Trajectory detection and feedback system

A basketball training system comprising:

• a backboard;
• a basketball hoop;
• a playing area in which the basketball hoop is located for permitting a human to launch a basketball toward the basketball hoop from the playing area during a basketball shot by the human;
• one or more bounding structures arranged around at least a portion of a perimeter of the playing area, the one or more bounding structures for blocking the basketball from leaving the playing area and defining a boundary of the playing area such that a width of the playing area is less than a width of a standard basketball court;
• a rotation mechanism for rotating the backboard and the basketball hoop;
• an input device configured to receive at least one user input for selecting at least one orientation for the backboard during at least one basketball shot, wherein the rotation mechanism is configured to rotate the backboard based on the user input such that the backboard is moved to the selected orientation;
• and
• a trajectory analysis and feedback device comprising:
• one or more sensors for recording sensor data used to characterize a trajectory of the basketball shot by the 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 the 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.
