Systems and methods for tracking basketball shots
Methods and apparatus related to improving player performance for trajectory-based sports are described. In particular, sporting devices are described that can be utilized to improve player performance in basketball. The sporting devices can include a camera-based system configured to capture and analyze the trajectory of a shot taken by a player. The camera-based system can be configured to provide feedback that allows a player to optimize the trajectory mechanics associated with shooting a basketball. In one embodiment, the camera-based system can be used in conjunction with a training aid that is attached to a basketball rim. The training aid can be configured to improve the trajectory mechanics of individuals utilizing the modified basketball rim to practice their shooting.
