Trajectory detection and feedback system
First Claim
1. A device for providing trajectory detection and feedback, the device comprising:
- one or more sensors for detecting physical information used to characterize a trajectory of an object launched along its trajectory by a human;
a logic device designed or configured to i) generate trajectory parameters that characterize one or more states of the object along it'"'"'s trajectory from the physical information and ii) generate feedback information using the trajectory parameters; and
one or more feedback output mechanisms for providing the feedback information to the human.

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. The feedback information may include one or more trajectory parameters that the human may use to evaluate their skill at sending the object along a desired trajectory. 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. After the system has evaluated a plurality of shots by the player, the system may provide 1) a diagnosis of their shot consistency, 2) a prediction for improvement based upon improving their shot consistency and 3) a prescription of actions for improving their consistency.
