Shot Detection, Classification and Swishes


SIQ Basketball detects and tracks your shooting when you play basketball. You can take any kind of shot (catch and shoot, off the dribble, or relaxed shot like a free throw) and the ball even classifies the shot into those categories. The ball is based on leading edge machine learning algorithms that detect and analyze your shots. The accuracy of the shot detection algorithm is over 99%, which is an achievement of which we are very proud.

However, just counting your shot attempts only tells that you are practicing, but it is not enough to track your progress. The ball classifies your shots into makes and misses by analyzing the interaction between the ball and the hoop. The accuracy of the shot classification is over 95%, which more than enough to evaluate your progress.

Tracking your makes and misses does not tell the whole story about the reliability of your shot. For example, a shot that hits nothing but the net is more likely to go in than a shot that bounces on the rim. You can increase the chances of making your shot by aiming at the center of the hoop and putting enough arc into your shot. The ball counts your swish percentage to tell you how many of your makes hit the sweet spot. The higher the swish percentage, the more reliable your shot.

There are a few requirements for you to get most out of your SIQ Basketball:

• You need a regulation height basket
• You need a proper and unbroken net
• You need to place the phone within 30 meters or 90 feet of the ball

Finally, there are some known situations that may lead to unexpected results:

• Airballs might go undetected (as they look a lot like lob passes)
• Shots that hit the front of the rim and graze the net might be classified as makes
• Shots that bounce on the rim for more than two seconds
• Sloppy bounce passes can cause false detections
• Some layups and dunks might still go undetected, but we are working on it!
