TRAJECTORY DETECTION AND FEEDBACK SYSTEM
First Claim
1. A basketball training system comprising:
- a backboard;
a basketball hoop;
a playing area;
one or more bounding structures arranged around at least a portion of a perimeter of the playing area;
a trajectory analysis and feedback device comprising;
one or more sensors for recording sensor data used to characterize a trajectory of a basketball shot by a human;
a logic device designed or configured to i) receive the sensor data, ii) generate trajectory parameters that characterize one or more states of the basketball along its trajectory and iii) generate feedback information using the trajectory parameters; and
one or more feedback output mechanisms for providing the feedback information to the human wherein the feedback information is related to one or more of the following trajectory parameters;
1) an angle of the trajectory relative to a plane of a basketball hoop when the basketball is proximate to the basketball hoop or
2) a point on the trajectory relative to a fixed point within the plane of the basketball hoop when the basketball is proximate to the basketball hoop.

Abstract
A disclosed device provides a trajectory detection and feedback system. The system is capable of detecting one or more moving objects in free flight, analyzing a trajectory of each object and providing immediate feedback information to a human that has launched the object into flight, and/or one or more observers in the area. In a particular embodiment, a non-intrusive machine vision system that remotely detects trajectories of moving objects may be used to evaluate trajectory parameters for a basketball shot at a basketball hoop by a player. The feedback information, such as a trajectory entry angle into the basketball hoop and/or an entry velocity into the hoop for the shot, may be output to the player in an auditory format using a sound projection device. The system may be operable to be set-up and to operate in a substantially autonomous manner
