve the same result. Know that accuracy will suffer as image quality of front facing cameras is lower than rear facing cameras. The third option is to learn by heart the expected positions of the balls for a drill from the diagram, which are aligned with the intersection of diamonds, and rely on audio feedback from the virtual coach when the layout is ready.
You can, just make sure to grant the app some seconds with the tripod in a stable position to home in the table again.
You may change the voice of your virtual coach in the app's settings. Currently there are two options.
